Artem looked down at the "Online" version of the test shimmering on his tablet. The first problem featured a truncated pyramid—a frustum—sitting lonely in the center of the screen. He had to calculate its lateral surface area. He closed his eyes, trying to visualize the shape. In his mind, the lines didn't just stay on the paper; they rose up like the glass skyscrapers of the Moscow International Business Center he saw from his bedroom window.

The screen flickered, processing his data. For a second, the circle spun—a perfect geometric loop. Then, the score appeared: 100%.

Artem exhaled, the tension leaving his shoulders. He looked out the window. The world outside wasn't just a collection of buildings anymore; it was a masterpiece of sines, cosines, and perfectly calculated volumes. He hadn't just passed a test; he had finally learned how to see.

To his classmates, it was just a packet of diagrams and formulas. To Artem, it was a map of a world he couldn’t quite inhabit.

Question 14 appeared: a sphere inscribed in a cylinder. It was a classic Archimedean problem. Artem smiled. He remembered his grandfather telling him that geometry was the "music of the spheres." He calculated the volumes, his fingers dancing across the touchscreen. The digital ink felt permanent, each "Submit" button a heartbeat of anxiety and hope.

As the timer ticked down to the final sixty seconds, Artem reached the last problem—a complex vector analysis in three-dimensional space. The coordinates seemed to float off the screen. He took a deep breath, adjusted the "zoom" on the digital diagram, and found the intersection point. Click. "Time is up. Devices down," Petrova commanded.

He began to type. He wasn't just solving for S ; he was building. He navigated the online interface, clicking through the multi-choice options with a rhythm. The KIM wasn't just a test; it was a digital gatekeeper. If he passed this, the architecture academy was within reach. If he failed, the angles of his future would collapse into a flat, two-dimensional line.

"Ten minutes," Madame Petrova announced, her voice as sharp as a compass needle.
