Elena tightened her grip on the stack of printouts, her knuckles white. WTW 238: Differential Equations for Engineers. The course was infamous. It had a 42% pass rate, a textbook thicker than her wrist, and a lecturer, Professor Alistair Finch, who seemed to derive personal joy from constructing exam problems that felt like abstract art rather than mathematics.

"Enjoy the problem?" he asked, his voice a dry rustle.

Then she turned the page to Question 4.

"Every paper since 2015," Elena replied. "You repeat themes every four years. 2024 was a mechanical systems year. The leaky bucket was the logical culmination."

Three hours later, Elena set down her pen. The person next to her was crying softly. The person behind her was staring blankly at a blank page.

She flipped to 2017. Harder. Laplace transforms, but manageable. Elena tightened her grip on the stack of
