This book is a must if you feel you need extra help with the chemistry a-level, i was not confident at all about the as exam but so far i got an A in the jan exam and am feeling confident about the results from the second one!
The book explains the key points you need to know with just enough information to make it understandable without being too much for revising from, its easy to make notes from and then test yourself with well structured and exam-like questions after each topic so you can see how your doing
All in all a well structured book that is defiantely worth a buy, at the least it will boost your confidence before the exam and if used correctly will definately boost your grades!!!
The only fault i have with this book is i think a few more illustrations of equipment, eg for titrations, reflux ect could have been helpful which is why it gets 4/5 stars from me!
