For the PMP exam, you must know how to correctly answer questions with formulas about earned value management , communication Channels, procurement Contracts , Expected monetary value , Network diagrams and critical path , project selection methods ,  and some mathematical basics in regards of project management , now it’s the time to revisit the following topics, memorize their formulas for the exam and practice some tough questions:

1. Project Selection Methods : Present Value , Net Present Value , Cost Benefit Analysis & Payback Period
2. Activity Cost & Duration Estimates: Simple Average, Weighted Average, Standard Deviation and activity range of estimate .
3. Critical Path Method: Early Start, Early Finish, Late Start and Late finish , Float calculations , Critical path determination .
4. Earned Value Management: Cost and Schedule Variances , Cost and Schedule Performance Indexes , the 4 formulas of Estimate at Completion , Estimate to Complete , To Complete performance Index and Variance at completion .
5. Numerical Risk Analysis: Expected Monetary Value , Decision Tree analysis , Contingency Reserve Calculations .
6. Communication Channels : Communication Channels Formula
7. Contracts Management: Make/Buy Analysis ,Contract fees and Profit , point of total assumption .

You will see different question models testing your knowledge in the PMP Math Formulas , questions that are straightforward where you are given values and you are expected to apply the correct formula , in such type you will get a set of values and asked to calculate a result. another type of math questions where it  looks as if you can simply apply one formula. But as you are applying this first formula you suddenly realize that one value is missing. This missing value must then first be calculated via a second formula , so in such type of questions you need to apply two formulas , In some type of questions you need to invert the formulas , For instance instead of asking “2+8=?” the question would be “2+?=10” and it is your job to invert the formula and calculate “10-2=8 . Specially for the earned value management questions you will be given the result of the formula ( Eg : Cost & Schedule Variance ) and you will be asked “ What does this result mean for the project?” , one of the complex questions you will see for the Estimate at Completion is to select the right formula you need to use in the scenario described in the question , also you will see questions testing your knowledge in the definition of each formula , it’s not only about memorizing the formula were numbers need to be inserted , you need to understand the definition of each formula !

What’s my advise ? Practice , Practice , Practice !

Below am listing the important 22 formulas you need to MEMORIZE for the exam !

Practice Math Questions as much as possible , you can guarantee 15 % or more of the exam questions , expect to see around 12-15 questions only on the Earned Value management Calculations ,

I have prepared a course on Udemy platform which was above the students expectations with more than 250 students enrolled and a rating of 4.7 , it contains 4.5 hours of recorded videos , going through each of the 7 topics i mentioned above and all math formulas included , In this course I will be solving with you 50+ tough math exam questions , I highly recommend this course to master the PMP math topics and formulas , you can enroll through the link here for a price of 19.99\$ only ,

If you are welling to pass the PMP exam from your first attempt , this is a topic you cannot ignore ! as i mentioned earlier , the PMP math questions will have a share of around 30 questions , you need to memorize and understand all math formulas required , for a comprehensive explanation of the PMP math concepts and questions , you can enroll for my PMP detailed math concepts .

Once you feel you are ready and mastered the PMP math concepts , you can test your self through the 150 tough math questions here .
