Frequently asked questions

On what problems is doubt support service available?

Currently, the doubt support service is limited to problems in the difficulty range 0 - 1600.

What is the working time for the service?

The service will be available from 10 a.m. to 2 a.m. IST on all days of the week.

Is there any fee for the service?

Currently, the doubt support feature in the 0 - 1600 difficulty range is free for all users. However, we firmly believe that to sustainably run this feature - we need to find the balance where users pay CodeChef for doubt support and doubt solvers to get paid by CodeChef for their effort. We will make this transition by the end of June.
