There's thousands of students such as myself who put in hours of work every day to achieve these sort of grades (AAAB at AS, predicted AAAA at A2 ((didn't drop a subject)), and you expect to go from Es to A*s with little effort?
If you can't be bothered to do the work you don't deserve the grades, simple as. Especially not if you're not going to do the work at uni either.
There's not a quick fix to get good grades, the only option is to get your act together and start working hard.
