I highly recommend you to buy this book.,
This review is from: Edexcel Physics for AS (Advanced Physics for Edexcel Series) (Paperback)
(I have bought this on amazon using a different account, but I signed up with Google and I didn't trust them with my card details)
If you want to get an A in physics then you should buy this book. It was publicly appraised by edexcel, and looking through this book I know why. The content is absolutely amazing and provides detailed information on every topic.
But me personally, I would get another revision guide to give you a more simple approach because there is lots and lots of writing.
There aren't many negatives. It's difficult to criticise this book.
I highly recommend this book but I also recommend buying a different revision guide. I say this because when I first started my course I was scared of the fact that there's so much information I need to learn. But honestly, not every single thing will come up. So get a book that shows a simple approach. But still use this because this is definitely the most detailed book.
For example this boon provides information on base and si units, but my other 2 revision guides do not.
