In my experience of University much of student activism was done by students who struggled the most academically and often made it part of their agenda to ease academic standards.
We had student council elections, where the candidates were listed by degree and the semester, the trend was overwhelmingly that the candidates were in semesters after the usual graduation date, often having studied for more then 5 years.
Non sequitur? Where was this even remotely claimed?
What other interpretation of your words could there be except you believing that people in high political offices are above average students.
