Hi I am year 13, quintile 1, state school educated and fsm in primary school. I have had 3 contextual offers so far, including from UoN, which offered me ABB.
If grades are what you are worried about, definitely see which other schools you might be interested in. Ik the KCL contextual is ABC which I am praying for, but also alot of universities will offer a foundation year course with significantly lower entry requirements (although notts doesnt).
I would def recommend attending open days tho, I have a friend who has firmed midwifery at nottingham who was able to secure a lower grade requirement while she was at her open day. Also I think Birmingham have a pathways course which might open up some doors.
Best of luck
