Hi Folks,

I had gone through EV question from couple of books:

1)Headfirst where EAC formula is BAC/CPI.

However in pmpprep cast the formula for EAC are categorised as below

EAC'typical'= AC+((BAC-EV)/CPI) and another one is 

EAC'attypical'= AC+BAC-EV

EAC'no variance'= BAC/CPI

EAC'fundamentally flawed'=AC+ETC

Similarly for ETC'atypical'= BAC-EV

ETC'typical'=(BAC-EV)/CPI
