Sounds just like me at 16. Wasn't very motivated despite studying the A-Levels I wanted to (Maths, Physics, Computing). Spent all my spare time stealing Internet access at the local University (this was back in 1992/1993). I got decent grades (AAB) and got into my first choice University, but the motivation to do well still wasn't there. Ended up getting a 2:2 where everyone expected me to get a 1st. After that I was lucky and ended up in a good job where degree result didn't matter.

Looking back I wish I'd talked to someone (not my parents) about it at the time. So I'd recommend finding someone to talk to at your college; your form tutor (depends, I didn't get on with mine), careers advisor, pastoral care reps, etc. Just remember that they should be there to help you do your best, not bollock you for not putting your full effort in.
