Hi guys, recently I've been contemplating on switching from Physics HL to SL and from Business SL to HL (still on my first year in IB). However, I am planning to take a Computer Science major in either Canada, USA, or Australia. Is it a wise decision to change from Phys HL to SL? I've heard that Physics is a necessary subject for most CS-related majors. Also, how hard is Business HL compared to SL? I used to be a Science student but I've been getting really good grades in my Business SL tests and it seems really easy to me. Any help would be appreciated. Thanks!
