Replying to Math B Regents

For New Yorkers like me, today is the Math B Regents, and other ones.  Up until this year I have gotten really good grades in math but there is just something about math B shit that I cant do.  I think it is because there are many different and complex steps to solve nearly each and every question and if you forget one little trick to any problem, you're fucked.  I am shooting for a 65, which is not that hard to get, considering the retard grade curve bumps you up really good, I think I have to get a 56 or something to get bumped up to a 65.  I know I am shooting really low but I am scared as hell that I am going to do bad, for example, I got a 48 on the practice.  I have been going to all of the review classes that I can and there is a 2-hour review sesh today at the school before the test.  I have taken maybe 10 other regents so far and I have over an 85 average on all of them so I am not that stupid, I just don't want to take this math over again.
