basically for first year, there;s only entrance scholarship which is automatically given to you once you reached atleast 80% based on your highschool marks. There are certain ones for outstanding students and as you said they'll need reference letters. Once u reach 2nd year, there will be some scholarship for outstanding students, not only they;ll look for your academic standing, but also your community involvement. If you are Grad student, the scholarship will be in form of RA or TA positions.
