## Summary

Fields Medal winner Richard Borcherds, a UC Berkeley professor, says he no longer assigns graded homework because AI use makes it impossible to tell whether students wrote their own work. He now assesses students mainly through in-person exams with no electronic devices. Borcherds told the New York Post that average online exam scores have risen sharply.
