Thread regarding University of Phoenix layoffs

Another reason to expect more cost cutting in the future--it helps the short-term bottom line. Can anyone tell me how University of Phoenix cut instruction expenses by 19%? Are they increasing online class sizes in their online classes?....."The secret behind Apollo's surprise has to do with cost-cutting in two major categories: instruction and admissions advisory. While revenue might have fallen 15%, Apollo was able to cut spending in these two departments by 19% and 31%, respectively. The cut in instruction was particularly important, as it accounted for roughly half of all expenses last year."........http://www.fool.com/investing/general/2013/10/23/keep-apollo-groups-pop-in-perspective.aspx
