Just quoting in Danny Dorito so she can move the thread if needed
I've just finished CIE A level I definitely recommend: - physicsandmathstutor.com - gceguide.com (for past papers and topical past papers questions - VERY helpful) - gceguide.xyz has e-version of some textbooks and they're all free - znotes.org (for extremely useful notes) I have taken CIE A2 physics, chemistry and biology (maths was Edexcel though). Feel free to pm me if you want to ask any question; I'm happy to help
Yup, I have done my CIE IGCSEs back this summer and I'm currently doing 5 CIE AS-Levels, namely Biology 9700, Chemistry 9701, Computer Science 9608, Mathematics 9709 and Physics 9702.
