Hi!
For the Exam, is Duration calculated as

EF-ES = Duration or
EF-ES +1 = Duration?
I used #1 on a trial test question and got it wrong. I see it both ways in various presentations and learning tools.

Maryann,

It depends on the method used to create the network diagram. Check out Cornelius' response here:
