Hey mate, yes, the course will be abit challenging, however, it is up to you through how much you pay attention and study.
You can find out your subjects on the uts website, just do alittle searching.
You also find them out once you have enrolled.
But ill wont brake your balls this time

You have one physics class each semester (cant remember what they're called), chem is the same and ditto maths. You also have one elective, either biosphere(im doing this one

) or gentetics.
Just serach the uts site man, most of your questions will be answered there.
And when the hell yopu enrolling? If you havnt yet i feel sorry for your timetable lol.
TC!
