If you don't know it, you're in big trouble. Remember, where attention goes, energy flows, so do your best and just focus, and I always say it's better to be authentic and to watch it because you want to learn than because you're trying to study for a test. So I know that's hard as a kid to kind of think of, but do the best you can to relax as you watch these lectures and you study. Use other methods. Go to regentsprep.org or my website, hiphues.blogspot.com, for links to other websites that are going to give you more traditional literacy so you can read and you can write and you can do your essays and all of that good stuff. We're just giving you the cheese here, guys. So good luck to all of you, all right?
