It seems like they're attacking the wrong end of the problem by trying to detect fake students in the classrooms. If the issue is that people are signing up for financial aid and then disappearing with the cash they'd be better off making sure that the people who get financial aid actually are who they say they are before sending them money, or better yet stop giving cash as financial aid and instead give some type of credit that can only be spent on/at the school.
Once scammers can't get access to the money the problem of bots in the classroom will mostly go away.
