Same boat as you - Law at Bristol / King’s for A*AA
I got ABC for mocks which I revised for, but getting the grades we need is not too far. Depending on your coursework grade, A* is slightly easier for history since with my coursework, I would have an solid A* from an A and it usually make a grade difference. I take chemistry (C) and Economics (B) both which I ran out of time for, and generally could have learnt the content in more detail and done whole past papers rather than specific questions
which are relatively easy to overcome in 9 weeks.
Look at what you did bad in mocks, not just the lack of content and memory, and make sure you have technique down. GOOD LUCK!
