I assume you'll have to trek into Denver to go to school, correct? I'd look at commute times depending on what time in the morning or evening you'll be heading into Denver. I'd recommend somewhere along US 36 in the northern part of the Metro area so you could miss the traffic on I25 at all times north of Denver. Going into Denver in the mornings on 36 really isn't too bad as everybody is travelling north and you'd be going south. The opposite is true if you'd be travelling the most in the evenings. Broomfield, Westminster are pretty good depending on the place you choose.
