Tutorials aren't mandatory, no iClickers or anything. Then again, 1A03/1AA3 tutorials weren't mandatory and didn't have iClickers when I was in first year either.
Yeah, they give you questions that are taken up by the TA, but most people don't do them ahead of time
The TAs usually go through how you would do the problem, assuming that no one has done the questions, although it depends on the TA. I tried to do it once, and then had most of the answers wrong--I found I learned much better when the TA just explained it
