Review of marking

I’m 3 marks away from a A* in further maths and physics and I have met my condition of A*AB (A*A in maths and fm and b in another subject), so it’s non-priority if it ends up worth getting it reviewed. I’ve emailed my university to notify them about this. They have confirmed my place in ucas. While I’m waiting to hear about the review of marking can the university take away my offer? Even if I have met them. It could also take until November 6th to get any confirmation as to whether it has increased or not.
