A tech-savvy New York teen allegedly hacked into his high school’s computer system to improve his test grades.

The New York Post reports 16-year-old Eric Walstrom made it past New Dorp High School’s highly secure computer security system using a computer in the school and setup his own network in order to access it from his phone.

The student was caught when an IT worker noticed someone was logging into the system without authorization, the newspaper reports. The Staten Island school notified police and Walstrom was arrested Wednesday.

Walstrom was charged as an adult with forgery, computer trespass, unauthorized use of a computer, computer tampering and criminal possession of forgery devices.

The student studied advanced computer programming at an elite computer camp held at several universities, the Post reports. The camp teaches computer infrastructure programming and various computer languages.

One student, Sean Morris, told the Post that Walstrom is “super quiet” and uninterested in school.

“Maybe he can get a Secret Service job later on,” he said.
