TA Help Hours

Chemistry Program TA Help Hours

  • General Chemistry help hours are in-person in S2-126 and on Zoom (see schedule for details).
  • Upper level Chemistry help hours are by Zoom.
  • Please Note: that the teaching assistants (TAs), do not have control over your grades and they are not responsible for your homework and assignments – you are. The TAs will try to help you as much as they can, but they will not give you the answers or do your homework for you. They are here to help you understand the concepts. So, please, attempt each problem before asking for help and have your book and lab manual with you. TAs will help you as you raise your hand. On busy days, be patient.

You are welcome to attend as many hours as you like; the schedule is posted below:
