3.是否ue fail 就不能入讀副學士?It depends on which institution you are going to enter. Search their website plz...
5.jupas上列出的副學士學位及high dip 學位同院校其他沒有列在jupas上 的副學士有什麼分別
......自己search下la(Tips:同錢有關)
6.選科時選工商管理(GENERAL)比較好還是選好專科比較好如工商管理(MARKETING)
From my own experience, almost all BBA are not good.
I suggest you to select on your own interest.
