I have been paired up this exact teacher many times when I need help on Chemistry. This teacher does meet my needs but is super super impatient when I am trying to solve the problem. This teacher expects the answer within a super short amount of time before I can even get it to them. This teacher seems just very rude in general.This teacher does not give the student time when they are working the problem out and then gets impatient and gives the student the answer. This is not the best way to go about things because then the student does not actually learn. Thank you.
