My issue is that it was NOT clear from their product description here online that the 200 questions in here are a SUBSET of the ones in the software. This little factoid is noted on the very bottom of the first page of the book. Now, if you are not planning to buy the software, spending this kind of money for 1/7 of the questions is not a bad deal. However, if you had already bought or are buying the software as part of your exam prep plan, you will be wasting your money to buy this too. I wish I'd known before writing my name inside. I should have saved the money - hopefully I'll help you.
If you are NOT buying the software, but do have Rita's study guide, this little book is useful, because it does cross-reference the pages you need for clarification. If you miss a question, you can easily research your areas of weakness. So for this market segment (non-software buyers) this is a useful, worthwhile tool.
Portability - about the size of a stack 3/8" high of 3 x 5 cards.
