I am the same way. I hate taking tests, I suck at them period.I can know the stuff and it just wont come out when it is test time. I have recently found that flash cards and studying with someone or just saying what you need to say out loud works well. Teach someone what you are studying for. I did that and it helped me. Also, color coding each section, and using a colored pen to take the test. I hope this helps!
