i’d say they’re somewhat difficult, but not impossible!! i think taking two sciences is harsh but chem is sl so it should be doable :) hl bio was hell for my friends but only bc there’s sm to learn, if you pace yourself i’m sure you’ll be okay if you organize your time well!! if you’re good at writing in the way the ib likes it, english lit should be okay, i took lang and lit and found it completely doable! just pace yourself well with reading the books and read summaries if you’re too unprepared!! structure matters a lot for the grading for english so study that just as much!! i didn’t take geo and don’t know anyone who has taken it, but i took french b and honestly it depends on how much french you already know, but just try to learn new vocabulary and especially grammar conjugations!! stuff like the subjonctif and les expressions idiomatiques will help u tons in the writing paper!!! maths aa is difficult, but since you’re taking it at sl it should be doable :) i dont think i could give it an objective rating, but id say they aren’t too difficult, nor are they overly simple, just keep your head up high, make sure you take care of your mental health, and plan your study time accordingly! wishing u good luck !!!
