I've never used the books you've put in the thread, and unfortunately the links won't open on my phone, so this may be a misinformed idea, but there is a book called Chemistry3 (Chemistry cubed) by Burrows, Holman, Parsons, Pilling and Price (and one other but the name escapes me, I'll add it in an edit when I find it) which essentially covers everything you need to know in First Year Undergrad chemistry, and also contains a fair bit of basic info to help you understand everything fully so it may be of some use to you, but it's more advanced than A-Level
