My son is chosen for Victoria school through Sports DSA. I feel he can score 260+ in PSLE this year. This score is above the RI and other schools admission cut off.

He is interested in RI. Should we accept Victoria offer or wait for PSLE and apply again in RI.
My query is Once we wait for PSL than only schools will give admission based on academic results. What is the difference in sports DSA and Academic admission in secondary education.
Kindly suggest. Thank you for your suggestions
