Two of my peers who’ve more than 15 years from it experience in the banking industry so when a project manager for nearly five years appeared for your PMP certification exam last week. They said these people took a PMP Prep course from your registered PMI schooling provider and prepared well for the exam. However, still they were not able to pass the exam. Like them, several hundreds associated with project managers who appear for the exam fail to give their first attempt.

As we all know the Project Management Institute (PMI) may be the leader and one of the most widely recognized organization in promoting project management guidelines. It was created in 1969 and also started offering the Project Management Professional (PMP) test and Certified Associate in Project Management (CAPM) accreditations in 1984. Many jobs need the candidate to own completed the PMP test.

There are many reasons why candidates fail in the exam. The most common reasons are:

They have the shallow understanding and don’t study deeply: This is just about the most common reasons why candidate fail to pass on their own first attempt. Both practical as well as theoretical knowledge is required for one to pass the exam in the first attempt alone.

Solution: I would suggest the exam takers to see PMBOK Guide most recent version from cover to pay for at least three times. You will end up being easily answering several questions should you read the Appendix areas from page 345 to 455. Concentrating more upon Appendix section G (interpersonal skills) would help you to answer lot of behavioral oriented questions on the exam.

They fail to read all answers: This is another mistake the majority of the exam takers carry out. They look at the given options sequentially of course, if they think the option 1 or 2 is right, they skip the other options.

Solution: Read questions and given answers very carefully. Re-read all questions containing negative words for example “not” “least” or perhaps “except”. Likewise check for those qualifying words: “all”, “most”, ‘some’, “none” and keywords for instance input, output, tools and project management method. Since the exam is four hours you have enough time to go through all the provided four options.

They do not really think PMBOK is definitely right: Let me offer a simple example here. Below is an example exam question for your reference

Phase exits, stage gates or even kill points are typical terms for: a. GO/No meeting w. Project closure standards c. Kickoff for next phase d. Phase end evaluations

The right selection is “D”. Even though your company may use different method of assessing the project phases and different terminologies for procedures, the PMBOK claims before closing a project or a phase the director should contact Phase-end reviews.

Solution: When you are taking the exam you have to think PMBOK Guide is obviously right and so that you can pass the exam, we need to utilize the right Key term phases used in PMBOK Guide regardless of whatever you perform today to manager assembling your project.

As some associated with may know already, PMP candidates are restricted to three exam attempts inside a year. If they fail 3 times within one year, they will need to wait one a lot more year before submitting their application form. Hence, focus on the particular passing the pmp certification exam the very first time. Anonymous survey results show that under 50% exam individuals actually pass the exam on their first attempt and I’m pretty sure you can pass it in the first attempt should you avoid the mistakes highlighted here.
