Hi Jessmj,
So sorry to hear that you didn't get in this year. That must be so upsetting and discouraging ?
I would say that not having your undergrad would be your only downfall! You seem to have lots of experience and a great gpa..so I don't think you could have done much more! I have heard that they almost always consider applicants with degrees before others still working on their degree.
Try not to be discouraged and keep on trying! My friend applied two years ago and wasn't accepted and tried again this year, after completing her degree, and was accepted. A few other people I know who completed the program were also accepted with full degrees.
I would definitely contact Dal and ask for feedback so that you can have some peace of mind!
Don't give up!
