The bar exam is the last test you need to pass before becoming an attorney. Without passing this exam, going to law school was pretty much a waste of time and money. There are a few things you need to do to prepare for this exam.
First, you should sign up for a bar review course. I know it seems foolish to spend even more money on studying for law, but it will be much more expensive in the end to take the test, fail and have to wait around to take it again. The bar exam review will allow you to know how to give the proper answers while also studying topics which are typically on the exam itself. The people who teach these courses are typically those who have already taken the exam and know how to prepare. The majority of courses are worth spending the extra money on.
Second, you shouldn't be planning on seeing friends or family often for at least two months. Those who seriously want to pass the bar exam will lock themselves in their room. Yes, you will have nights off every now and again to rest, but you will want to dedicate a lot of your time to studying.
Third, you need to practice old bar exams. The bar exam that you will be writing will not stray too far away from the old one. You do not need to study them constantly, but just enough to get a basic idea of the format and to know what questions you have difficulty answering. Memorize those questions you get wrong, it will help you on the exam.
Last, go into the exam thinking that you will pass. You have passed LSATs, you have made your way through law school, you will more than likely pass the bar exam. If you study and put in the time you need to to feel comfortable taking the exam, you will do well.
