This is how UIC does its application: they use a point structure. When the applications come in, they check for completeness. If completed, it will move to the next step. It will be reviewed, and points will be assigned. You'll get a certain number of points for GPA and PCAT. Somehow, the assign points also for ECs, LORs, etc. The top 300 will be invited for interviews on the week of UIC spring break, which is the week of March 26.
After the interview, the interview and essay points will be added in. Then, a final decision will be reached: accepted, wait listed, or denied.
On a side, the University of Illinois system does not consider legacies.
