I am queen of Procrastination. How can i overcome it?

Ok, so I have finals all of this week, and I, being the freshman that I am, of course, am PANICKING! I have a serious procrastination problem, and can only work well under pressure. I know this is like really bad, but do you have any suggestions to study? I have 6 tests, over the course of 3 days. And no, I don’t have like ADD or whatever, its just lack of wanting to get things done… Hope you can help! Do you have suggestions on last-minute studying for exams?
