What defines nontraditional anyway? Those who didn't get into a school two years out of high school? Because I'd wager that most of the P1s yearly are older than 20. I'm 26, and sure, if things had been different, I would already be practicing by now, but life happened the way it was supposed to happen.
Then you have the issue of those who are married and/or have kids, but a considerable size of my class specifically falls into this category. About half of those who matriculated also had 4-year degrees.
So I'm not really understand what "nontraditional" means. We all have to go through a similar application process.
