Which is better and Why ???

[~ Miss Relina ~]

I do not have first-hand experience with Edexcel Math, but I have read around the forum and heard, in general, that CIE A-Level Math is more difficult. When it comes to just CIE, my experience is that P1 is pretty simple, while P3 drains the blood out of you. Depending on which other papers you appear in, they could be better/worse; S1 is sweet, M1 seemed very easy but gave me a hard time in the finals. In general, A-Level Math was a demanding subject but not something that could not be maneuvered. Good luck in your studies!

Thanks
