高考修AS數學及統計學可以補讀大學甚麼課程?

You can choose to major is statistics. Or you can study BBA. In fact, some universities (as I know - HKUST) will not require you to study HKAL or HKCEE Eocnomics or Accounting when you enrol in the courses. So if you are interested in BBA, you can study. Apart from these, Architecture study in HKU.

Hope it helps.
