I'll admit, I learned a TON from all the projects, especially since the course moved very quickly.  I found that often I had to learn things on the fly, since the material the projects utilized had to be learned and mastered within a few days.  I rated Project 3 low because it was very challenging, especially to debug.  There were so many details to pay attention to, and one minor mistake could skewer the entire process.

I do appreciate the TA's willingness to help, even if often they were overworked and stretched thin amongst lots of confused, pushy students!
