In light of the exam next week, I'll be having extra office hours on Monday from 11:30-12:30, as well as a review session on Monday evening from 6:30-8:00 in DRL A8. Also, one of my professors has scheduled a makeup class on Wednesday morning, so my Wednesday office hour, which is usually 11-12, will instead be held from 12-1.
I hope anybody that wants to see me can make it to one of these times. If absolutely none of them work for you, send me an email and I'll see what I can do, but my schedule for next week is already extremely tight, so the earlier you get back to me, the more likely I'll be able to accomodate you.
