- Pay attention in class, don't be afraid to ask questions or get things wrong - your teacher is there to help. Also connected to this, be attentive and don't talk to your friends etc. Of course DONT SKIP LESSONS, you're the only one that loses out.
- Do you're homework properly (sit down in the library or at home - not on the bus of 5 minutes before), it really does help store knowledge and reinforce areas you are weak at.
- Revise properly and in time - start at least 4 weeks before you're exams and cover everything needed.
- DO PAST PAPERS! Understanding the mark schemes are one of the biggest factors in anybodies results.
That is pretty much exactly what I changed, and I managed to improve from BBC to AAB. To achieve good grades, you needn't go over and above the required level, you simply have to do what is required of you! I know so many people who did badly, these were the people that didn't go to lessons or do homework, and the people that went out every Thursday and Saturday and got drunk and thought they were the cool kids.
Who will be the cool kids in 20 years time, I say!
