-How rubbish the mechanics teacher at our school is.
-Screw what seem like good subjects, just pick what you're actually good at.
-Get ICT coursework out of the way at the START of the year. You get too much less than your capable of when you do it at the last minute.
-Keep track of where your text books are. You miss a few words in your notes, it can make them ambiguous, which isn't good.
-Make agreements with your friends in the classes to keep each other concentrating on the work. Me and a friend did this at A2 after messing up AS, it's amazing how much it helped!
-Actually stick to all the things you say you're going to do. You let one tiny bit slip, and it all falls with it and you end up procrastinating, doing the bare minimum, and just not really getting what you should be out of it.
-Keep thinking about Uni. Look at the ones you want to go to early. It's a huge motivator to end up at a Uni you really like.
