P1 and M1 books?

[Zishi]

Hello, I've recently finished practicing the books of P1 and M1 endorsed by Cambridge. I want more books for p1 and m1 to be suggested so that I can do more practice.

The books published by Cambridge are more than enough.
I would suggest heading towards past papers directly.

However if you don't intend to do so, 'Understanding Pure Mathematics' by 'A.J.Sadler' is a wonderful book.

Oh, thanks! I've already solved many past papers of them and they're VERY easy...so I thought that I should do more challenging question. Anyways, thank you!
