ChatGPT-4o drafting of engineering-mathematics exam solutions

An MTU lecturer prepared AI-assisted maths solutions in 2 hours and 36 minutes

Problem

Preparing detailed engineering-mathematics solutions took substantial lecturer time.

Approach

In summer 2024, a lecturer uploaded a past exam to ChatGPT-4o and requested step-by-step solutions in LaTeX. He checked and corrected the draft before producing a PDF. He compared that work with preparing another exam's solutions without AI.
