20. I recommend that yall at LEAST try to study a little bit. You need a decent score on the final test. I know it might be tedious, but at least take 30 minutes of your day to study anything you have trouble with. You do not want to fail your classes.

If your gonna cheat, at least understand what you are cheating on, because I GUARANTEE you guys will fail the finals.
