I only used this one tiny revision guide for my first AS Chemistry exam and got an A. I'd strongly recommend for anyone and everyone taking science at A levels. revision guides are very personal, but this is by far my favourite!
It's the best revision guide I have ever used. Explains everything you need for the exam and gives you examiners' tips which are highly useful. I personally only used this book and past papers and managed to get an A :)
Keeps the drink hot for long. The lid is very comfortable to drink from. The only drawback is that the inside of the cup isn't as large as I thought it would be, so doesn't fit as much tea as I'd like it to.
