In my school,every subject is taught... I take math,eng,bus,ICT,phy,chem,and bio as my high school subs... so the high school certificate I will get,will be for which of the following:
HSA High School Certificate (Art)
HSS High School Certificate (Science)
HSC High School Certificate (Commercial)
HSI High School Certificate (Industrial)

I would think more about HSS, since you are taking 3 science subjects + Math, while you are taking only business on the commercial side.

But on the other hand, are you taking only subsidiaries? Anything about mains? :confused:

Would have to ask where you are at, and may want to ask the school, Here there is only one certficate not different ones, although you may be in various programs

Most likely will be certificate of art and science since list all of the above.
