The problem is, if your score isn’t going up, you need a coach. TestSherpa at http://www.testsherpa.com is a great site for free LSAT advice and also offers coaching. But if you cannot afford coaching, here are some tips.

Think like the test maker. When you practice, don’t just take the questions and get bummed that some were right and some were wrong — really study how each question was written. Can you summarize the argument in the right way? Do you know exactly what an assumption question is asking? Could you write four wrong answers for the question even without reading the answer choices.

When you take practice tests, don’t take the first ones under timed conditions. Work your way up to that. Instead, fold a sheet of paper in half and as you take the test write your exact thinking down in detail on one half, then afterward, study what really was going on and write it down on the other half. This will help you identify the problems that you’re prone to, and will help your LSAT coach diagnose and prescribe for you. And, it will take many hours of work to do this, so again, don’t worry about timing. Only take timed tests when you finally feel like an LSAT expert.
