of course! assume if ALL K3 students applied SPCC, DGS and DBS! (which i think its impossible!) therefore the admission rate for SC students getting into these schools are AT LEAST:
SPCC rate 29/600 = 5%, DGS, 30/300 girls = 10%, DBS, 30/300 = 10%. i think its quite good figure, you cant compare the percentage rate with CCKG.
Total 89 offers (but may have double count as some students may be offers from 2 out of these three schools) from these three schools have gaven offers to St Cat students (total 700 +), so the successful is around 12.7%. Then my guess is around 10% would not be too far off. This ratio should be high vs. other schools (except CCKG or BH).
