Ahead of the final against China's Ren Cancan, Mary Kom predicted: "If she is world champion, then I am also world champion. It's going to be an easy final."
She duly defeated her Chinese opponent 14-8 to avenge a semi-final defeat at the 2010 Asian Games in Guangzhou.
MC Mary Kom is mixing up her normal preparations for London 2012
The five-time world champion has moved to the city of Pune from her usual base in Patiala, Punjab to be with British coach Charles Atkinson for a month.
"I wanted to train alone... away from all the distractions," said the fighter. "I have been going through the same routine for the last 10-11 years. For the Olympics, one has to break away from the mould."
"Today was not my lucky day," she said after losing to Argentina's Pamela Paoloa Benavides in the quarter-finals. "Before the bout I had a minor ankle injury. The world championships are the qualifiers for the Olympics so that is the main tournament and I will do my best for my country there."
Mary Kom also added her voice to a recent debate about whether women boxers should wear shorts or skirts at next year's Games: "The tennis players wear skirts and the badminton players are wearing skirts so why don't the boxers wear skirts?"
She outpunched Pinki Jangra 13:9 to secure the flyweight title at the Indian Championships in Bhopal. She later revealed how she deals with the pressure of representing a country with over a billion inhabitants.
"If I think about the millions of hopes resting on me, it will be difficult to box under those circumstances," she said. "When I am in the ring I just think of the bout and the opponent."

After seeing his wife beat North Korea's Kim Myong Sim to the title, Omler Kom said: "It was an emotional decision for her to leave before our son's surgery but she promised me she would get the top spot, and I am happy that she did".
