Can a uni revoke my offer if I drop a subject not mentioned in my offer?

I'm a resit student and am planning on dropping Bio since my offer only mentions getting an A in physics - I got an A in Bio last year and a B in Physics - this year I'm resitting both and have a predicted A* in Bio and A in Physics

I don't see the point in resitting both when my offer only mentions 1

i remember coming across a problem like this with my friend. We just called up the uni and asked! They said its fine for us, so try doing the same (calling the uni, not dropping the subject, etc)

Can they? Yes
Will they? Usually not but it’s a good idea to get written confirmation before you drop the resit. Even if they don’t agree you can just turn up to the exam, write your name and draw pictures on the exam sheet and still meet your offer...
