<p>For AP euro, get Viault’s Modern European History-it covers everything in a nutshell, and unlike some prep books, it have moderate coverage of almost everything you need to know. don’t know about the other books, sorry.</p>
<p>AP Euro: “Modern European History” by Viault. Hands down.
AP Chem: I liked Princeton Review because it was a nice quick review of concepts that I could use along with my book (“Chemistry, 6th ed.” by Zumdahl) – it’s good to start using this during late March or early April. ARCO is good for getting a secondary explanation on a concept, but it’s not really a practical “cram book,” because it has way too much information.</p>
