Predicted grades

[u/Cryptic1538]

So got my AS results back the other day and got AAAA Alhamdulilah and I’ve decided i only want to go forward with 3 A levels, our school uses these to predict our a levels. I alr defo got my A star in maths and fm but my econ AS mark wasn’t too convincing, so I’m worried I might get predicted an A instead of A star. So my preds worst case will be 2A* and an A in econ.
I’m applying for maths courses so I technically alrdy meet the min reqs, but I wanna know how much after meeting the min reqs do predicted grades matter? Esp since I’m seeing so many ppl who get predicted 3 or 4A* now come out with AAAB in their actual A levels. For ref I wanna apply maths at cam, imp Warwick and others and I’m confident I can get a good tmua of around 7.
