LSAT Test Day: Photo, Not Thumbprint

LSAT Blog Test Day Photo ThumbprintUPDATE: A variety of hilarious sample photos, mostly centered around how NOT to take your LSAT Test Day photo, are available on LSAC's website.

The following is an important public service announcement from the Law School Admission Council (LSAC):

Greetings from Newtown!

I write to remind you of a change in the way LSAT registrants will provide identification at testing sites. Starting with the June 2011 test, LSAC will no longer thumbprint LSAT candidates. All registrants will be required to affix a recent photograph to their LSAT admission ticket. The photograph must have been taken within the last six months and show only the candidate’s face and shoulders. It must be clear enough so there is no question about identity, and it must be no larger than 2x2 inches or 5x5 cm and no smaller than 1x1 inch or 3x3 cm.

Previously, only registrants for Canadian and international test centers were required to affix a photo to their LSAT Admission Ticket. The new rule makes identification requirements consistent for all test takers.
So, everyone taking the LSAT in less than 6 months, please go out ASAP so you don't forget to get the required photograph. Put it in a safe place.

Regardless of when you're taking the LSAT, add the word "photo" to your calendar next to "I love the LSAT" so you'll remember to bring it. The required photo size is approximately the same as that of a typical U.S. passport photo, which you can typically get at many post offices or chain pharmacies.

As annoying as it is to go out and get a new photo just for the LSAT, I guess you can be glad that getting a thumbful of ink is no longer a requirement for Test Day.

Here's some more information about LSAC's Test Day requirements regarding the photo, from the Day of the Test page of their website:
all candidates must attach to their ticket a recent photograph (taken within the last six months) showing only the face and shoulders. The photograph must be clear enough so there is no doubt about the test taker's identity, and must be no larger than 2 x 2 inches (5 x 5 cm) and no smaller than 1 x 1 inch (3 x 3 cm). Your face in the photo must show you as you look on the day of the test (for example, with or without a beard). The photograph will be retained by LSAC only as long as needed to assure the authenticity of test scores and to protect the integrity of the testing process.

If you do not present both acceptable identification and the required photograph, you will be denied entrance to the testing room.

What are you planning to wear for your LSAT Test Day photo shoot?


LSAT Prep Diary: Retaking the LSAT Plan

LSAT Blog LSAT Prep Diary Retaking LSAT PlanThis installment of LSAT Diaries comes from John, who's retaking the LSAT in June 2011.

In this diary, he talks about what he'll do differently this time around.

John's LSAT Diary:

I am taking the LSAT for the second time in June 2011.

I've been down this path before, while prepping for the October 2010 LSAT. I scored 170 on my first PrepTest and, within 6 PrepTests, I was hitting 173-174. This was going to be a piece of cake. I was different than than all those people asking if 20-point increases were possible in 3 months. I believed I had a god-given ability to think logically. I cleared my entire summer schedule, and believed it was my destiny to ace the LSAT...man was I wrong.

I began to take the test less seriously, taking long breaks between sections (days). Every perfect section was celebrated with a night of drinking, and every wrong answer was waved off...("oh that was a stupid mistake, i definitely won't make that on the real test"). My rigid schedule broke down and my 100-day countdown timer evaporated.

My Facebook was reactivated, my no-alcohol ban was lifted, and I cruised into the test believing I'd receive a 2-3 point "concentration boost" on the real test. Then the real test came: I was confused for the first time ever on the logic game, the distractions, the 6 sections, the lack of smoke breaks, I was not prepared....I ended up scoring 10 points below my mean.

After that...I went on a law hiatus. Fueled by the scamblogging talk about the legal market, I began to focus on breaking into investment banking instead. Long story short...I realized I couldn't apply a cost-benefit analysis to my career choice. I want to do law. Sure the chances of success aren't great, the work will be hard, but I don't care. I knowingly accept the risks of the path I am taking. The safety net is gone, and I am graduating soon. I will pour my heart and soul into this LSAT, not just for the points, but just to know that at one point of my life...I went for it all in. Life only presents a few opportunities where a man/woman can truly fight for his destiny..and this is one of those times.

Words only mean so much, time for action. I am starting right now, even though it's a week from Finals. I am planning on studying 4 hours a day for now, and taking full LSAT PrepTests after my finals are over.

I will...

-keep my days tracked down to the hour...no more unaccountable breaks.

-eliminate my unnecessary distractions: Facebook is gone, soon I'll stop tracking the NBA and other vices.

-treat every answer that I am not completely sure of as wrong. I won't reward my luck when I guess.

-analyze every mistake. I made it for a reason, and I will break it down and find out why.

Thanks for reading. I hope you'll join me for this journey. I'd love to hear your questions and comments. I was served a massive slice of humble pie last time around, and I no longer have an ego. If someone has something to say, I am definitely all ears. I believe the biggest enemy is myself, the mindset, the concentration, etc. I'll detail how I work through these things along with specific LSAT deficiencies.

It's time for the hardest part...the beginning. Thanks for reading. Let's do this together.

LSAT Crash Course Diary: You Can Do It, But You Shouldn't

LSAT Blog Diary Crash Course Can Shouldn'tIn this LSAT diary, Ricky describes how he retook the LSAT and improved his score by 7 points in just 6 weeks.

If you want to be in LSAT Diaries, please email me at LSATUnplugged@gmail.com. (You can be in LSAT Diaries whether you've taken the exam already or not.)

Thanks to Ricky for sharing his experience and advice, and please leave your questions for him below in the comments!

Ricky's LSAT Diary:

I took the LSAT twice, in December 2010 and then again several weeks ago in February 2011. The first time, I received a 153 and the second time, a 160. A lot of snobs turn the cold shoulder and dismiss anything south of 165. Pay them no mind. Everyone has different goals.

Personally, I take comfort in the fact that out of 100 college-educated people who took the LSAT in February, I did better than 80 of them. Given that, and while I am very happy with my score, and the improvement I posted and can show to law schools, I feel that I am still 5-10 points of where I could be if I did this thing right. However there is little I can do about that now (I need to go to school in the fall). You live and you learn and you can’t change the past, learn from it and move on.

One of the big things I heard about the LSAT before I really dove into it is that you either “got it or you don’t”. This is both right and wrong. For example, a very good friend of mine who is now on a full ride at a top-tier law school (ass), did his undergrad in engineering and just for shits and giggles decided to take the LSAT and got a 172 on his first practice test. I hate him, not really, but I do. I wasn’t so lucky. I thought to myself “Hey, it’s a logic-based test, I’m a logical guy, and usually a good standardized test taker, I got this, no problem.” HA! This is the first of many examples in the next few paragraphs that show me being an idiot.

This fall, I worked as an outdoor education instructor in Texas. While one would assume that a teaching job in outdoor ed would provide ample time for studying, that was not the case. We were short-staffed and overbooked. As a result, 60-hour weeks featuring 2-3 nights and intermittent Saturdays working outside in the Texas sun were the norm. While I’m sure there are some of you who have studied facing similar obstacles, I just could not do it. I registered for the LSAT a week before the deadline, found some study material and bought a book of 10 PrepTests.

In the next weeks, I finished probably 70 pages of the book and maybe a section of a practice test by the time I finished the season in Texas and moved home to start really studying. I had exactly 12 days to L-Day (get it, like D-day but for the L-SAT…hahaha, I don’t care if anyone else laughs, I thought it was funny).

8 days before L-day, I took my first practice test. 148. Shit.

That test just whooped my ass, it shocked me. I’ve been out of school for almost three years; I haven’t had to think like that in a long time. I mean, there is no way they expect me to read those four incredibly dense reading passage filled with paragraph-long sentences about the diet of caveman and how archeologists are using dental fossils to determine what they ate and finish 27 questions in 35 minutes…do they?? I’ve never taken a test that hard before. You know what, whatever; I’ll do much better tomorrow.

The next morning, took it again. 149. Shit.

I still had my sanity and my composure at this point, let’s give it one more try tomorrow. Halfway through my third test in as many days, I cracked. It was the infamous mauve dinosaur logic game that pushed me over the edge. I did not even know where to start on the problem. I didn’t understand how to start, after four or five minutes, I couldn’t even get the first answer. .I stopped working, slammed my fist on the table, hurled my practice test into a wall, and let fly a chain of expletives.

What does this have to do with Law School let alone the practice of the law? Why does this friggin clown have such complicated requirements for how it needs to dress (December 2006 LSAT Logic Game) The average LSAT score is 151, and I couldn’t even get THAT. I was frustrated, terrified, panicked, and angry.

I started looking at this blog a couple of days before the meltdown and mustered the energy to leave the fetal position and email Steve (editor of LSAT Blog) a whiny email explaining the situation and asking for help on a LSAT Hail Mary. He promptly responded with some encouragement and references to a few past posts that helped me out. Soon thereafter, I accepted the fact that I am remarkably stupid for thinking I could beat the test in two weeks and decided to take the test in December as a dress rehearsal. Once I accepted that, I went into the test relaxed. The pressure was off, I was going to retake in February.

The only thing that really threw me off on test day was having to write the “certifying (I won’t cheat) statement” in cursive. What am I in - fourth grade?? Could the LSAT get any more archaic?? I haven’t written anything more than my name in cursive in over a decade. Just stupid. Besides that, it was hard, but I felt alright about it. In early January, got the score back 153….

Time for ROUND 2!

After a few days off, I bought another round of books. I realized that I still put myself at a disadvantage. From everything I read, they said to really improve it takes 3-4 months of studying. I had about a month and some change to go before L-Day Part Two: Ricky strikes back (that’s what I named the second L-day, get it, because its like the 2nd Star Wars movie….whatever, don’t judge me)..

I moved back to my home state, Iowa (God’s country) and started studying the right way. I took Steve's advice and started breaking down my practice tests, grouping the questions and analyzing which ones I needed to improve upon. I used that information, targeted those areas and the scores on my pt’s started to creep into the consistently into the mid 150’s. I stopped any partying (which was pretty difficult while moving back to a college town and working at a bar) and was studying 4-5 hours a day. My scores on LR and RC were drastically improving.

Believe it or not and contrary to popular belief, I think RC might be the easiest area to improve on once you understand how to read the passage and keep track of the points of view. I was still getting my ass kicked by logic games; my mind just doesn’t work like that. I knew I didn’t have enough time to get really strong at those games so I did what I could and I focused on two of the more popular types of games, linear and grouping, and did what I could moving forward. My scores were now around 157-158 consistently and I was starting to feel better. I set my over/under on test day at 157, got it and I would be content, over happy, and under pissed. Bring it.

Luckily, I never have really gotten test day anxiety, and I felt good going in. The test itself is a blur. LR felt harder, until I thought about it and realized that all LR sections, past, present, and future are the same. I got caught spending too much time on one RC passage, but thought I recovered alright, and the games were slightly less awful than usual. There were several people in my testing room that felt the need to have a coughing competition at the end of one section; lsat during flu season is a crap shoot. I felt good, it was over. I went to aforementioned bar and got reacquainted with my friend, Jameson.

Test score came back a month later, 160. I was happy. Here is my advice for all of you:

* Do not cram, you will lose. It can be done in two months with some success, but it shouldn’t be. If I had another month or two to study, I could be several points higher, I’m sure of that.

* Do a ton of practice tests in real conditions, three sections, ten minute break, two sections. Do not deviate from that, no allowing extra time, answering a text, working after the buzzer or taking a bathroom break.

* Get an LSAT study plan from Steve and simplify your life. Know your weak areas and attack them. Understand how/why you got every question wrong.

* Come up with a badass playlist to listen to on L-Day. I chose All I Do Is Win by DJ Khaled, It’s My Time by Fabolous ft. Jeremiah, and Here I Come by The Roots. That stuff gets you jacked!

* Do your research before buying books/signing up for a prep course. Don’t sign up for Kaplan because they have an “improve your score guarantee.” Anyone who is exposed to the test that much is going to improve their score no matter what. It helps for some, but you don’t need a prep course to improve. Use the books but adapt the strategies to fit your strengths. Don’t diagram too much on LG’s, and don’t underline too much in RC. You're wasting time you don’t have.

* Relax on Test Day morning. I know it is easier said than done, but if you’ve done the appropriate prep you will be fine. If you have done PrepTests under the right conditions, nothing is new. The worst thing you can do is freak-out about it, get out of your head and trust yourself. If something throws you off, take a deep breath, close your eyes for a second and move on.

As much as I hate to say this, I do miss studying for the test. You know you’ve crossed an unfortunate plateau when you start laughing at jokes about sufficient and necessary conditions and finding logical flaws in conversations about anything. Love it, or hate it, but if you want to be a lawyer it has to be done. Hit me up in the comments if you got something to say. Try to have fun with it. This video does a good job of running through the gamut of LSAT emotions, particularly how good it feels to be done. Good luck.

Logical Reasoning: Inference Questions and the Contrapositive

LSAT Blog Logical Reasoning Inference ContrapositiveA while ago, I did a brief post covering one simple format for formal logic inference questions in the LSAT's Logical Reasoning section.

However, they can follow a variety of formats - not simply that particular one.

In this blog post, I'll cover another common type of inference question - one in which the stimulus first sets up a conditional statement. The stimulus then provides us with a clause that activates the sufficient condition of the contrapositive of the previously-provided conditional statement.

***

I know that was a mouthful.

What do I mean?

Suppose a Logical Reasoning stimulus is composed of a conditional statement, like X -> Y, as well as the additional information, NOT Y.

We can then take the contrapositive of that conditional statement, NOT Y -> NOT X, and plug in the additional information of NOT Y to spit out the result, NOT X.

***

Must Be True Example

This is all a bit abstract, but let's look at it with an example from a real LSAT Logical Reasoning question, a Must Be True question:

(Please see PrepTest 30 (December 1999 LSAT), Section 2, Question 20 - page 59 in Next 10 to follow along. Due to copyright law, I'm unable to reproduce the text of the question itself.)

This stimulus begins with a claim made by critics saying (paraphrased):

If continued public funding is justified, then there must be some indication of public benefit.

We can diagram their claim with the following symbols:
CPFJ -> IPB
The stimulus continues by saying that if the critics' claim is true, then there would not be tremendous public support.

We can diagram this statement with the following symbols:
"CPFJ -> IPB" -> NOT TPS
Rather than using the word "NOT", I'd probably draw it instead like this:

LSAT Blog Logical Reasoning Inference Contrapositive


I placed the critics' claim in quotes to indicate that the truth of their conditional statement's claim is serving as the sufficient condition of another conditional statement - the one with the necessary condition being (paraphrased), "then there would not be tremendous public support."

However, it doesn't simply say then there wouldn't be tremendous public support - it says, there wouldn't be all the tremendous public support that we do, in fact, have.

In other words, we DO have tremendous public support (diagrammed as):
TPS
As such, we can now take the contrapositive of the big conditional statement we just talked about:
"CPFJ -> IPB" -> NOT TPS
If there is tremendous public support, then the critics' claim that "in order for continued public funding to be justified, we must have an indication of public benefit" is NOT correct.

In other words, if we have tremendous public support, then an indication of public benefit is not necessary in order for continued public funding to be justified.

We can diagram this as:

TPS -> NOT "CPFJ -> IPB"

Again, rather than using the word "NOT", I'd probably draw it instead like this:

LSAT Blog Logical Reasoning Inference Contrapositive


Since we do have tremendous public support, then we can conclude that the critics 'claim is not correct.

NOT "CPFJ -> IPB"

Choice E of this question pretty much says just that.

***

Recommended assignment:

Now go through this process with another Logical Reasoning question that follows a similar format. I recommend PrepTest 31 (June 2000 LSAT), Section 3, Question 22 - page 101 in Next 10.

2012 US News Law School Rankings Released

LSAT Blog 2012 US News Law School Rankings ReleasedThe 2012 U.S. News law school rankings were just released this week.

Here are the 2012 U.S. News Rankings for the top 14 law schools (some are tied):

1. Yale
2. Harvard
3. Stanford
4. Columbia
5. Chicago
6. NYU
7. Michigan
7. Penn
9. Berkeley
9. Virginia
11. Duke
12. Northwestern
13. Cornell
14. Georgetown
14. Texas at Austin

There aren't too many huge changes to the top-14 law schools (the biggest is the addition of Texas), but U.S. News has begun ranking some of the lower-ranked law schools, rather than lumping them all together.

Lots of analysis (and links to other analysis) on AboveTheLaw, this U.S. News article, another one on changes in how the law school rankings are calculated, and one in the Wall Street Journal.

Sudoku Puzzles for LSAT Logic Games Prep


"Sudoku for LSAT prep - on STEROIDS!"

If you're into sudoku, you've probably heard of DJAPE. His Samurai Sudoku puzzles appear in the Washington Post and many others around the world.

He's been kind enough to work with me to put together another sudoku book - a collection of sudoku puzzles and sudoku variants exclusively for LSAT Blog readers - LSAT Blog's More Sudoku Puzzles for LSAT Prep.

LSAT Blog Sudoku Book Covers



But why are there TWO books in the photo?

Because I've also put together a book of 208 easy-to-medium difficulty sudoku puzzles, along with a brief introduction to sudoku.


"What are sudoku variants?"

They're puzzles just like regular sudoku, only with a twist.

Sudoku variants can include things like:

outside sudoku, consecutive sudoku, jigsaw sudoku, diagonal sudoku, and tridoku.

If you've never heard of these variants, don't worry. The book explains how to approach all the included puzzles in the introduction.


This book contains 50 sudoku variant puzzles along with 300 regular sudoku puzzles. 

That's 350 puzzles altogether!


The puzzles are placed in order of increasing difficulty, and we've included the answers at the very end so that you can check your work or sneak a peek.


You can have this on your computer within minutes, and you can print out as many copies as you need.

You can print and carry a few of them with you, rather than having to carry an entire book. You can also print out multiple copies of the same puzzle so that you can do and redo it without having to erase.



Why practice sudoku for LSAT prep?

Many of you have been asking me for a good way to prepare for the Logic Games section without getting into the actual LSAT material.

And solving a sudoku puzzle requires a little something nerds call "deductive reasoning."

Basically - making inferences!

Sound familiar? It's the exact same thing you have to do in LSAT Logic Games, so sudoku's a great tool for developing the skills you need.



This sudoku book is for you:

if you plan to take the LSAT down the road and want to get an early start on your prep 

if you don't want to expose yourself to the limited number of real LSAT Logic Games out there

if you just want to take a break from the LSAT without completely wasting your time on social media and Netflix


Get both books (208 regular sudoku and DJAPE's book) for only $17.94:

CC



Get your copy of DJAPE's book for only $9.97:

Get your copy of the 208 regular sudoku book for only $7.97:


CC



Fun Fact:

This is a PDF available for instant download. It'll be sent to whichever email address you submit.


P.S. DJAPE's book when paired with the one containing 208 easy-to-medium difficulty puzzles is a lethal combination.





LSAT Diary: Law School Acceptance Call

LSAT Blog Law School Acceptance Call LSAT DiaryThis installment of LSAT Diaries comes from Kerrianne, who previously wrote an LSAT Diary about her prep.

In this LSAT Diary, she updates us on her experiences (and acceptances!) in the law school admissions process.

If you want to be in LSAT Diaries, please email me at LSATUnplugged@gmail.com. (You can be in LSAT Diaries whether you've taken the exam already or not.)

Please congratulate Kerrianne below in the comments!

Kerrianne's LSAT Diary:I'm done with the LSAT and have been for awhile. My GPA is "good " and I go to a great school. The College of Business I am enrolled in is ranked nationally. My work experience is outstanding and I have been published for my research in my law professor's book.

Furthermore, I knew that I would have great letters of recommendation as I have worked hard for the past four years. I revised my resume and made it 2 pages (many law schools allow this because there is no interview and they want to get to know you as best as possible.)

I have applied to three schools so far and I really only want to apply to one more. I have been accepted to two of the three and I have yet to hear back from the other one. Funny enough I got accepted into a school in California that I didn't even apply to. Something about that makes me wonder... how could they grant admission to someone when they haven't viewed my resume or personal statement?

Anyway, so far my favorite part of the whole LSAT/Application process was that I attended Graduate School Fairs and Pre-Law Fairs and I developed a good relationship with the three recruiters from my top 3 favorite schools. I have been able to keep in contact with them for the past few months which has alleviated some stress in my life.

My applications went in the week of Christmas (Happy holidays, let me into your law school), and while I was still at home over break my cell phone rang. That is a pretty weird thing to happen as I despise talking on the phone and anyone who has my number knows that. I didn't answer the phone because I didn't recognize the number, but when I listened to the voicemail I heard the voice of one of the recruiters telling me to call her. I immediately thought "What did I forget to do on my application?" I called her back, we made small talk, and after a few minutes she told me that she was calling to congratulate me on my acceptance into their law school.

6 days before my letter of acceptance crossed her desk. You can try to imagine my excitement as I thought the call was about me messing up my application only to find out that I was accepted into the law program. It is worth it to communicate frequently with the recruiters. I jumped up and down for awhile, told my mom, called my dad, text my sisters, and emailed the attorney I work for. I will always remember that call because it made my dream a reality:

I am officially going to law school!

While I wait to hear back from another school or two more I have considered retaking the LSAT, as a higher score (I kid you not - one point higher than my score) would make me eligible for good scholarships, but I've decided against it. Why you ask? Retaking the LSAT is a $200 investment that can save me $1,000's. I've gone back and forth over this decision but really it is quite easy. I spent a huge portion of my Senior year fall semester hunched over with my nose in every LSAT book I could find, I did my LSAT time and I'm done. Loans will cover my expenses and when I am the next big attorney I can pay them off. For now I will enjoy my senior year as much as I can (though I still have two jobs and 17 credit hours.)

The LSAT helped me reformat my discipline and study habits, I got straight A's last semester with two jobs with that silly LSAT test consuming my life.

The LSAT is over for me, its time to usher some new law school hopefuls into the "worry zone." I've spent far too long here and I'm happy to leave. I will be in law school in a mere 6 months and I cannot wait.

I wish the best to all of you Law School hopefuls. The stress can be awful but it will all be worth it when you have a law school education.

I hope my ramblings have eased the pain of studying (if nothing else I got you away from those PrepTests for a little while.)

Because the contrapositive of this statement is simply a rewording of the argument itself, the contrapositive of that statement is both necessary and sufficient for that argument to work.

As such, it can serve as the correct answer to both Necessary Assumption and Sufficient Assumption questions.

***

Necessary Assumption
Let's start with the fact that the contrapositive of an argument's evidence-conclusion link can serve as a necessary assumption.

I mean that if X -> Y is an argument, then NOT Y -> NOT X is a necessary assumption (an assumption required) for that argument to be valid.

After all, if the contrapositive were negated, then the original statement would not be valid either, and the argument wouldn't be valid. As such, the original statement requires the contrapositive to be true as well.

***

Sufficient Assumption

Additionally, the contrapositive of an argument's evidence-conclusion link can serve as a sufficient assumption.

I mean that if X -> Y is an argument, then NOT Y -> NOT X is an assumption that is sufficient for the argument to be valid. What I mean is that if we're told, as new information, that NOT Y -> NOT X is valid, it must be the case that the argument itself (X -> Y) is also valid. This is because if the contrapositive of a statement is valid, then the original must also be valid, since they're logically equivalent.

This is all a bit abstract, but let's look at it with a couple of examples from real LSAT questions:

Necessary Assumption example:

(Please see PrepTest 36 (December 2001 LSAT), Section 3, Question 16 - page 275 in Next 10)

In this argument, the stimulus tells us (paraphrased):

Because reptiles can't make big behavioral changes when the environmental changes a lot, reptiles aren't capable of engaging in advanced thought

In shorthand, the argument is saying:

NOT capable of big behavior changes with environmental changes -> Not capable of complex thought

The contrapositive of this statement would be something like:

Capable of complex thought -> capable of big behavioral changes with environmental changes

In other words:

If an animal is capable of complex thought, then it must be capable of making big behavioral changes as the environment goes through big changes.

Choice D of this question pretty much says just that.

Again, if an original conditional statement that forms the core of an argument is considered to be true, then it is required that its contrapositive also be true in order for that argument to work.



Sufficient Assumption example:

(Please see PrepTest 36 (December 2001 LSAT), Section 1, Question 26 - page 261 in Next 10)

In this argument, the stimulus tells us (paraphrased):

Because Vermeer used expensive props, it must not be due to a scarcity of props that he kept using the same props over and over.

In shorthand, the argument is saying:

$ props -> NOT due to small # of props that V kept reusing them

The contrapositive of this statement would be something like:

If it were due to a small # of props that V kept reusing them, then NOT $ props.

In other words:

If it were due to a small number of props that Vermeer kept reusing the same ones, then he wouldn't have been using expensive props in the first place.

Choice E of this question pretty much says just that.

Again, if we're told, as new information in an answer choice, that the contrapositive of the argument is guaranteed to be true (or is "assumed"), then the original version of that conditional statement (the one in the argument) must also be true, and the argument is valid.
