First you have to complete the whole course of Arduino and after 8 weeks you will be qualify to receive certificate. Your Event Coordinator will inform you about that. Learning is important. All the best to complete the course and master the skills.
Also, request you to do not post such questions on Technical Forum of ST IIT Bombay. This forum is designed specific to answer technical queries.
Thanks and Regards,
Ohk ma'am , thankyou very much for the response
