Steps to complete online registration

Step 1 - Register here by selecting the events you want to participate in.
Step 2 - Register on the Pragyan website with the same email address that you used for your WCA account. If you are not a college student, leave the "Degree you are pursuing" field blank, mark the "Year of Study" as Other, "Name of Institution" as Other. Make sure you register in the Cube competition page too (link).
Step 3 - Pay a security deposit of ₹200 here. This will be refunded when you attend the competition and it won't be refunded if you don't attend the competition. Again, make sure you provide the same email address as in the previous two steps.
Registrations will only be approved once all 3 steps above have been completed.

Notes

1. The amount paid is a security deposit. This means that the entire amount will be refunded to you once the competition is over provided you attend the competition. No refunds will be given to the people failing to turn up for the competition in person.
2. If you fail to do online payment before registration closes, you won't be able to participate even if you had registered in WCA.
3. You can't change the events once the registration closes.

OTS will be available based on first come first serve policy. There won't be any OTS if the online registration crosses the participant limit.
