Peter knew it was wrong. The answers were not just numbers—they were elegant, suspiciously perfect. Problem 1 (a): a = g sin θ – μk g cos θ . Problem 1 (b): T = 2π √(L/g) for the pendulum follow-up. Every step was laid out like a confession.

Peter made a decision. He took out a fresh notebook. He would not copy the answers. Instead, he would reverse-engineer them. For each final answer, he derived the physics from scratch, checking if the path matched the destination. When he tried Problem 3—an electricity question with a capacitor and a dielectric—his own work initially gave a different expression. He redid it three times, then saw his mistake: he had forgotten the battery was disconnected. The leaked answer was correct.

The answers had been wrong for the test—but right for his life.

At 8 AM, he sat in the high school gymnasium among two hundred sweating students. The proctor handed out the booklets. Peter’s heart pounded when he turned to the free response section.
