High School

The four-year curriculum prepared by GGS offers a diverse range of learning opportunities tailored to students' abilities and interests. The high school curriculum is based on the Common Core State Standard (CCSS), which consists of basic subjects such as English, Mathematics, Social Studies, and Science, and students learn to the level required for college entrance exams.

Students not only learn English as a language, but also as literature, which helps set the guidelines needed to later express their thoughts and experiences at the necessary writing level required for college entrance preparation. Mathematics courses are organized to improve logic and reasoning skills and are designed to cultivate students' problem-solving skills by learning calculus, to later be easily linked to the learning processes after graduation. Basic social and scientific subjects are provided for four years, as well as other AP subjects can be provided to improve student diversity and expertise.

In addition, in order to strengthen sociality and professionalism, extracurricular activities are encouraged by reflecting and encouraging individual interests as much as possible. Various club activities are held to satisfy students' future-oriented needs. Students are encouraged to invest a lot of time to maintain and develop their interests in order to strive to become community members with leadership and cooperation necessary for society. Volunteer activities in and outside GGS are also actively encouraged to foster responsibility and a spirit of service as members of society.
