DS is sitting Computer Science in the summer (OCR). He is fine with paper 1 but is really struggling with Paper 2. We have all the OCR books, exam papers etc but I think we need to go right back to basics with algorithms / programming / computational thinking. Are there any other books or resources we can buy to start from scratch?
Unfortunately it's the one subject that DH and I have no experience of (my CS GCSE was 30+ years ago). His teacher was off before half term and I think will still be off next week so there's no one to ask at the minute.
