This may not be the advice you are looking for, but if you are the type of person than can teach yourself with good books (a good skill to have in law school) you can probably do fine by getting the Kaplan LSAT prep books and by taking previous LSAT exams.
It doesn’t work for everyone, but it worked for me. Hatzlacha
I agree with Ender. If you are self motivated classes aren’t worth it. The best way to prepare for the LSAT is to take practice tests, as many as possible.
If you find yourself having trouble with a particular area get a book devoted to that area and take more practice questions in that area. Hatzlacha Raba!
