Do the readings before class!

We've all been through it. We were supposed to read Chapter X of whatever book but we forgot or didn't give it any importance and the next thing you know, you find yourself sitting in class skimming through the pages.

You might as well stop.

Even if you have relatively bad memory like I do, reading through the stuff properly helps. Read and it understand it. Even if it doesn't stick, it'll come back when it comes up in a class discussion. But if you haven't read it at all or have merely skimmed, there won't be anything to come back.

So if you're gonna do it, you might as well do it right the first time.
