I'm going to be starting college this September and two out of the four A-levels that I will be taking are Biology and Chemistry. For GCSE Core and Additonal science I sat my exam board with AQA and I was wondering if It would be better for me to sit my A level sciences with the same exam board rather than with different exam boards? Does it make a difference which exam board you sit your exam with? For example many people say OCR salters for Chemistry is dreadful. How was your experience with the exam board that you sat A level Biology and Chemistry with and what would your advice be?
