呂郭碧鳳 開到全英文班 because she had so many applicants at the first round (few years ago), which are Band 1 students and she had applied to Education Bureau for opening English classes. (The above is reported by a newspaper).
Last year, many Band 1 girls use 德愛 as 5th to 10th choices as safety net. 德愛 has very few seats for Kwun Tong. I think 德愛 has been taken by Band 1 girls. If your 千金係B2生, do you think that you still can get 德愛?
