Hi everyone, hope you’re having a good day
I bring to you USACO Rating ! USACO Rating is a web application tool for estimating USACO problems’ difficulties in terms of CF ratings. There is also a quality metrics, so you can practice on only the most worthy problems, and avoid low-quality ones. The website is here: https://codetiger.me/project/usaco/
We are also currently looking for more volunteers to better adjust the estimations through voting. If you’re interested, please check out https://codetiger.me/project/usaco/frontend/contribute.html
As someone who has always struggled to find USACO problems with the correct difficulties, I know the pain of attempting a question and only realizing after reading the editorial that it’s either too easy or too hard, wasting a precious problem. Therefore I hope this website can serve as a remedy for that issue . Hope you find it useful! And please contact me if you have any feedback!
