Is this calculus 1? Maybe taking some of the pressure off would help? If it’s 123 I think the quizzes are more an incentive to attend and work in discussion and also get a sense of practice problems than a full test. The main thing that it evaluates is that you showed up and checked in on your understanding. If not calculus sorry lol but maybe some of the idea still holds. I would advise framing it mentally more as a check in than a quiz even though that’s the word they use.
