Im about to start y11! Need adviceWatch
Try to research deeply into all topics and research for past exams questions online in all your subjects.
And if possible,study ahead of your teacher.
If i was answering a long question in say, Geography or History, i would underline the key work in the question which is telling you what to do, for example, (Describe, Explain, Evaluate, How far do you agree). I only got the hang of exam technique in year 11.
For history i had some really good grade 9 target books which showed me how to answer each type of question for every topic i studied in history.
This is the medicine one for edexcel, but i did crime and punishment. I'm not sure if you can get them for other exam boards.
Exam practice books are good though.
