So do I replace physics with Chemistry? If yes, if wouldn't make sense to have chem+maths - it would make more sense if its maths+physics. Also maths+physics would be easier due to the mechanics module.
If I add chemistry, either by replacing business or just as my 4th subject, wouldn't I have too much workload?
What happens if I take just AS Chemistry as my 4th subject (ONLY as AS)? Would I be able to see go into the science fields?
