German universities tighten exam policies after AI cheating uncovered

A professor at a German elite university discovered that many students had used artificial‑intelligence tools such as ChatGPT to answer exam questions. The analysis showed average scores of 96 out of 100, with 40 students achieving perfect marks, and many answers matching AI‑generated text verbatim. In response, the professor reinstated mandatory in‑person final exams, after which average scores fell to 48.

The incident has sparked a broader debate among academics about the impact of AI on learning. Professors in Germany and the United States warn that reliance on AI could erode students' critical‑thinking and writing skills. Universities are reviewing curricula, adopting detection software, requiring disclosure of AI use, and redesigning assessment formats to preserve the educational process.
