Buddhist Students' Association
This society's main goal is being an ain to all children as well as adults who strive hard to live their daily life. We as the society represent our school in various events organised by the school as well as outsiders. Two of our main school held events are the blood donation campaign and the sil program. These two are our main annual events but we were unable to organise the two projects for 2020 and 2021 because of the corona pandemic. Our society includes of only Buddhist children in school.Latest Project
Lending stationery items to children of the schools minor staff
This project was held in 2020. All the members took part in this project by lending money to our president to buy the required items as they couldn't by themselves because of the pandemic. As planned the president bought all the required items and handed it over to the children of the minor staff.
