Okay here is some advice on the schools from someone who didn't graduate 20 years ago like many posters here, but from someone who graduated a few years back,
There is no superiority in Calgary of the schools you attend, it's all about what your marks are, the public system is great here, and there is no need in going into private schools here in all honesty, it will not make a difference into your application into various universities. That being said, environment in many of them is different, I went from a school like Beaverbrook, to Centennial High School and I appreciated school there more, in terms of teachers, the environment, and especially the people. As the poster above me wrote exam's rank order of the school should not really be a deciding factor either, as it is determined by the students and their willingness and desire to learn
Oh and the housing situation, try taking a look into new developments in the SE, yeah it's a little further commute to the inner-city, but a lot more awesome things down here
, and the new hospital just went up, that's coming from a guy living in the far SE Calgary since I immigrated here in '97 (mckenzie lake, mckenzie towne, douglasdale/glen, auburn bay, copperfield... etc google maps) I despise the north lol, whole different world up there
