Any UCLA students that did A-level or IB or anybody that can provide insight?

So the admissions contract states that I should perform “at a similar standard” to the predicted grades reported on my application. Now, they also give a benchmark that I shouldn’t fall below. So I’m personally taking A-level and my predicted grades are A*AA and they said I should perform at a similar standard to this but that A-level students should absolutely not fall below a B in any subject.

So, my question is: Do I absolutely have to attain my predicted grades or do I have a bit of leeway? For instance, would my offer be revoked if I got AAA or AAB rather than my predicted? Thanks so much!
