So I just started my A Levels after doing well at GCSE. My subjects are Bio, Chem, Geog, and Economics (AS). When studying for my GCSEs I just used the CGP textbook for all of my science exams and just wrote notes from it which I memorised weeks/days before the exam and I did a lot of past papers. Can I use this technique for A Level Science too? As in, just using the CGP textbook and writing notes to memorise, and then do past papers. Or are the CGP books too vague for A Levels? I really don't want to use different textbooks because they have like 250 pages and I can't write and memorise that many notes. Plus, any other differences between revising for A Levels compared to GCSEs? Apart from revising way more.
Thanks
