RJC offers students a wide range of choices for their co-curricula activities (CCAs). These CCAs give students the opportunity to explore and develop their interests and showcase their talents in well defined non-academic areas, as well as allow students to develop their character and leadership skills while having fun.

RJC empowers students to initiate CCAs, which are then carried out with the guidance and advice of teacher-advisors. RJC also partners community and grassroots organisations to provide enriched CCA opportunities for students.

The following are CCAs currently offered at RJC:
