Sam breezed through the first month of calculus and physics using ChatGPT for problem sets. Homework was fine — 90s. First midterm: 61.
The gap between homework performance and exam performance was the wake-up. Sam ran an experiment: use Brainback exclusively for the next four weeks. No ChatGPT for coursework.
Second midterm: 84. Final: 89. More importantly, Sam reported understanding the material for the first time — not just recognizing it. The Brain score climbed from 52 to 81 over the semester.
