So you have to create a CodeChef username, if you do not have one, here. However if you already have one, you must use the same. Once you have a CodeChef username, please update the same here.
After your registration, we will be creating team login id’s for you and sending you the same, which you can use for the online contest. The mock contest is a regular CookOff contest and is an individual contest.
