The solution sheet for the first problem sheet has been posted. Only 4 people submitted their work on this sheet. That's not a particularly optimal way to get potentially very useful feedback.
I am still awaiting more feedback for when to have the extra class to go over the big picture a bit and also to spend some time on the first homework sheet (though we won't have time to go over everything). Four people have expressed opinions about that. I will wait a little bit more time for others to indicate when they're available, and then I will figure out a day and time from this input.
