It is within 30 days of "the date of this letter". I was in the first round and the date on mine was February 6, 2008. So my deposit would be due on March 7,2008. I imagine that this is the earliest of due dates so don't stress out yet, just keep that in mind. If you get to the point where you think the letter got lost in the mail or something, you should probably give them a call to check in with them. . . Especially if your name shows up in the search!
On another note, I had a question of my own. I did the academic update thing through pharmcas a few weeks before my acceptance letter came in the mail. In the update I added my "classes in progress" for spring 08. Of the 3 classes I am in this semester, none are pre reqs for Creighton. 2 were pre reqs for other schools I was applying to, and 1 was just an easy gpa booster. Now that I am accepted (and Creighton was my 1st choice) I want to drop one of the classes. How should I go about this? Do I need to let them know? I know they accept students assuming everything they have been told so far. Ex: If you say you will be completing a BA degree in June, they accept you, then you don't finish the BA, then they can dismiss you. Would my 1 class fall into that category? I hope not, I'd really like to just kinda take it easy this semester. I'm already working 40 hrs per week. The 3 classes on top of that makes life a little exhausting.
