another predicted grades problem

Applying with predicted grades below the stated entry requirements to prestigious universities is wasting a choice. You can apply through clearing although that is very complex and places are very limited, if available to begin with, so clearing is probably best avoided. You could just apply with achieved grades, which would boost your chances of success tremendously as long as you meet the stated entry requirements, or you could talk to your school again to try to move your predicted grades. They won't up your predicted just because you asked nicely, but they might up your predicted if you make a deal with them in which you'll show improvement in your grades and/or do extra homework or anything you can think of. After all, the deadline is January. Not that I'd reccomend applying in January but you have plenty of time even in the next school year to show your college you have got what it takes to get that A!
