If you wanna play teach yourself how to use the stupidest freaking program ever called MathCad you can join my group. It is so awesome and doesn't take up the already limited time you have to spare at all. You know sense you have organics lab reports to do on your own time while already spending like 8 hours a week in the damn lab itself, public speaking videos to watch on your own time when there is only like 60 something people in the class, study for all the test you have mainly in Cal and Organic Chem, and cut meat for 40 hours a week.
Oh it is the best damn game in the world. So addicting I tell you.
