Yeah, at my school they asked you if you were in top few percent of your Gen. Chem class, I couldn't do it because it conflicted with necessary class, but my friend who did it said it was basically a question/answer session...I assume you're not giving lectures because you are still undergrad, but if you understand basic chemistry, and can answer all the random HW problems they'll throw at you, you should be fine...be prepared for some dumb questions though, my friend said 8 weeks into class some people still weren't aware of what a "mole" was...it'll be some sort of leadership opportunity, which is good for something that honestly won't take up much of your time....see if you can do it for GChem 2 as well...good luck
