OP: I remember being in precisely your position when my last year's exams came around many years ago. I remember going from effortlessly succeeding in school to busting my ass to be mediocre in uni, too.

The fact is that over the long run, effort counts for more than exam performance, so if you are trying, keep doing it. That's what counts. ADD/ADHD-type inability to concentrate and focus are hard, but you do learn to cope, and more importantly you learn to position yourself in situations where you exploit its advantages.

What I wouldn't do is not push yourself when you believe you can get away with it, a mistake you and I both have made. Keep yourself on the boundary of uncomfortable, otherwise you will not be prepared when it gets tough.

Keep it up for a few more weeks and it'll be done, and just keep getting up.
