This repo contains a little research that tests hypothesis about the shortest test options. (Take a look at is-shortest-wrong.ipynb)

Another files:

• dataset.csv - ZNO in ukrainian language and literature 2006-2020 years tasks
• webscrapper.py - script that was used to collect that data. I prefer not to say what site I used to collect data, so config.py file required to start this script is not provided. If you know the site url you can recreate it by yourself.
