Excluding homework! Regular homework reinforces the content you have learnt in class. Studying is completely different! Studying can be considered as revising previous chapters, answering practice questions under TIME CONSTRAINTS, and actually attaining a deeper or elevated understanding of the module/chapter. For me, Homework is not the same as studying.
BTW, making notes is NOT studying, although some people do tend to think it is as it is revision.
However, many people have different views!
Hope that helps. Sorry for the informal language! In a rush.... SO MANY ASSESSMENTS and EXAMS! (lol)
