I visited a test center in Ankara during a national exam. The security was airport-grade: metal detectors, signal jammers, even thermal cameras to detect body heat anomalies from hidden electronics.

Inside the foil: 10 mg of a generic ADHD stimulant, a beta-blocker to stop the heart from hammering out of his chest, and a tiny, almost invisible earpiece—smaller than a lentil.

They doped their hafiza for the exam. They erased it for life. The authorities are fighting back, but they are losing.

The Memory Center.

She took a long drag of her cigarette.

This is where Hafiza gets literal. Using miniature Bluetooth receivers (often smuggled in as hearing aid batteries), a student sits for a university entrance exam or a medical school final. Outside, a “proxy” (often a former top student or a hired gun) whispers the answers.

In Turkey, a country with one of the most brutal university entrance systems in the world (the YKS), nearly 2.5 million students fight for just 800,000 spots. A difference of 0.5 points can mean the difference between becoming a doctor or a security guard.

They call it Hafiza Merkezi .

The boy in the hoodie didn’t look like a criminal. He looked like he hadn’t slept in a month. Across the chipped wooden table in a back-alley tea garden, he slid a blister pack across the surface. No names were exchanged. No money changed hands visibly. Just a nod.

“We don’t do this because we are lazy,” says Dr. Aylin Keskin, a clinical psychologist who has treated over a dozen students for stimulant-induced psychosis. “They do it because the system has told them that memory is the only currency that matters. If you have no memory, you have no future. So they buy memory.”

Propranolol. A blood pressure medication. It stops the physical symptoms of anxiety—the sweat, the tremor, the thumping pulse that gives cheaters away. “You could have a gun to your head,” Emre told me, “and your pulse would be 60.” The Economics of Desperation Why risk expulsion? Why risk the permanent arrhythmia caused by street amphetamines?

“But last week, I forgot the sound of my sister’s laugh. I know she laughed. I know I loved it. But the sound… it’s gone. I deleted it to make room for tort law.”

She now has a tremor in her left hand. She cannot sleep without sedatives. She is a rising star at a law firm.

He is a third-year engineering student at a major university. For the purposes of this article, we will call him “Emre.” He is part of a silent, terrified, and rapidly growing demographic: young people in high-pressure academic systems who are no longer just studying for exams. They are engineering their own cognition .

“Last year,” a proctor told me, “we caught a student with a pencil that had a hidden camera. He was filming the test, sending it to an AI solver outside, and receiving answers on a smartwatch disguised as a button.”
