Housing Assignments

Hi, so I committed to CU Boulder a while ago. I completed the housing application on April 18, but I did make some changes to it through email and phone call afterwards. The application timeline says that I was in the third application window and will hear back BY July 19. Does that mean I will hear back before the 19th or on the 19th? If the decisions come on a rolling basis, does the fact that I changed my choices after my completion date mean i will hear back later?

Maybe folks in http://talk.qa.collegeconfidential.com/university-colorado-boulder/ would have a better idea
Also you could contact the housing office and ask them

Yeah I realized my mistake and am going to post there shortly. Thank you.
