To be eligible to participate in the next round, participants must qualify the previous round. There is NO pre-decided cutoff. We will set a cutoff after we analyze the performance of all the participants.

More FAQs

Who will be given preference in ranking if two participants score equal points?

If cumulative scores are equal, preference will be given to the participant with the higher score in the final round. If the final round scores are the same, preference will be given to the participant with higher second round score. If that is also same, preference will be given to the participant with a lower level of education. If the education level is the same, the younger participant will be given preference.

Why do we charge a participation fee?

The participation fee is necessary for funding of the competition- advertisement costs and cash prizes.

Why are we charging separate fees for the three paid rounds?

To make the competition more affordable, we will not charge the full fee in one installment. We have divided the fee among the three rounds. This so that if someone has qualified for the first round and wants to participate in the second round to obtain a certificate, he/she will have to pay only 299 INR /5 USD instead of the 474 INR/ 7 USD total fee. They can exit the competition after the second round with the certificate. Certificates will be awarded only after all three rounds are complete.

Prizes and Certificates

Participants of round 2 and above will receive certificates. You will be awarded ONLY ONE certificate for the competition, and not one for each round.

Top few participants of the Round 3 will be awarded cash prizes. For IMC21, we will award 10,000 INR worth of cash prizes to 5 participants. The amount will be distributed as follows:

14,000 INR
22,000 INR
31,750 INR
41,250 INR
51,000 INR


  1. There are no awards/certificates for Round 1 participants.
  2. Qualifying for Round 2 is not enough to be awarded certificate. You must register and attempt Round 2 to receive certificates
