I'm not a big believer in studying for tests. If you focus, instead, on doing enough homework on a daily or weekly basis, then you really don't need that much studying right before the test. On the other hand, if you haven't been keeping up with the pace of the course, then last minute studying isn't really going to save you.

If you're taking courses that interest you, then it shouldn't seem all that miserable to spend time with your books on a daily basis. If you tend to ignore your academic work until a few days before a test, then ask yourself what you're doing putting all this time in school. You might be better off leaving school and going and getting a job. Why rack up all that student loan debt for a degree that doesn't guarantee you a job anyway.
