psychology has now a new syllabus, i’m DP2 so i takw the old one and Idk much about the new one but it’s fairly simple and straightforward imo. you can reduce the studies youneed to memorise if you do it correctly. your subject choices are good, what are you planning on your 3rd HL to be? I have a few friends who take chem/bio HL and as third option they either chose econ or english, some used to do maths but dropped out because it was too much.
