There are VERY few errors; they're usually just poorly worded questions/answers/explanations.
You must have a later edition than mine, because there were things that were flat out wrong in my books. And their explanations are often so short that they are worthless. Even if it's a trick question and they are right, they don't explain the trick. That's what irked me more than anything. I guess some of that could be blamed on ambiguous wording, but wouldn't they fix that after all of these editions? I just get the feeling they wrote it once and didn't take the time to edit it. Plus, while their bio textbook is really good, I thought the 1001 questions were not very helpful for the MCAT I took.
Thanks! Thought Amazon ripped me off there.I believe it's 2006.
Edit: I take that back. It's 2004: http://www.amazon.com/Examkrackers-...0162569?ie=UTF8&s=books&qid=1184864438&sr=1-3
