Hello,

I am in my final preparation for PMP.

I have a question regarding critical path in PMP exam.

I have seen on different ressources two ways to calculate early start and early finish.

Some saying that early start = early finish of previous task

Other saying  early start = early finish of previous task +1

At the end you have these two results with :

task A 5 days and task B 3 days, B following A

=> If  early start = early finish of previous task

task A ES=0 EF =5
