Dear,

You have a very good chance to get admission in IITs like IIT Delhi, IIT Bombay, IIT Madras, IIT Kanpur etc. For this, you should apply the application form of IITs individually. Some of the IIT M.tech admission forms will be out before the GATE result and most of the IITs application form come after the GATE result. So you should regularly check the IITs website.
