A-level students: forget about it, enjoy the "summer" (if we ever get it). It's out of your hands now.
For those of you applying to Uni, and think you haven't got on the course you want to go on. Look for back ups now, even contact those Unis (so you get your name around). Just be honest about it- I think I'm not going to get into my choices, would you consider me. If you don't think you'll get on any courses to do with your subject. Again think now about what you'd like to do. The worst students are those who fail on A-level day, panic, cry, look on UCAS clearing and choose a course before somebody else takes it. DON'T do this as you could end up in a course you don't really like just because you panicked. So do some research now, I know one or two who panicked and I think they now regret doing their degree (and this is purely because of what happened in those hours on results day).
Those of you who are quite confident. What I did was look at the UCAS website early in the morning to check if I got on the course. Fortunately I did, so by the time I left for school, I wasn't nervous at all - I knew I had done fairly well.
Finally - if you're offered to take a picture in the paper, DO IT- it's great to look back on. And also thank your favourite teachers if they around - it may help you in the future.
