would i get into bath with A*A*C even tho my requirements are AAB

Some Universities are Flexible about entry standards, I would call admissions - I don't think many people on this forum could be helpful, unless they have been in a similar situation and got into Bath University, or if the Bath Admissions team is lurking on this forum.

essentially

studying A and F potentially

Why do you think you're realistically going to get 2 A*s when you don't think you'll get a B in the third subject? They might accept it as it's over the points threshold, but they might not because if the offer states AAB, they might want to see you can consistently achieve a certain level across a range of subjects. The only way to find out is to call the admissions department and ask them.

said it depends on how many spaces they have left

theyre in uhm extra tho so they still have spaces

I think you already have the answer to your question here. Your entry would be uncertain with those grades according to what you've said the Admissions Team claimed.

Kinda different situation grade wise but my offer last year for chemeng was A*AAhoky, I got A*AB with that B 1 mark off an A and they straight up rejected me :/
