I passed my PMP exam in the year 2005. In those days, the PMBOK Guide was much thinner than it is today. It was about one-fourth the size of today's version but it essentially had the same Mathematical concepts.

If you believe that the explanation of Mathematical concepts is not good in the PMBOK Guide then think of the plight of students in those days.

When I took the exam, there was hardly any PMP preparation material. At that time, the students could have only wished for quizzes or mock tests. There were no simulators or reference books covering Mathematical topics in detail. To make the matters worse, the Internet was in its infancy and there were no additional study material.

Back in 2005, I was afraid of Mathematical Questions. All the formulas essentially looked the same. Initially, I could not figure out which formula had to be applied where.

I had many anxious moments while preparing for the Exam but, ultimately, I overcame all odds to pass the exam with flying colors. The best part is that I did not memorize any of the formulas.

So, how did I prepare?

While studying, I went through the Mathematical concepts many times over till I understood them well.

I practiced questions and then practiced some more...

Things have changed since then.

I became a full time trainer and coach in the year 2008. As an independent trainer, I wanted to provide the best study material to my students. So, I created a PMP Mathematical Quiz.

That Quiz has been refined over the last few years as the exam changed. You can take this Quiz to validate your learning and knowledge of the Formulas before taking the actual exam.

Over the years, I have received positive feedback from my students about the ITTO Quiz. It has given confidence to hundreds of students to successfully pass the PMP exam.

Memorizing formulas doesn't work in Mathematics. Practice a lot of questions to gain confidence.
