What should i drop, if i should?Watch
(This doesn't entirely link) but I know a girl who did the same subjects as you and she continued 4 of her subjects just to get into Oxford and study physics. So maybe doing 4 and getting amazing results will put you at a greater advantage. But then again, it is dependent on you of whether you can take the load. I hope this helps.
Do you enjoy the subjects?
Are you good at the subjects?
Are you orgnanised?
Also, think about if you actually need all 4 for your desired course as universities will only consider 3 grades. I haven't done any research into Medicene/Dentistry as it's not my choice of course, but do you need Physics for it? if you were to drop any, to me, Physics seems like the better one to drop.
If i would be dropping, it would be physics. Maths is too easy to do, and bio and chem are needed. Question is, will 4 A levels help my uni app?
However I think A*A*A is better than AAAA, so if you think your other grades will be affected by doing physics, then drop it, if not then I see no reason why you shouldn't keep it on
