"Worth every penny!"
You will improve everytime you solve problems on this book. Very solid contents with passages that are really going to help you on the MCAT. Although I think they are harder than the real MCAT problems (some questions are vague) you will learn alot by doing it rather than reading it.

"Great MCAT Bio review"
If you have the time to go through 1001 questions, then this is the book you're looking for to prepare for the MCAT Bio section. What I liked about it is that it contains both passages-based and discrete questions. In fact, I'd recommend all the 1001 Examkrackers books.

"A great find"
This book is by far the best in terms of MCAT biology prep. Other companies overwhelm readers with facts and irrelevant information, while Examkrackers gives you what you need to know, and provides you with "1001 questions" in MCAT passage-style form to ensure that you know more than just the science: you also know how to take the MCAT.

There are a few errors in the book, but to be honest, they are small and obvious; there is no confusion about correct answers etc. Such is the reasoning for my awarding 4 instead of 5 stars.

"CRAPTASTIC!!!"
I used the entire book for MCAT preparation. I took the MCAT. The questions in this book were NOTHING like the MCAT. Don't waste your money on this book. More importantly, don't waste your time on this book.

"Extensive coverage... but full of errors."
I bought this book looking for a good passage-based practice for the biology section of the MCAT. From my experience with the book 101 passages in Verbal Reasoning, I was impressed with Examkracker's accurate represenation of real MCAT questions. However, I soon found numerous errors in the questions used in this book, and I confirmed that they were wrong with several physiology and biology professors. From that point, I gave up on the book, because it caused more harm than good.
