# 20 Questions on…

I realised, to my horror, that there was an abject lack of decent A-level maths e-books available for the Kindle, so I set to work putting that right. You have a choice of:

20 Questions on EdExcel Core 1 Maths: a complete overview of the C1 maths course.

20 Questions on EdExcel Core 2 Maths: Logarithms: Everything you need to know about dealing with C2 logs.

20 Questions on EdExcel Core 3 Maths: Trigonometry: All that stuff about $\sin$ and $\cos$ and $\sec$ and what-have-you.

20 Questions on EdExcel Core 4 Maths: Integration: A wide-ranging masterclass, taking you from integrating powers to solving differential equations.

I think your ebooks of 20 Questions on Edexcel C1, C2 and C3 are great!! Any chance they are available on paper or any other form apart from kindle?

Thank you!

Glad you like them, Henry! I don’t have immediate plans for print versions, I’m afraid – but possibly in the future.

Do the e books cover all the topics, e.g. it says that the C2 book is about logs, but does it talk about the other stuff in C2. The guides look great but i just wanted to clarify 🙂

Hi, Sam, thanks for your question!

The Core 1 book covers all of the topics, but the other books focus on one specific topic in each module – so the logs book is just about logs, and the integration book is just about integration. Hope that clears it up

No spam ever, obviously.
