When buying GCSE CGP guides, is it better to buy the CGP guide for your exam board or just for that subject in general. For example, for biology my exam board is OCR, so should i buy the CGP guide for the OCR exam board or should i just get the guide for biology in general? (so doesn't say and exam board on it).
I would recommend buying the one for your exam board as its more detail-specific. I bought all 3 CGP guides for my AQA exam board. Not sure how the general book is!!
