<p>depends on many factors. my biochemistry class I never went to except the first day and the day of exams since it was at 8am. This was only possibly because she posted the lecture notes online plus the class hadabout 200 people…same for o-chem. My brit lit class had no attendance policy, but almost all attended regularly since his exams were based off his lectures. I’ve only had one class that required attendance (freshman composition) or else your grade was lowered.</p>
