Oh hahaha lucky! I'd be a lot better off if I had done coursework. No I'm just doing paper 11, 31 and 61 I think.
Oh right, yeah that's quite tricky.
No basically what I do is just search for the topic + IGCSE, so for example "Eye structure and accommodation IGCSE" and there are usually some good videos. Only bad thing is that they usually go through a bit too much (since it's usually GCSE Biology vids) but it's good enough.
