TAKE NOTES IN CLASS! Direct notes from Brock are the most helpful. When you go home, study those. When you are asked to make flashcards, make sure they're good so you can study those as well. The videos Brock eventually gives you to watch are very helpful also, don't take them for granted. The packets he gives you may seem long and useless, but if you read them, they do give you some things that you didn't know before.
