Major mistakes on formulas and PMBOK interpretations
I tried the app and and apart from the list of formulas; it turned out a major disappointment.
First off ... It doesnt contain 1000+ questions as stated.
Second; all formulas implementation is WRONG (ex: project selection based on NVP uses wrong made up concept not related to pmbok. It mixes up six sigma (+/-6) with time estimates, SD and Pert formulas where in app they used the value +/-6 as a factor of the standard deviation in days Which is wrong!)
Third; Lots of references for the given answers does not relate to PMBOK at all!
Forth; this can go endlessly
Do not waste your money. (I have screenshots of the above errors saved for reference if/when needed)
