Frequently Asked Questions
My team is made up of Pre-University Students, can I join the open category?
Yes, Teams that wish to participate in a more senior category than their own, may do so. E.g. A JC team can participate in the Open category.
My team is made up of a participant who is not Singaporean/PR, can I join the pre-university category?
No. The Pre-University category is only open to Singaporeans/PR. We will do a verification before prizes are disbursed for such categories of prizes. Teams with participants who are not Singaporean/PR are required to join the Open Category instead.
My team member is unable to make it physically for the 21 October Finals, would I be disqualified?
We strongly encourage participants under Category 2 (Pre-University) to join us for the 21 October Finals. Category 2 Teams with no participants on the actual day might be disqualified, as we are disbursing the prizes on that day.
There is no requirement for Category 1 (Open) teams to attend the 21 October Finals. That said, we strongly encourage participants who are based locally to join us physically during the 21 October finals.
What if I have more than 4 friends who want to join the competition?
We strongly encourage you and your friends to divide yourselves into teams of up to 4 members. The organising committee will require each team to comply strictly with this requirement. This is to ensure fair competition play and ease of administration for the CTF.
