It didn't fit at all, even after ordering a size bigger and I'm a size 8. I am very annoyed with the suppliers seeing as it said I could return it until the 27th of November, so when I tried to return it a few weeks before that it said I couldn't. I was not happy at all, I am furious. Won't be using them ever again.
I would recommend this product particularly to visual learners of AS psychology. It is great value for money and is definitely worth buying, especially if you are after a more simplified content of the course to revise from.
