1. PMP® Exam Tip: Get Familiar with the Windows Calculator
As you prepare for your Project Management Professional
(PMP)® Exam, you should know that there are many PMP®
Exam formulas that you will be expected to know. Among
them are Earned Value, PERT, communications channel and
about 40 others you must have memorized.
Since these formulas must be in your head, you will not be
allowed to bring your own personal calculator into the exam
room with you because it could have some of the formulas
saved with it.
However, some of the calculations you will be required to
complete are likely to be complex enough that they will
require the use of a calculator. So during the exam, you will
have to use the Microsoft Windows-based calculator.
It’s important for you to be prepared for all facets of your PMP® Exam, and being comfortable
with the Windows calculator should be included in your preparation.
That’s why after learning that they will not be allowed to bring their own calculator into the
exam room, most people simply stop using their hand-held calculators and fire up the Windows
calculator every time they are faced with a formula in a sample question. I recommend that you
do the same.
And here is my most surprising recommendation: use the calculator for every single calculation
you have to make: 100 divided by 2? Use the calculator. 3 times 10? Use the calculator.
The reason for this is simple: Taking an exam is stressful and it’s easy to make a silly mistake in
your head. And we don’t want 100 divided by 2 to suddenly to be 200. So use the calculator.
Passing your PMP® Exam is too important to your future. It will be stressful and you may
struggle to have enough time to finish it. It only makes sense to use all of the tools you have at
your disposal to make it as easy as possible. This includes being prepared to use the Windows
based calculator.
