It is hard to tell whether UMW masters have good placement among US PhD programs since this MSc was initiated just 2 years ago and no graduates are recorded yet. In many cases a department offers different courses to master and PhD candidates( PhD courses are tougher, of course), and I am not sure if UMW provides PhD- level courses to MSc program, just as BGSE does. If not, maybe the exemption cannot be done.
BTW, I was also admitted to BGSE and hopefully I will go there.
