There are various PMP workshop conducting organization in India, a known name you have provided in your query. The basic motive why people choose these REP’s is that they want clean 35 hours PDU and no other reason. I am not sure what is the reason you are opting for.

I am also a PMP workshop training instructor and here is what I feel honestly:

1. The PMP workshop does NOT really prepare you for PMP exam, majority of the things will go bouncer (out of your head) when you hear for the first time.

2. However, since these REP’s have certified PMP experts you will learn many things about PMP, its process, its audit process, free structure, form fill up etc.

3. The direction that you would get in these workshops will help you to plan your study, keep in mind, you have to make a plan to pass PMP exam, if you continue accepting various tips on forum, you will fail most likely.

4. After the workshop, make a lesson learn and firm plan and stick to it, Give ample time like 3-4 months of regressions preparations and attempt about 2000 PMP mock questions.

To pass PMP you need these KRA’s:

1.       Basic project management practical knowledge and experience

2.       PMBOK IITO concepts

3.       Common sense

4.       Ability to face the actual PMP exam (fearless and patience)

The point 1 and 2, you will get like 20% in these workshops, and all other things you will have to do yourself as per your PLAN.

Hope this helps! All the best for PMP.
