The students of the gifted class are taking the courses designed to improve the ability for the scientific exploration experiments and math problem resolution during weekends. In addition, they visit science institutes or universities to stimulate the curiosity, and improve their ability through team-based research competitions. The students of the gifted class are selected by the recommendation of their homeroom teachers and the results of the creativity test. The teachers observe the students who they consider to be talented in science and math during the first grade.
