Lol, same problem as me, but different subjects.
If u cant change to any other tutes/ lectures, if u call UPO, they will tell u some useless shit like "drop a subject"
but first, im gonna wait til uni starts and IF they allow u, just enrol into the tute / prac / watever.
But in ur case, if u want to attend both lec / tute, i think that lectures are total shit at UTS and they prolly wont help u at all, so just attend the tute = )
