As an average student, u better focus on your studies &
improve your grades cos in order to get into the top 5 jcs, u need
to get single-digit aggregate.
The principal will not look at your CCA cos they have too many good
applicants vying for these places.
The only exception is when u are presenting S'pore in sports like
swimming, table tennis etc. My daughter's fren, a National player
was offered a place in RJC, ACJC- he was told he only need 20
pts.
One of her frens tried to appeal as she got gold for choir but was
rejected cos they say they don't need so many singers.
