cdnis reception

Hello, 今年幫囡囡再報cdnis reception (上年pre reception reject 咗）

啱啱收到email 話：
Xx is placing in the second round interview group. Should there be a second round interview to be offered, Admissions Office will contact you for arrangement before March of the year of admission

請問即係點？2nd round 面試嘅小朋友喺咩情況下先有得in 機會有幾高？

Thanks!
