It is this bad, according to the Washington Post:

Roberto Serrano was shocked when he saw the results of the midterm exam in his advanced mathematical economics class at Brown University last semester: The average score was 96, when in the past, it had ranged from the 60s to the 80s. Nearly half of the students this year got a perfect score of 100.

When he and his teaching assistants ran the exam through a large language model, ChatGPT, it gave an odd, convoluted process for solving one problem rather than a straightforward direct proof. So did numerous students.

He had decided, after the deadly classroom shooting at the school in December, to allow take-home exams for the first time. And he had just learned that those can no longer be trusted to measure student learning, even at an Ivy League school…

After he switched the final exam to an in-person, three-hour test, 27 students dropped the class, he said. Twenty-two of them had gotten a perfect score on the midterm.

The average score on the final was a 48.6.

Business Insider charted the midterm versus the final exam scores among the students who actually took the final:

Student 1 is a star (does he or she want a job?) and student 22 deserves credit for putting in hard work. But most of these cheaters were caught red-handed, and so far Brown has taken no disciplinary action. We have no reason to think cheating is any less rampant at other schools.

We’ve failed to teach our children integrity. There’s one thing worse than failing: that’s cheating.
