A national beginner-friendly cybersecurity training and Capture The Flag championship for school students (Grades 7-12), run by Amrita Vishwa Vidyapeetham with Team bi0s; it has reached over 20,000 school participants from 23 states over five years.
Students learn through the bi0s wiki, free live trainings and a practice-challenge archive, then compete in an individual online CTF; top scorers win prizes and exclusive training, and all scoreboard participants get digital certificates (a certificate of appreciation above a score threshold). Beginner-category prizes are only for participants without prior CTF experience. Past sponsors include several technology companies.
