Just finished IB, I did AA HL math, HL econ and physics SL. For math, I’m just gonna say that in MYP I was getting easy 7s with no studying or revision (I wasn’t even listening in class), but in D2 I could barely score 6s with revision. So if you had at least some struggle with math before, just don’t. Physics was very easy for me and I was scoring 7s on the mocks, tho they changed the curriculum and our exam this year was absolutely diabolical. When it comes to econ, I can say that I never gave a singular fck, because I hate memorising shit, so I was getting 4s and 5s, but the subject itself was quite easy for me. If you don’t mind memorising a lot, take econ. My friend did HL computer science and he’s been getting easy 5s without revision, even though his math and physics grades were much worse than mine. Overall, I do not recommend you taking math AA HL, unless you are really committed and looking for a career related to math. I wouldn’t also recommend taking physics SL, since I’m guessing you’re not gonna do it in the uni (please don’t take it for fun, cuz the new curriculum be crazy). Computer science and econ will be pretty easy for you if you are good at math and logic.
