Learning Newton's law of motion practically overnight?possible?

Ok, so I ain't a physics genius and I have ingeniously decided to cram as my physics exam is impending and portending. I think I am smart and a great self- learner, and if I ever need help I have this handy laptop anytime I want. So about my Q: am I doomed...'cause yesss there are some subjects that need to ruminate in the unconscious a bit (the more difficult ones), I'm just looking for a little fuel to keep me going and tell me if my nocturnal studies are feckless. Thanksss!
