To Tutor?

To tutor of not to tutor--that is the question. The math department head asked me to tutor in the department lab this year. I tried to get a job as an university tutor but I wasn't picked. But now I have another chance. The only problem I have with it--wait, I have two problems. One, it does not really fit into my schedule too well, but it can work. Two, I don't think of myself as much of a good tutor. I don't quite remember everything. But it is a great opportunity to work on my communication skills and gain experience. So I am not sure. But I am leaning towards doing it, probably at least two hours a week. What could go wrong?
