I'm trying to get into grad school in london
Places are quite tight and it's more difficult to get in these days, I'd get in touch and chase direct rather than waiting about for them to get back to you.
Most college students will have had conditional offers, if you havent had one of these by this time of year (I dont want to put you on a downer) it's unlikely you're going to get a place this year.
Good luck :0)
