Benefits, Awards & Scholarships:

Gold/silver/bronze/merit awards will be presented to the students based on the total marks scored in the first round and second round of the competition.  Up to a maximum of 20% of total registered participants will be awarded Gold, Silver or Bronze in the ratio of approximately 1:1:2 based on merit. Medal will only be awarded to those who meet the minimum/passing scores for R1 and R2. The next ~15 to 20% will be awarded Merit certificates.  Certificates of participation will be awarded to all other students who attended R1.  The criteria will be followed as closely as possible but is subjected to change by the main organising committee.

Awards will also be given to top performing schools based on the total number of medals won. There will be 3 bands of top performing schools. Number of awards given will depend on the results year to year. Generally, 2 schools in band 1, 3 schools in band 2 and 4 schools in band 3.  However depending on the results, the number of schools in each band will depend on the performance of each school every year. Overall top students will also be given awards based on overall individual scores and scores in each round.
