Monday is a holiday, and then Tuesday is a “Monday.” I don’t generally have office hours on Mondays and I won’t be having office hours on Tuesday as a result (also, I’ll be out of town).
Feel free to email me questions you have about the midterm, though, in the meantime. And I’ll try to be relatively available on Wednesday, so if you want to just schedule a time to come in and talk then, it should be possible to work something out.
