tCambodia is an overseas community service project partnering the Journey of Grace Academy (JOGA) in Siem Reap. JOGA was founded by Tembusu alumni, Winson Lim, who was a Graduate Fellow in the Academic Year 2013/14. JOGA runs on the belief that proficiency in the English language can go a long way in securing jobs for the children, particularly in a tourism-driven city like Siem Reap.

The Tembusu (Fagraea fragrans) is a large evergreen tree in the family Gentianaceae. It is native to Southeast Asia. Its trunk is dark brown, with deeply fissured bark, looking somewhat like a bittergourd. It grows in an irregular shape from 10 to 25m high. Its leaves are light green and oval in shape. Its yellowish flowers have a distinct fragrance and the fruits of the tree are bitter tasting red berries, which are eaten by birds and fruit bats.
