Yes I am
Edexcel chemistry fo AS? Graham Hill and Andrew Hunt.
I really like it, yes it's not a lot of detail, but it's good for practice questions and basics e.t.c. But I can't find the answers! Some are on the website thingy, but some of them aren't :/ But pointless really!
It is good though, like the way it's split up into little sections and has periodic test yourself questions, they're a little bit repetitive, but then it gets you used to it.
I was going to invest in a better one, I did for Physics, but I haven't had a problem, maybe for A2 I'll consider it.
