Like really, I'm done with this TA. She all over the place and wastes everybody's time with meaningless thing because she likes to show off how much more she knows than us.

I don't think teachers understand how valuable time is for a student. Please don't ask me to wait for you to finish with other students and then tell me to try again in two days because you've got 30minutes left and can't answer 1 question for me. Yep, thank you for wasting 30minutes of my time. Will you do the physics homework I didn't have time to do? Or better yet, tell my TA that I didn't finish because you asked me to wait and then didn't even end up helping me.
