From reddit: Ammar-The-Star says:

This is how I beat procrastination. I went and purchased a little notebook, and every day where it seemed like I had a lot to do, I would write down all the assignments for that day as a list. Things like starting on a paper, do a couple problems, reading the chapter from another class etc. I would then assign a time frame for each one so I know when I should be moving on to the next assignment, and check marked the ones I completed. Eventually I got to a point where I finished everything rather early, and understood the materials extremely well right before the exams and finals. You can also write down other productive things such as getting your workout done or cleaning your car and stuff like that and assign times for them. It changed my lifestyle so much and you should give it a try, it works out incredibly. via
