Django web application to suggest practice problems from the areas in which the user struggles to get accepted in code forces.

Improve Codeforces Performance

This project aims to improve any CodeForces User's performances in the codeforces contests by using User's previous performance in contests as well as in the practice problem-set.


This project uses Codeforces API to fetch user's Info,his/her past submissions ,etc., data and gives the weak areas (eg: math,dp,graphs,etc.) for that user.

Also it gives problem recommendation based on the weak areas and user's current rating,to improve the performance in next contest.

Getting Started

How it Works?

On the Codeforces official web page, they provide various API which we access to get data in machine-readable JSON format.That data is used for this project.

Login with the user's codeforces handle.

After submitting the handle, Details of that users and recommended problems is displayed.

Upon opening, this screen user can perform the following operation -

  • On clicking on the Future Contest, it will redirect the user to page where all future contests are listed,and also user can register for the contest.
  • User can go to the problems which are recommended and listed in the profile page to solve them.
  • User can refresh the recommended problems
  • logout
