Make a schedule you can stick to.

A Schedule 

Too many people treat studying as the thing to do when you get around to it or have some spare time. But if you schedule study time just as your class time is scheduled, you’ll find it becomes much less of a hassle in the long run. Instead of last-minute cramming sessions, you’ll be better prepared because you haven’t put off all the studying into one 12-hour marathon. Spending 30 or 60 minutes every day you have a class studying for that class before or after is a lot easier and will allow you to actually learn more of the material.

You should study regularly throughout the semester for as many classes as you can. Some people study every day, others put it off to once or twice a week. The frequency isn’t as important as actually studying on a regular basis. Even if you just crack open a book once a week for a class, it’s better than waiting until the first exam in a massive cram session.

Scheduling is even more important if you’re going to be a part of a study group. If only half of your members are committed to a study group for every meeting, then you need to find other study group members who are as committed as you are.
