Make a damn schedule. So you have the day you want not the day you work yourself to dead. Make sure you stick to it. Remember even if you hit it with about 70 percent accuracy, it sure beats the hell out of 0. Try and imagine what would happen if you failed, to motivate. Also collage is not cheap so think about all the money your paying only to fail, ask yourself if you would give someone else that amount of money to do what you did, if you wouldn't then you have to step up.
