Example 1: You are the project manager for a workout app development project, The Actual Cost of the project is $1000, the planned value is $1,200, and the Earned Value is $900. The project was budgeted for $2,000. What is the Estimate to Complete (ETC) assuming that the spending continues at the same rate?
Answer: Since the spending rate continues in the same rate, then we use the following formulas to calculate ETC and CPI. ETC = EAC -AC In this example CPI = EV/ AC since the spending rate remains constant. CPI = $900/$1000, or 0.9 EAC = BAC/ CPI EAC = $2,000/ 0.9, or $2,222 ETC = $2222 -$1,100 ETC = $1,122.
Where did 1,100 for AC come from? AC was $1000 from the example question.

On the whole quite a good book.
HOWEVER, I am sorely disappointed by the author and the editorial team, as there are SO MANY MISTAKES in the text, starting with formulae, the worked examples and then in the worked answers to the exercise questions.
Rod C. should be ashamed of himself to publish a text book in this state of dis-repair.
This book is so ridden with errors, it is unbelievable. Example: in a CPIF calculation question, it lists a target fee of $10K but after you work the problem, you cannot find a multiple choice answer to support your answer. Well when you go to the answer key and see how they worked the problem, you then discover that they used $15K as the target fee without giving you any justification leaving you to believe that it is a huge typo/error! There are dozens of these throughout this book. I kid you not. Rent it for free on Amazon Kindle Unlimited and check it out. You can get a 30 day free trial of Amazon Kindle Unlimited.
However, if you can get past these goofy errors, this book can have some value. But it is frustrating that you have errors like this throughout the book. I think this is sad as this book has serious potential! I am wondering if this book were written overseas and there were some translation issues but am not sure how that could lead to such blatant errors.
I believe by using this book, you'll increase your score on the PMP Exam, not to mention you'll be a better project manager, equipped with the math tools and skills to manage your schedules, costs and contracts on your project.
The questions are very good. They range from fairly easy to quite challenging, but not too much of either. It's a good mix. Explanations are clear and easy to understand. The book has very good content. This is a really good mathematical supplement to the PMBOK and Rita's Exam prep material.
I highly recommend buying this book and doing as many of the questions as you can. Especially the EVM, Time & Schedule, Contract and Communication Channel questions. Doing these sets of questions will probably gain you at least 15 - 20 more questions right on the exam. Think about it, that's a big jump. It could mean the difference between a BP and a MP, a MP or a P, a pass or fail.
Buy the book, it's a winner. And best of luck to all PMP Aspirants!
