CR + M is Critical Reading and Math. UChicago doesn’t look at your writing score.
I doubt it’s true that the average UW admissions GPA of 3.75. They don’t publish that stuff, but they do say that something like 98% of the class came in at the top 10% of their class.
What UChicago really does look for in admissions is your essays. Have you read the past essay prompts? If you don’t write a stellar uncommon essay, you probably won’t get in. On the other hand, there are lots of people I know who had slightly less than optimal GPAs and are convinced they got in on the back of their essays.
I recommend you do more research on what being a student at Chicago is like. Yes, our campus is nice and Chicago is wonderful. But that really isn’t what being a UChicago student is all about; if you just want Chicago and a pretty campus, I think you’d be better off going to Northwestern.
Now…you might actually be a good fit for UChicago. The truth is, I don’t know. Just realize that you will probably spend more time in the library than the loop, there are core classes you have to take where you will have to read 100 pages of some angry 18th century philosopher a week, and you will constantly be surrounded by the nerdiest people in America. Academics are king at UChicago, even compared to other schools at the top of the US News list, and coming here because you don’t think you could get into a different top university is a good way to end up depressed.
Come here if you really really really like learning, don’t come here because our business school is #5.
