<p>I’m not following the ratings religiously and don’t know when they are updated 
I read somewhere on cc that selectivity is only a tiny portion of the calculations. DGDzDad, I recommend you and your daughter to look closely whether UChicago has what she needs. Check out core and her potential major/s. For example, my son applied because his major (math) is known as one of the top in the country. We liked the university very much when we visited. It would fit his needs very well. However, UChicago doesn’t have an engineering school, and for this reason my son will probably matriculate to another school that has both top math and top engineering, just in case he becomes interested in something applied.</p>
