It depends on you and what subjects you took for alevels in my opinion, cuz ipad are optional. Having a laptop and phone supposedly enough. But like, if you are the type of person that can study using gadgets (like ipad for sure) without feeling like overwhelmed, losing focus or "tidak masuk otak", then ipad would be a good investment to buy as a student, as you don't have to carry those heavy books and notes. But, if you're into traditional way of studying like using papers and pens and it's actually good for your study, then yeah having an ipad is a yes but not that necessary.
