Hello everyone, I am Keshav Dhandhania. I represented India @ IOI in 2009 and 2010.

I and some IOI alumni and coaches have started an International Olympiad in Informatics community. Some cool things about the community

• Tutorials on beginner concepts focus on simplicity, intuition and fun.

• Solutions are given hint by hint. Using hints helps you improve faster than reading the full solution to a problem. Moreover, creating good problems is tough, and CodeForces and TopCoder problems are not the same as IOI-style problems. (sample 1, sample 2)

• Flexibility for each country to focus on problems from their individual training camps (samples). We would love for you to upload the problems used for practice in your own country.

Hope you guys like it! Join the community to get updates — it is hosted on a platform called Commonlounge.

Feedback and suggestions are welcome :)
