Why this WebApp?
To become a good problem solver, we need to practice consistently. This web app provides high-quality mathematics problems for anyone who wants to sharpen their problem-solving skills by solving mathematics problems. If you are a student preparing for a mathematics competition, this web app can also assist you with your daily practice. Personally, I love solving mathematics and coding problems as my daily "exercise" and hobby. This web application utilizes caching and chunking to reduce the page load time, ensuring that bandwidth is not a concern for you. You can also get the problems used in this web app by downloading the files from GitHub. Currently, only OSN regional (OSK) and AIME problems are available, and more problems will be added over time.
