Today (September 9) I think there was a help session after class, I couldn't make it due to a class in Lynn right after. Did anybody go/ what was discussed?

And does anyone know what the (?) in our homework stands for?

I asked what the ? was after class, and he said it was just a typo.

It wasn't exactly a help session after class. It was more a few people getting together to make a study group. We are meeting tonight (Sept 10) at 7pm in the Beering lobby.
