What is Hong Kong University (HKU) 's acceptance rate for international students?

I'm also wondering if i could get in. My GPA overall would be around 3.0-3.5 while my SAT score is around 2000, my dad was a student at HKU and CUHK (he is actually still in CUHK program now). How likely am I going to get in for HKU med? I also took the AP bio test and didn't get results yet but it's a 4 or a 5 while i scored 660 on SATII bio and planning to take SATII chinese and chemistry along with the AP chem test and AP Calc test during senior year(coming up year). What are my chances of getting into HKU or CUHK?
