AQA GCSE Psychology Textbook...Suggestions?

Hello!
So I am thinking of taking Psychology for AQA GCSE.
INTEREST only, the school offers CIE IGCSE. So I chose this basically because I am ABSOLUTELY interested in this subject.

Yet, I am not sure whether there are tutors in my place that can teach me this subject, so I think I might need to self-study....

1) Is self-studying okay for psychology in AQA GCSE?
2) What textbook(s) do you recommend (especially for the ones who are self-studying)?
I've seen some in Amazon that have quite great ratings and reviews:
a. AQA GCSE Psychology by Karen Boswell (http://www.amazon.co.uk/AQA-GCSE-Psy...pr_product_top)
b. AQA Psychology for GCSE: Understanding Psychology 3rd Edition by Barbara Woods (http://www.amazon.co.uk/AQA-Psycholo...pr_product_top)
c. Psychology: A Complete GCSE Course by Geoffrey Shoesmith (http://www.amazon.co.uk/dp/034098531...oding=UTF8&me=)


THANKS!!!
