Really? My friend wants to change his son to 軒小(morning class) as she also knows the chance to get into QC is high there. So, do you mean even non-band1 can do so by 派位?
As I know, the 'academic gap' between students is very very large in QC. Take the CE exam as an example. They have 10As as well as 10Es. Arts students with only 14 points can have the ticket to F.6, which is almost impossible in other band 1 schools. So if your kid is not considered by the teachers as the elites, it may create a headache to you.
Yet students in QC are nice and gentlemen-like, in my opinion. They are hard-working and independent. The brotherly love and team spirit are really strong. My grandpa, uncles, father and cousins are QC graduates/current students and all of them love the school very much.
