With that being said, you may want to be careful about taking the LSAT again if you did very well and you don't think you can do much better the second time around. If there is a chance of you doing worse, you may not want to take the LSAT again as well.
The site, Top-Law-Schools recently posted an article about an individual who scored 180 on the LSAT. In regards to retaking the LSAT, the author mentioned the following points:
"LSAC keeps track of retakers and reports that most people only improve by a few points at best. They also show that the higher your original score, the more likely you become to go down upon a retake. This means you need to be cautious when approaching a retake. If you prepare for 3 months as best you can, take the test, and score at your practice average, you should probably call it quits. Yet, if you score above 175 very consistently, and then are shocked to find a 174 on your results page, then it may actually be wise to retake even with such a high score.Many people also recommend reading a good book on the LSAT. One such book is available here. One reason why an ebook is great for LSAT study is that it can easily be taken anywhere. For example, you can read it on the subway, on a trip, or between classes. If you are an undergraduate student, you may want to get your hands on this kind of book as soon as possible.
If you don’t improve upon a retake, then you’ve shot yourself in the foot. On the other hand, if you can improve by even one point, then in some cases you may have helped your application considerably. Admissions personnel expect you to improve simply through familiarity with the test, but since your highest score is the one that becomes part of the school’s statistics, the candidate with a 165 and a 166 will probably fare better than the candidate with a 165, all else being equal. I recommend reading TLS’s interviews with admissions deans for more perspective on how they view retaking.
It’s incredibly important that you use your months of practice to establish what your real ability is on the test. If you’re paying attention, you should learn your strengths, weaknesses, and strategies to score higher. You will also learn what score you can expect when you take the real thing. Using this knowledge, you can evaluate why you didn’t score as well as you expected. Was the test center noisy? Did you cut yourself some slack on practice tests without necessarily realizing it? (For instance, some people take long breaks between sections, don’t use a bubble sheet, fudge the section timing, or never practice with an experimental section.) Perhaps most importantly, did you put in as much practice as you should have?
Depending on the answers to questions like these, you can decide if and when you should retake and what you can do to ensure you do better next time. “I was unlucky” is not the right answer, because it excuses you from taking any corrective action."
While I did not write the ebook that is linked above, I highly recommend it. It offers sound advice for vastly improving your LSAT score. If you have taken the LSAT before and are looking to take it again, consider purchasing this ebook. Don't settle for a low ranked TTTT or TTT school when you can improve your LSAT score and get into a top-tier, T14, or even a school such as Harvard Law, Stanford Law, or Yale Law School.
