Cuban National Chemistry Contest 2026

Description

This contribution compiles the problems, solutions and results of the Cuban National Chemistry Contest (CNQ) for high school students celebrated nationwide this year. This chemistry olympiad is an annual competition that encourages high school students to study the chemical sciences during their bachelor's degree. It is sponsored by the Cuban Ministry of Education, the Cuban Society of Chemistry, the University of Havana and other institutions. Tenth-, eleventh-, and twelfth-graders (15-18 years old, on average) are welcome to participate. It takes place in every province of the country at the Vocational High School for Exact Sciences (IPVCE). It is organized as a two-day competition in which students solve two sets of theoretical or theoretical-practical problems created by previous contestants and mentors. The problem sets have both common questions for two or three grades and individual questions. The highest scores are awarded with gold, silver and bronze medals. Top winners are part of the national pre-selection and are invited to Havana for a short training period. After a final selection round, the national team for the International Chemistry Olympiads is formed. The exam qualifications were conducted in Havana by a committee composed of selected students and mentors from the University of Havana. Herein, the problem sets of the Preparatory Problems booklet, the national exams and their solutions, and the results of the Cuban students in the national and international competitions of the previous year are provided in the official Spanish version and English translation.
