Is cgp books,cognito and save my exams everything I need to cover the full specification in detail?
Those should cover the whole specification but we kinda need to know if you’re using this to revise and supplement in-class learning or for self-studying the content. Apart from CGP textbooks, most of those are largely revision resources so great if you’re revising/ supplementing and consolidating with them. If you’re self-studying, then I imagine they’d still be enough to cover everything but someone else on here might have a better idea of if they provide enough detail.
