I purchased this book because it states the 'bonus cd' is Mac compatible. There are better books out there, as far as the review, but I must have one with a Mac compatible cd because I have to turn in proof that I have answered 1000 NCLEX questions with an overage of 85% or better during my last semester of nursing school (I want to have this done before the semester starts in Jan. 2011). I would have bought a different review book but this is the only one I could find that stated the cd would work with my Mac. Once I opened the cd envelope, I could not return the book. I did not purchase the book from Amazon but wish I had because Amazon would have let me return it for a refund!
