Homestay at Aussie

Huufff, this activity is recomended in my school, but with no pressure of course. It means that if we want join or not will not be a problem. And I, Myself want to join that. I've told to my dad about the offer and tried to make him agree, but it seems like he won't agree that since he's really a protective person. Finally he agreed, but I should be the first winner in my class. You know, for the 3rd place it already hard to reach, and how about 1st? Ahhhhh I don't want to give up, but what I have to do? :'(
