I don't normally post on these boards (just often look) but I thought this would help... some info that I got from ICO today:
They are NOT done handing out acceptances - in the admission counselor's words, they are "still interviewing applicants and reviewing files." She was also able to tell me that the class is roughly 2/3 full. From last years stats, I would guess that means that of however many acceptances they have already handed out, about 100 people have sent in their deposit for enrollment.
If you want to go to ICO and are still waiting to hear, keep your hopes up... I turned in my app in late September and my interview is scheduled for next week. Crazy! There were some discrepancies with my transcripts, so make sure you follow up very specifically and make sure that ICO has everything they need to consider your app "complete."
Hope this helps anyone!
