Ryan Galinkin
I had Ryan as my physics 1 TA and he was awesome! Quizzes are always announced and not too bad. If you don't know something, ask him and he will guide you directly to the answer whether on a quiz or a lab. He's not one to trick you or make you feel dumb. Grading is extremely fair. Having a good TA is very important for a lab, so get him if you can!
