sorry bro but you won't get any iits, however you can get nits(will have to compromise with branches) and iiits. If you really want a good government college.then take a year's drop and prepare for jee advanced..believe you me.either you can labour very hard for 9-10 months(for jee advanced) or you can labour next 5-10 years(becuase the starting salary of an iit computer science engineer is something that takes 5-10 years for a normal dude to achieve....)
