Unfair Predicted grades

Hi, I'm in year 13 and I received my predicted grades recently. They didn't come out to be quite well (AAB), I was hoping to apply to Cambridge and imperial this year for engineering(aerospace), but now these grades don't even meet the requirements of any universities I applied to(EVEN Manchester). I've spoken to my head of year and access team, they say it's very unlikely to change because its be unfair and unreliable for those who already sent their ucas, and it’s based on how I’ve done in the past years. Although I’ve done reasonably well in GCSE(5A*s,3As and 2Bs) and was given AABB in my AS(could’ve done better if I actually got to do exam), I really don’t see why my predicted grades are same as my AS grade(dropped the B subject). I’m truly upset and feel out of luck of being treated such unfairly, and it cripples me to see some people getting A*s but got lower than me in AS. Is there any chance this could be turned around, so that I’m able to apply for my chosen unis?
Plus I go to a college, where a large number of students head to Oxbridge/other top unis every year.

Hey, you have almost a month to get them turned around if possible. If things don't change maybe re-apply next year with your actual grades if you think you will perform a lot better in the real exams.

Hope I was of some help, good luck.

Is it possible that top unis like imperial will go through adjustment, given that I've achieved like 3A*s in my a levels(I'm saying this because this predicted grades are highly underrepresentative of my capability)
