I took the PMP Exam Prep Course this week from Project Management Academy. I went into it expecting to get a painful week of drudgery which would help me pass the test but not necessarily teach me anything I would use in my job. What I got instead was a class by instructor Michael Bergman which was perfectly paced and really helped me gain an understanding of the subject matter. The course material is a great supplement to the PMBOK manual from PMI.org. I have not yet taken the PMP test, but my practice tests are showing that this course did its job in preparing me to pass it.
Without hesitation, I would recommend Michael and PMA for anyone looking to prepare for a project management certification.
