I can tell that you're having a lot of anxiety. Just calm down (I know it's hard! I've been through it!). First of all, you are much more prepared than you think you are. When you're in the test, just be confident in all of the work that you've done. If you're freaking out in the test, you're toast.As far as any additional prep, there's not much you can do now, so close to the test (as far as methods). Just review ALL of the questions in your prep tests. That will help the most. Really attempt to understand what's going on in each question.
