The SGH classes at our school are for all the students. Regarding our SGH school setting subjects, there are LWI which first-year students study about Local Water Issues and GWI which second-year students study Global Water Issues. Third-year students write essays in English as climaxes for 2 years. LWI and GWI are facilitated by team teaching with their home room teachers, English teachers and the SGH adviser for international exchange. Therefore, in the last 5 years almost all of our teachers have been in charge of SGH classes.
