The boarding school, run by monks of the Ramakrishna Mission and Math on the outskirts of the city, had 76 candidates for the HS exams - all in the science stream.
"Eight of our students are in the top ten list. They are in 6th, 7th, 8th and 10th ranks. Our school average is 92.10 per cent," school headmaster Swami Vedapurushananda told PTI.
None of the students have secured below 75 per cent marks while a majority 59 of them have bagged 90 per cent plus scores.
The monk credits the secret behind the stupendous success of his students to a number of factors including a disciplined lifestyle in a residential school where most students are admitted in younger classes.

None of them have access to distractions like TV sets or mobile phones in the campus where every morning begins with meditation and prayer sessions.
"They meditate and pray again in the evenings also which improves their concentration power. They grow up imbibing the ideology of Ramakrishna Paramahansa and Swami Vivekananda," Vedapurushananda said.
