DD is at the moment taking 4 A levels, she wants to apply for Cambridge (history). Head of sixth form wants her to drop one, as if she sits 4, then Cambridge will give her an offer based on 4. Is this true? Her fourth A level is a subject she loves and really isn't ready to give up, but Head considers it not a suitable subject for Cambridge, so it is the one she will have to drop if she has to drop an A level.
I can't see anything online that says Cambridge will offer on 4?
