how to become a good architect?

I'm 16 years old, turning 17 in a month.
I've been thinking about choosing my future profession for a while now and I'm stuck to the idea of being an architect.
I love the idea of designing new buildings, also studying the history of architecture and I love to draw.
however, there aren't many good architecture schools where I live and I really want to become an exchange student. but my grades aren't too good, I usually get 8,9 or 10 out of 10 so is that considered good enough?
I'm willing to work hard to become an Architect so what are some good Universities for Architecture allover the world? how should I prepare to being an Architect? and how to be successful?
