Obviously you've sent it off now, but you didn't have to specifically write your module grades, your teachers should have acknowledged if you were a couple of UMS marks off and should have written this in your reference to strengthen your application. I achieved a disappointing ABBC at AS and my predictions are A*AAB as I was 2% off the next grade in all my 4 subjects and my teachers included it in my references along with other achievements I gained (e.g. A's in all coursework for bio and chem etc). I'm applying to universities with requirements of AAB-ABB
