In Russia there is a national exam for 9th-grade students called OGE (Основной государственный экзамен). One of the subjects is Informatics, which includes a programming task. It so happens I was going to take this exam despite knowing more than any of my teachers.

The problem

The official exam provider offers a basic training suite that shuffles pre-made tasks. It also does not support harder tasks and has no code testing.

The solution

My generator is real. It creates a problem randomly and generates a solution based on its conditions. It can compile and test JavaScript and Python for the last exam problem. It allows user to test their word processors knowledge by embedding a rich text editor into the page and checking the submitted formatted text. It also embeds a table editor for spreadsheet operations exam problem. It checks the solution instantly and automatically and works offline.

I used React, Reactstrap based on Bootstrap, EditorJS, html2canvas, jszip, xlsx and codemirror. The website is absolutely free, 100% open-source, has no ads and works entirely inside of the browser.
