Hi everyone. In just a few weeks, I will have to decide on my IB courses for my junior year. Considering how tough IB is, I'm slightly worried about what I should do, especially as I try to decide whether to do 3 or 4 HLs. Right now I'm considering the following subjects as HLs: 1) Biology HL 2) Math AI HL (I want to do AA but it will be extremely stressful) 3) Economics HL 4) Between Chemistry and Computer Science Do any of you have any suggestions on whether I should do 3 or 4 HLs? Also, if you were to rank the subjects chosen above, how challenging and stress-inducing would they be?
