Well, I may present a biased opinion.. but I am a first year student and Grant MacEwan. I was just like you, coming straight out of high school. I have only heard good things about Grant MacEwan.
I know people who did the transfer program before MacEwan could offer the degree, and they urged me to go to Grant and skip the U of A at ALL costs.
I know someone who took her first year at the U of A and hated it, switched to Grant and is now in her 3rd year, and loving it.
.. now this is just a rumor I heard.. but I've heard that the U of A nursing students sometime get to come to Grant Mac to use our new, multimillion dollar simulation labs!
When I was in gr 12 trying to decide where I wanted to go.. I could only envision myself at the U. It has such a great history and an amazing community, so going there, I think, would be an awesome experience. However, if you're looking for a better program, from what I've heard, and my first semester experience, I would suggest Grant Mac.
