The CS department is under Grainger College of Engineering. According to the PDF, the CS applicants skew the acceptance rate for college. In the PDF, the acceptance rate is a lot higher for engineering applicants.
I don’t really know whether the information is legit or whether the 22.3% for the college of engineering includes CS applicants. That’s why I emailed the regional AO.
Obviously I’m going to apply regardless, but I’d rather know what to expect. (Don’t want to get my hopes up too high only to be disappointed)
