I take my exam in 2 days and have so much to go over BUT can't concentrate to study because I'm too nervous. Does anyone have any advice? I keep thinking what if...I don't know enough, I get questions I don't know, can't think clearly to answer them even when I know the answers, get all confused, and have panic attack..!!! I need to calm down to utilize my last couple days of studying....How do you if you're really ready?
