I've been researching USC's MA in Strategic Public Relations and am wondering, what is the difference between that degree and the MA in Communication Management? So far, the differences I see are: The MA in SPR requires 6 courses, the MA in CM requires 3; SPR is 40 units, CM is 36; Not sure how many units can be taken outside of Annenberg with SPR, 8 can come from other depts with CM. Can anyone offer some clarity of what are the hard differences between these two programs? Is one more rigorous than the other? Any guidance would be much appreciated.
