  • One-stop shop for all the formulas that you need to know for the PMP Exam. You don't need to scavenge for information from various books, websites and other resources.
  • The sample exam is the highlight of this product. The answers are explained very clearly.
  • Helps you reduce your exam preparation time by providing you all the formulas in a single package. It would certainly come handy during the last few days before the exam.
  • Some topics which aren't covered well in the popular exam prep books, are covered well in this guide. Examples include Cost Estimation, Project Selection and Procurement related formulas.
  • The guide covers the full breadth of formulas for the PMP exam. It will help you get a solid base in numerical based questions and a clear edge in the exam. Numerical related questions are sure-shot scoring areas. They have only one correct (and unambiguous) answer. If you know the formulas well, you can really increase your chances of success in the exam.
  • Very accurate and reliable source of information.


  • From the name - "PMP Formula Study Guide" - it sounds like a single "thick" study guide. However, the main "study guide" is just a quick reference guide for formulas. The actual meat lies in the email course and the sample exams. I feel that the email course should have been integrated into the main "study guide" to make it into a single comprehensive package.
  • In continuation to what I mentioned above, I liked the content of the email course but I didn't like the idea of an email course itself. I would rather prefer to get all the information in a single PDF file.
  • Hardly any graphics or diagrams (except for Network diagrams, of course). Many topics are better understood with visuals.
  • The information in the "study guide" is presented in a tabular format. The layout looks a bit crampy.


PMP Formula Study Guide is a reasonably priced, unique product that addresses a very crucial aspect of PMP exam - the formulas. Though it does not provide any information which you cannot get for free on the internet, the value comes from having all the accurate (formula related) information, from an authentic source, in a neat little package. It pretty much covers all the formulas that you need to learn for the exam and can save you tens of hours of valuable exam preparation time. Despite a few shortcomings in the packaging of the content, at $29.99, I would call it a good value for money. My rating: 8 out of 10.


4.0 / 5.0
