Yes I feel I have a much better chance this year, if nothing else I have more life experience. I'm pretty young, 22 so it doesn't impact me too much, although I don't think you should consider 28 to be an older student :) It sounds like the experience you're getting is just what they're looking for, as long as you get enough, plus it seems like you have a lot on your plate which looks good.
Your two years of French will be fine...don't worry! Mine was a weird situation, it's not for the School of Nursings requirements, it's for UW. I took my language in High School as well which would have been fine, but it was in Alaska where there was a weird language cirriculum. So basically I just had to take two more terms of a college level language to make up for AK's misgivings. :)
So do you have a good supervisor picked out to write you reccomendation? It's so comprehensive that it's hard to choose....
If you are a post-bacc did you apply to their Accelerated Bachelors program?
