And i think it is silly not to...

people may not want to admit it, but with a college degree and education, one not only gains knowledge and profession, but also it puts one into a different social class. Classes exist even if liberal media tells you otherwise, or at least "people in a certain class" may not announce it openly, but will look at one's back ground before letting one in. like it or not. I want Med to go to the top.
And yet, art, entertainment, and sport are something entirely separate from the usual strata. If she still wanted college, then she can do it at any age. The college experience of going at 18 and experiencing that sort of social scene is overrated and, frankly, often destructive, full of terrible choices and drunken mistakes. Older students often get more of what matters out of their college years.
Evgenia is already at the top (she is the best at what she does, is famous, is wealthy) -- a thousand degrees won't make her of a higher status than she already is. Pretty much the only thing that could would be marriage to an aristocrat or oligarch. Because she has already achieved the highest things possible in terms of "status by merit." The only thing she lacks, from a sociological point of view, is the sort of status that comes from inherited wealth and power.
University gets you upper middle class professional status -- something much below a famous athlete. There are a million doctors for every multi-Olympic medalist, after all.
Note -- I am not saying that she should marry for status -- not at all, just that college won't do anything to change her status. From the point of sociology, it isn't even needed for a woman (as she would take the status of her husband, if she married). If she had some professional goal that requires a degree, fine, great, but in the eyes of most, it's a postscript at best, and certainly not as high status as World and Olympic prizes.
