Program Overview

The Preparatory Class for Nature and Life Sciences in Algerian Higher Schools of Preparatory Classes (CPGE) is a two-year intensive academic program designed to equip students with a strong foundation in biological, chemical, physical, and mathematical sciences. The program serves as a gateway to elite national schools such as veterinary institutes, agronomy, biological sciences, and environmental engineering schools.

The curriculum is multidisciplinary, focusing on subjects essential for understanding life and natural systems, including general biology, cell biology, ecology, biochemistry, genetics, and physiology. Students also study physics, chemistry, mathematics, and earth sciences to develop analytical and problem-solving skills necessary for scientific research and applied sciences.

In addition to scientific courses, the program emphasizes language proficiency, particularly in French and English, and develops communication skills, critical thinking, and scientific reasoning. Practical laboratory sessions, fieldwork, and projects are integral parts of the training, fostering hands-on experience and research methodology.

By the end of the preparatory cycle, students are prepared to take national competitive exams for admission into specialized higher schools. The program aims to produce highly competent students capable of succeeding in advanced studies and contributing to the development of the biological, agricultural, and environmental sectors in Algeria.
