I haven't started revising yet for the exams cause I don't feel the need to (and really cba). Wouldn't it just be ok to revise for the exam the day before the exam, and when I have multiple exams on one day, I spend multiple days revising for that day? If I revise physics for example now, then I revise it the day before the exam, its basically the same as only revising the day before as I am using the same revision materials so I won't learn anything new...
