Seçmeli dersler are elective courses that students can choose to take in addition to their required classes. These courses allow students to explore subjects that interest them, which can enhance their learning experience and help them develop new skills. In many educational systems, seçmeli dersler provide flexibility in a student's curriculum. They can range from arts and music to advanced sciences and languages, giving students the opportunity to tailor their education according to their personal interests and career goals.
