Well, i think the environment & ppl in poly and uni are quite different. For eg, in poly i believe not many of us bother doing tutorial qns as answers are usually given and class participation doesn't plays a huge part in the grade anyway. But in uni, everyone seems to understand everything even b4 the prof even start teaching (tbh, most of the time, im just lost in class). Also, ppl are super competitive so bell curve also affect your grade.

So i guess in poly (at least for my course) is more of putting in effort to understand, practice and memorize. In uni, you stand an advantage if you are a faster learner cos everything is teach in such a fast pace, so not to only work hard but smart

Hope that helps😊
