Before the periodical test, I managed to review my lessons all by myself but the problem is, I don't have enough notes to be used for my review sessions. But anyway, I still have notes even I'd lack of it, I tried to recall of what i've learned about those subjects. During the test, we cannot avoid of mental blocked just like what happened to me. I don't know why is this happening to me but at least, I know how to control it because of the tips that a friend gave to me. And after the test, I feel more comfortable because it's already over.
So for the coming of the next test, I'll try harder in order to pass the incoming final grading and examinations ...
