any parents sent their kids to creative secondary school

Do any parents here send their kids to creative secondary school (CSS) ? As I want my kid to do the IB and I heard that creative primary school is a great school. Also if my kid can get into CSS, she can do IB. However, since I've done a bit of research, therefore I knew that CSS only allow 50% (I guess, right?) of students to do IB, others would have to do the HKDSE. Any parents of CSS can tell me more and share with me?
