I just registered for the following classes:
IB Physics HL
IB Chemistry HL
IB Math HL
IB English HL
IB Economics SL
IB Spanish SL
I would like to do something along the lines of BioMedical Engineering/Medicine. I should have plenty of credits if I pass my exams. Are there any thoughts on how difficult these classes are, or if I should request a change before it is too late.
