(Okay, so I'm being overdramatic and I will feel a lot better after a couple of hours of sleep. But the reason I'm up at 4am in the first place is because I feel too wound up to sleep because there's SO MUCH TO DO AUGH.)
Tutoring this week has been pretty brutally hard because it's midterm exam time and we've got a crapton of students coming in to get reviewed. A crapton of HIGH SCHOOL students. With, among other things, HIGH SCHOOL MATH PROBLEMS oh God. It's been literally six years since I've seen sines or cosines or angles (ANGLES, ARGH) or mathematical proofs and my brain kind of whimpers in terror every time a new student pulls out a new mathy thing they want me to help them do.
So far I've been mostly able to dredge up enough memory of math to get them through the assignment (except that one Physics chapter. My student had pity on me and let me tutor her in economics instead). But it is really tiring. ;_;
