Well, I got an email response about this issue a few minutes ago and the CIS-633 would count for both the Masters and the Certificate. So, I can make my concentration something other than PM, and then take 2 extra classes and get the PM Certificate. Sure it is 2 extra classes but it is almost like having 2 concentrations since the only difference in the Certificate and the Concentration is that the Concentration requires 4 of the 4 PM courses while the Certificate requires 3 of 4. I'm not sure I am going to go this route but I am going to strongly consider it.
