 Subhajit Palit Topic Author Offline Fresh Boarder Posts: 8 Thank you received: 0 Hi, I think I can rephrase it like below:- Free Float = ES of Following - ES of Present - DUR of Present as Free Float = ES of Following - EF of Present as [ ES of Present + DUR of Present ] = EF of Present What do you think ?

 Michael DeCicco Offline Expert Boarder Posts: 130 Karma: 3 Thank you received: 34 Subhajit, in general I highly recommend memorizing the formulas as they are in the PMBOK. The entire study regimen for the exam is based on a logical progression of a methodology. This includes the consistency of the formulas as you find them in the various study guides.
