I used to live in Banff Trail and would ride home from downtown. To lessen the grade, you can take 10th st, then cross at the SAIT road. This is OK, but you have to get across 10th, and deal with more traffic than I like. The lowest gradient option with the least amount of dealing with traffic is this one right here:

This climb is very gentle and you shouldn't have a problem with it. Once you cross 16th(underneath) you can either stay on that road and at Nick's get your way on a path to 24th ave intersection, or do as I've shown and take the bridge. Depends where on Campus you are heading.
