I am currently in year 11 and will be sitting my GCSEs in May and June (for which I'm targeted all A* and A other than a B for English Lit) and don't know whether it'd be better to take 3 or 4 A-Levels. I'm looking to do maths, physics, and then either chemistry or music, but if I get good enough results am considering doing all 4 instead of 3. Is doing 4 a good idea or is the workload overwhelming?
