"6학년" refers to the sixth grade in the South Korean education system. It is typically the final year of elementary school, where students are usually around 11 to 12 years old. In this grade, students build on their knowledge from previous years and prepare for the transition to middle school. In 6학년, subjects such as Korean, mathematics, science, and social studies are taught. Students also engage in various activities, including arts and physical education. This year is crucial for developing academic skills and social interactions before moving on to the next stage of their education.
