C and F Blocks C and F are the newest buildings of the school, with Block F being finished in 1998 and Block C in 1999. They are the highest buildings in the school at four storeys and six classrooms to a level. The predecessors to these new buildings were two-storey ones. The topmost level of Block C holds the Computer Labs 1 to 3, with 4 and 5 being kept at the former science labs at Block A. Block G This is the oldest building in the school, and its ageing condition is evident. This block's classrooms were used until 2004, where the last occupants were two Lower Six classes. Its classrooms have been converted into bookshop, gymnasium, counselling section, school cooperative, prefects' room, prayer room, dental clinic and bookloans room. A pathway which splits Block G into two leads down to the air-conditioned music room, Amateur Wireless Society room and numerous sports stores. Sixth Form Block The Sixth Form Block houses most of the sixth form students and eight of the school's 14 labs. The Sixth Form Block holds a library for the students and has seven lecture halls which have been partitioned to form nine classrooms.
