PMP Certification: What is the correct critical path on this diagram?

Please take a look at this imageand help me understand what the correct sequence is for the critical path. I assume that the numbers in this image correspond to duration.

My understanding is that the critical path consists of the path that adds up to the longest duration, but the program says that is not correct.

Thanks in advance!

Start(0) -> B(3) + C(2) + D(6) + F(5) + I(3) + J(3) -> Finish(22)

What did you get?

That worked, thanks! I think I had come up with this solution, except I didn’t click the Start and End boxes and so it came back as being wrong. Appreciate your help on this.

So as a project manager, your job is to figure out the maximum number of man-hours you can bill to your client? :stuck_out_tongue:
