preview and review

[bosun]

What is the best way to say preview and review in a natural way? Can I say like

If you want to get a good grade, you should always review class materials as a way to remember them better. Also, before class, you should preview class materials in advance as a way to enhance your understadning during class.


( If you see any problems in grammar or expression, let me have your comments. I want to hear how native speakers express this idea)

You should always review (look over the material so that you remember it). . .

Preview means to watch a movie or a play before it's released to the general public.
