what should i put for my top three activities - application to ntu physics aba

bit of context is i got acc/c with a in GP, my c's were phys and math. although igp is ccc/d for ntu phys, i feel scared that because i got c for phys they wont let me in, so iw try my luck at aba.

i have a few exceptional activities, like i went to pre-u sem, i was selected for a stem camp to usa, but the rest of my physics related activities are not that impressive (i went qcamp at nus, i went to a quantum tech seminar at ntu, i went to STEAMunity), but they reflect my passion for the field.

however, i have more impressive stuff in other fields, i was head judge for a well known mun in sg, i had a 4-month mentorship with a ngee ann lecturer (social sci), ive performed solo dance at the esplanade, and even started a successful solo private teaching biz (dance).

which activities shd i put and prioritise, my external, internal, or hybrid? ideally pls mention specific activities that have more merit.

ideally; id love responses from seniors whove been thru the process or who have friends who've been thru the process!
