If you already have the 9th edition, save your money. Examkrackers likes to give its test-taking strategies but at the end of the day, books are only good for cramming that information into your head. Anything in the book, whether or not they tell you to focus on it, you should know like the back of your hand. Test-taking strategies are best learned through experience such as taking the official AAMC material or through private tutors. It's very difficult to teach techniques through books so any attempt any book tries at teaching technique, it's like learning to do surgery because you read Wikipedia. If you need a reference for a good, inexpensive private tutor in the NY area or through videochat, PM me.
