Well I proved it; it is possible to get an A in a physics extended essay: I know that I am a physics teacher and I"ve written a couple of books but I haven"t written an essay since I was at university. So here are my 10 tips: 1. Make sure you have a good research question. 2. Don"t be too ambitious. 3. Make a plan. 4. If you have no idea how you will do the practical then think of another research question.
