If I joined 2 or more competitions, how the achievement marks are being computed?

The system will auto computed based on the average mark taken from the best 2 category among the 3 category (Club & Society, Uniformed Group, Sport & Games) and add on to the bonus marks obtained by the student.

For e.g. if the student join more than 1 activities under same category (Sport & Games) Basketball and Football Team, the system will only take into consideration the highest mark that student obtains for either 1 of the activities.
