Ateneo de Naga University is the Regional Testing Center for Region V of the 21st Philippine Mathematical Olympiad.
The Philippine Mathematical Olympiad, a nationwide mathematics competition open to all junior and senior high school students of the Philippines, is carried out in three stages.
The qualifying stage (to be held on October 20, 2018, Saturday) consists of a written exam administered in fourteen regional testing sites. The exam consists of fifteen multiple-choice questions worth 2 points each, ten multiple-choice questions worth 3 points each, and five answers-only questions worth 6 points each.
The area stage (to be held on November 24, 2018, Saturday) consists of a written exam administered in testing sites for the four areas (Luzon, Visayas, Mindanao, and National Capital Region). The exam consists of twenty answers-only questions and three open-ended questions that require full solutions.
The national stage (to be held on January 26, 2019, Saturday) consists of a written exam and an oral exam administered in Metro Manila. The written exam consists of four open-ended questions that require full solutions to be answered in 4.5 hours. The oral exam (which is open to the public) consists of 30 questions read to the participants and to be answered within a specified time for each item.
Each school may send up to thirty participants (students with a final grade of 88% (or its equivalent) in mathematics in the previous school year). The participants with the top fifty scores in the qualifying stage per area will qualify for the area stage. The participants with the top twenty scores (national ranking) in the area stage will qualify for the national stage. The national finalists will be qualified to join the Mathematical Olympiad Summer Camp (MOSC). The representatives of the country to the International Mathematical Olympiad will be selected from the participants of the MOSC.
