“Regarding PMP® exam questions found on the Internet. I would suggest against spending any time on them because the quality is uncertain. Example: I found a question that required using Net Present Value to calculate the answer. However, OSP, Mulcahy, and Crowe all state outright that the PMP® exam would not require NPV calculation.”

Charles Ruzin spent about 225-250 hours on his PMP® preparation. He passed with first attempt.

PMP® Preparation

  1. Study materials:
    1. PM PrepCast™
    2. PM Exam Simulator
    3. PM Formulas
    4. Rita Mulcahy’s PMP® Book
    5. PMBOK® Guide guide
    6. Andy Crowe PMP® Book
  2. Watched the PM PrepCast™ first, captured screen shots of relevant diagrams and graphics and pasted them to a digital notebook.
  3. Read Rita’s PMP® Book through engaging reading, exercises, games and quizzes. Began to make sense of PMBOK® Guide.
  4. Created a spreadsheet with the following columns of data: Process Group, Knowledge Area, Knowledge Area Name, Process Name, Inputs, Tools & Techniques, and Outputs. This makes a very good reference for latter steps.


  • The PM PrepCast™ and Rita’s PMP® Book present the material in their own way and this helps students to understand PMBOK® Guide deeper with two different perspectives.
  • The PM Exam Simulator and Rita’s Mock Exam accurately reflected the style and level of difficulty of the real PMP® exam.
  • The PDF of the PMBOK® Guide Guide is very helpful as it is searchable, one can find definitions with ease.
  • Spent time on only quality exam questions as most of the free practice exams found on the internet may contain irrelevant or outdated contents. 
  • Reading the PMBOK® Guide Guide is necessary because there are some “languages” that PMI® wants you to understand fully. Reading the PMBOK® Guide guide it will help you understand project management in PMI®’s way.
