Any idea how many vacancies are reserved for non-affiliated students? I am worried about low chance of getting into the school if most vacancies are reserved for affiliated students. Tks!

My girl got 240+1. Thinking of the following:

1. Nan Chiau High
2. Chung Cheng Main
3. TKGS
4. PLMGS
5. Xin Min
6. Zhang Hua

Is this a good selection? Appreciate feedback.
