Electronic circuits drive a large part of our lives today. These complex works of intellectual design intimidate even the brainiest. However, if you are one among those with an aptitude to work tirelessly with circuits, then this is the place for you. Come and test your technical wizardry against the best and unravel simple but dynamic day-to-day circuits.

Prize Money INR 25,000

Date of Online Round: 7th March 2020

Time of Online Round: 5:30 PM to 9:30 PM (60 Minutes round)

On-Campus Round Date: 13th March 2020

Round 1 - Online Test:

  • This round will happen in the month of March, before Pragyan.

  • It will consist of multiple-choice questions. 

  • The test can be taken only once by a team.

  • 30 questions are to be solved in 60 minutes.

  • This round is eliminative.

Round 2 - Circuit Debugging:

  • This round will be held during Pragyan, at the National Institute of Technology, Trichy

  • Participants will be given a faulty circuit. They are expected to debug the circuit and give the correct output.

  • Round 2 is assessed based on the time taken and the closeness of the obtained output to the desired result. 

  • Virtual money for round 3 will be awarded to 8-10 selected teams.

Round 3 - Circuit Design:

  • Participants will be given a problem statement. 

  • They are required to design and build a circuit with the virtual money earned from the previous round.

  • A team must comprise of not more than 3 participants.

  • Prior registration on Pragyan’s website is required in order to participate in the online round.

  • The decision of judges is final and binding.

Judging Criteria:

For debugging round:

  • This round will have a time limit of 45 mins.

  • Points will be given based on the following factors - 

    • The closeness of the output with the required output, 

    • Operation conditions, and 

    • The number of components used.

  • Also, if the team completes debugging in t minutes, then the team gets additional points of (45-t)*10.

  • Virtual money = Total points.

For the circuit design round: 

  • Same factors as stated in the second criterion above.

  • The neatness of the circuit.

  • Virtual money that is left.

Sample Problem Statement for Round 3:

I am an X dimensional body. I can see a point, I can see a line, I can see a square, but I can't see a sphere. I am great, because I have n sides such that n = Smallest perfect number - sqrt(n). I am made of 2 sets of members: ones who meet and ones who don't. The ones who meet have all their parameters alike. Find me!

Design a waveform generator using an op-amp that generates this waveform at X kHz.


1) How many participants are allowed per team?
A maximum of three participants are allowed per team.

2) Do all participants have to be from the same college?
No. Members of a team can be from different colleges.

3) Are there any prerequisites for participating in this event?
Just a basic knowledge of electronics will suffice for participating in the event.

4) Is UG-PG collaboration allowed?
Yes. UG-PG collaborations are allowed.

5) When will I be notified if I am selected for the next round?
As soon as the online round is complete and evaluation is done, you will be intimated over a phone call/email, if qualified.
