I have had a similar experience. I've been *unofficially* told that it will be good news, but had the same issues that you had with getting the letter... (you'll hear by this day, then by this day, then by Friday.. etc.) last I heard was Monday or Tuesday. Very frustrated with the wait and the continuous push backs.
glad to know it's not just me. I thought everyone else had received their decisions.
Advanced Standing people: I called again today and they said their goal was to start getting them out today, but that didn't happen and we should expect to hear by Friday this week. (She said it could be sooner-but at the most it would be by Friday) they are reviewing the BSW courses so they can send out any additional classes we'd need with the admissions letter.
Stay calm friends!
New to this post, but I applied to the Advanced Standing program and am still waiting. Columbia is my top choice, so I am checking my email and the application status constantly...It is tearing my nerves up!
