The materials were very well put together. I am concerned however that i couldnt find alot of the formulas in the PMBOK edition 4, so are wondering how current the material is?
[Editor's response: All our PMP Exam Prep materials are 100% updated for the most current version of the PMP Exam. The reason why you cannot find the formulas in the PMBOK Guide is that only about 75% of the exam is directly related to the Guide. The rest of the material comes from various other sources. Rest assured that these formulas have been well researched and are the ones you may encounter on the exam.]
