Founded on September 1st, 1967 as "Liceul de Cultură Generală nr. 43", the school evolved into "Liceul de Matematică-Fizică Nr. 3" by 1977— one of just five elite science-focused high schools in Bucharest at the time.

It maintained a strong academic profile throughout the decades, standing out among top schools such as N. Bălcescu, Mihai Viteazul, Gheorghe Lazăr, and others that later became National Colleges.

Over 80% of students are enrolled in STEM-oriented classes, including intensive English and Computer Science tracks.

The school also supports humanities students, offering a balanced curriculum that nurtures diverse academic interests.

The school offers 30 classes (grades 9–12), spanning both real (STEM) and humanities (social sciences) profiles. Specializations include:

• Mathematics-Informatics (standard and intensive)
• Natural Sciences
• Social Sciences (standard and intensive English)

With an average admission grade of 9.12, students regularly pursue degrees at top universities like ASE, SNSPA, Politehnica, and Carol Davila. More recently, there's growing interest in communication, political science, journalism, and philology.

The school encourages a serious yet relaxed academic environment, with respect and personal growth as core values. It supports all students, not just top performers.

The student body primarily comes from intellectual families, which contributes to the school’s aspirational and respectful culture.
