Important Operations Procedure

The organizer will no longer provide invigilators to schools.

Schools that intend to conduct the competitions within their premises have to arrange for their own teachers to invigilate the competitions (without monetary compensation from the organizer). Nevertheless, the organizer will continue to deliver/collect the question/answer scripts to/from schools. Details on such arrangements will be provided nearer the competition dates.

Schools conducting the competitions within their premises are still required to adhere to the same schedule of each competition category. This is to maintain fairness to all participants.


The organizer reserves the right to amend the rules and regulations of the competition.
