"I don't need to think," Maxim countered, his voice cracking. "I need to pass Physics and Calculus by Monday, or my mother will send me to work at the tractor factory before I can even say 'diploma.'"
The old man didn’t look up. "You mean the GDZ? The solutions? You know the teachers at Gymnasium No. 1 say those books are cursed. They say if you use them, you forget how to think."
He didn't finish every problem that day, but the ones he did were his own. As he walked out into the Minsk afternoon, the heavy bag of solution manuals felt lighter—not because they were gone, but because he knew he didn't need to carry them anymore.
"This is the 'Vse GDZ' compendium," the man said, sliding it across the wood. "It has the answers for every exercise from Brest to Vitebsk. But remember, boy—the solution manual tells you the 'what,' but it never explains the 'why.'"
On Monday morning, he sat in the exam hall. The sun hit his desk, illuminating the blank white paper. He looked at the first question—a problem involving the velocity of a train leaving Minsk-Passazhirsky.
He closed his eyes, expecting the GDZ's perfect steps to appear in his mind. But all he saw were the shapes of the numbers, not the logic behind them. He realized the bookseller was right. He had the key to the door, but he had forgotten how to walk through it.
