How Kolly grades a UChicago essay

The grade covers the same six dimensions as every Kolly read: hook, theme, detail, authenticity, reflection, and writing, each scored from 0 to 5. The big number is a percentile that shows where your draft lands among accepted essays of the same type from top US schools. UChicago readers, like their counterparts at peer schools, read fast and form an impression in the first paragraph. The verdict quotes the line that lands and names the weakest moment, so you know what to fix first.

Why Kolly instead of a ChatGPT read

ChatGPT and other general models grade against writing in general, which is not what UChicago readers do. Kolly grades against essays that got in, and four readers argue over the draft before they vote, so a polished answer that says nothing specific gets called out instead of praised. The quick read is free without an account. A free Kolly account adds the full review: a stronger scoring model, notes on each paragraph, and a fix-it plan.
