Register yourself here for basic track and here for advance track. Do it only after you have found out if there is an existing team from your college or not. You can check that while filling the registration form on entering the college name. Details of the team leader will appear on the form for already registered teams.
Anyone who is interested can apply and become the part of or form their college team. But there are certain documents that you need to send to us for completing the registration process. These requirements are different for all the tracks. You can go through the guidelines of each track to know the different requirements
You can register for NEC(for basic track) individually but you must participate in a team of 3 members.You have to add the other team members in a span of 1 month after registering. You can publicize NEC amongst the students of your college, and attract more team members.
