...that students ignore:
1. Here's a trick. Before class, just quickly look over what we're going to learn. A couple of minutes of preview will make everything so much easier to understand!
2. Check the odd problems as you go so you don't find out later you did all of the problems incorrectly.
3. You say you can't study for math. Make a cheat sheet. [Can we use it on the test?] No, just make it, look at it, and throw it away before the test.
Any more? Even better - and ideas on how to make them act on our nuggets of wisdom??
