Hi could any of you who own this textbook have a quick look and explain why in the contents pages it says 'Section B Optional topics student course notes and support materials' (at the bottom left hand side of the 2nd contents page) but has no page number and is no where to be found in the textbook? Is there something wrong with mine or am I not looking in the right place?

I think it is just saying that part B of unit 5 is the optional topic. The Nelson Thornes textbook doesn't cover any of the optional topics.

you're referring to this book? http://www.amazon.co.uk/AQA-Physics-.../dp/0748782818

well if so, it doesn't have section B optional units, aqa just didn't bother putting them in for some reason
