I am hoping to undergo the same thing myself. I have a conditional acceptance to the program at Marine, they are still waiting for my high school transcript, which they should have received 4 weeks ago (don't get me started.. a bit of a screw up @ CFRC had them open the transcripts they were supposed to forward with my application).
I am very interested in hearing how this all works myself, as we are both hoping to relocate to St. John's as it is a two year program... I also, however, have a dog. I'm thinking it's going to have to be off campus for me. St. John's has, apparently, a 1% vacancy rate about now. Everything is a basement apartment, and because of the high demand, apparently not all the places are that nice. I'm a little worried about the whole thing, but it will work out one way or another, I am sure.
