Hi Zwangsstörung,

Do you know the exam board for that GCSE? E.g. OCR, AQA etc? Find out, and try and get a hold of past exam papers. I think doing past exam papers is extremely helpful, so definitely look into that.

Also, back when I was in school, I found that when I was very open-minded and analytical in exams and essays, I got good marks. What I mean by that is you should make your answers very well-rounded, and not just one-sided. Look at things from different perspectives and give detailed pros and cons of these perspectives. It shows the examiner that you know your stuff.
