I thought this product was good but I didn't receive it until right after I took the mcat. I did look at it and everything seemed to be in order and very helpful if you didn't want to make the cards yourself.

Worth the money. An easy to use quick reference of key terms that you can take on-the-go. It won't cover all your study needs, but it does what it was intended to do well.

The person who made the previous post obviously didn't look very hard at the book or try to study with it, or they would have realized that the definitions upside-down beneath the words are NOT the definition to THAT word. This is a long, thin book of flashcards with a vocab word on the Front of the page and the definition on the Back of the same page. The book does go upside down, but this is because there are more words/defs printed upside-down, therefore using the entire page (since the single word/definitions only take up half a page). So the book read right-side up is Bio, and the book held upside down and read normally is half Bio and half Orgo Chem.
Personally, I love my MCAT Bio flipbook and keep it with me at all times. Also, they have the recommended function of bending down/cutting off the corner of a page once you've mastered the word, and have gray corners for this purpose. This is really handy for flipping past words you already know.
I give it an A+. The only reason I was even at this site is that I want to buy the Physical Sciences one now because I love the Bio so much. Handy and helpful.
