可以讀大學的中西史嗎?

may be I can answer your questions

1) about 40%, that means all students have 40%, surely F.7 graudate will have more proportion, so if you want to promote to university, you need to work hard la~

2) I can say that your case is so special, if you want to promote to university, mostly you will study in relevant subjects such as engineering, science; ofcourse you can apply in some Arts subject such as history, chinese literature, philosophy and so on, but your application are so difficult to success and you will not have credit exemption although you can study in, so you need to think about it la~

3) I think that you study in higher diploma is better (that my own ideas, for your reference only) because if you finish to study in F.7, if you fail and cannot promote to university, it not provides any advantages to find out a job, on the other hand, after you finish to study a higher diploma, if you not want to study in university and find out a job, hold a higher diploma is better because you have professional knowledge in one field, also you can think of promote to university after finish to study this diploma, so it is a better way that I think~

anyway, I think that study in dip is more safety and you can also have chance to promote to university, hope that I can answer you questions la~

i want to know too for question 3
