How to attain good marks in the OCR 21st C exams on 6 mark questions.
I did ocr 21st century last year and got all A*s. Basically, there are only certain six markers they ask you- for example in C4 they often ask about Mendeleev. You need to do all the past papers to learn these. Another one they like to do is comparing diamond and silicon dioxide. Look at the markschemes to know what you need to put.

The trickiest ones are the evaluating data questions. You just need to learn how they want you to answer these, they don't test your scientific ability at all.

Any questions just ask.
