Hmm, I would say to DEFINITELY learn your anatomy. The teacher from mt. olive wasn't good and i didn't learn anything. Now I'm playing catch-up.
Do the reading. Once you get to nursing, you can't pass without it.
In your pre-reqs, start holding yourself to the standard of making above an 80%. That way, you won't be so stressed once 1st semester starts.
Be friendly to everyone. If you dont work with them in 1st semester in group, you will later on.
If you're in a study group that is bad or doesn't work for you- get out early. And if study groups don't work for you, don't force it. Study alone. You only get so many tests to keep your grades up.
Lecture is the best thing that can happen to you. It's boring sometimes, yes. But, I missed one day of lecture and felt behind for that whole section. Use a tape recorder to help catch the things you missed. And actually pay attention in lecture. If you do, you'll do that much better on your tests.
That's all I can think of for now!
