California State Testing Help!?!?!?

I have CSTs this week. I have 3 B's and 3 A's. I did math and english for the California State Testing. I know I didnt do well on them. I am a type of person that learns and then forgets. Will I need to retake the classes if I dont score good on the CST? I am taking Chem, Algebra II, Modern World History, and English. I am doing well in the class but I am concerned if I dont get a good score on the CST. Thanks. No ruder comments Please. I am leaving to do the test right now.
