university advice

hello, my name is siham. im in the 10th grade. I was wondering how to get accepted into my desired college, and what are the things i need to do or extra courses i should take to build a strong college resume. I kind of feel lost because im a Canadian currently residing in Egypt and we dont really have many extra curricular activities or extra courses, but im planning on going back to Canada in the 12th grade and university, so all i need to know if theres anything i could do while im here so i can get a head start.

P.S we dont have SATS and dont use the credit grade system here.

Thanks for the opportunity to ask you guys, and please help me because i need all the help i can get
