Some people learn by example.
My homework has become difficult because each time I try a problem I can't remember what I did in similar problems because I had tried so many different things before getting to an answer. This post concerns me. Our goal in structuring this course is to provide LOTS of opportunities for your questions to be answered. We set up the problem sessions so that y'all can ask your problem session instructor questions. If you feel that no one answers your questions, then either something is going very wrong in your problem session, or we simply haven't explained the options well enough to you.
