Congratulations on your decision to take the LSAT.
How you prepare for the LSAT during your last month (or week) depends entirely on the type of student you are. For instance, some people get distracted socializing when studying in classrooms or groups. Others get distracted by TV, the internet, or hobbies when trying to study alone. The point is, you must identify when and how you get your best studying done, and try to study in that setting.
Perhaps more important than where and how you study is what you study. During your last month, you should ideally be done learning new LSAT techniques and instead be practicing what you already know. You also want to practice and establish your pace.
Last, you must decide if you are ready to take the test. Although this last suggestion may seem out of place, during your last month you should decide if you are ready to take the test and leave your mark. In other words, decide if you have reached the pinnacle of your LSAT prowess, and if so, go for it; if not, there’s always next quarter.
Anyway, Zap, hope some of this is helps. When you do decide to take the test I hope you knock it out of the park. Best regards and good luck.
