Query: CAPM The Easy Way

I was very impressed by the book - especially its question and solution format. Having a reference into the PMBOK for each question was very helpful and helped me a ton when I got a question wrong. I also found the solution layout to be very instructional in that it not only told me why my answer was right or wrong but also told me why other very plausible distractors were not completely right. Very helpful.
