if its really important to you and like you’ll find yourself getting distracted because you’re thinking about how you haven’t watched it, then it might be worth taking the time to go see it - if you have like a revision timetable then see if you can move things around and slot it in, if not then just make sure you’re taking the time to look over everything. - but it could also be like motivation? Like tell yourself ‘if I study these topics and get a good mark in a practice test then I can go see it’ and that might help. While they’re important, you can’t let your whole life be taken over by exams, that’s not fair to you.
