Guys, I was going thru a few MOCK exams and suddenly I found that  I was kind of confused or probably my concepts were not clear for the 2 ways to make a PDM. I refered to Rita and it shows 0 method. However everywhere else is 1 method. Thanks I relaized it before actual exam. And this was making to hell lot of diff. in the answers. Thought of sharing with everyone on this forum.

Having learnt this, 

Is there any place I can drill the PDM and critical path questions more ?? to check if I am good now ?

Thanks !
