How can i get into IIT?? what is the application process. Actually m frm a very rural background and want to study in a IIT because we cant afford money for my engineering in private colleges. please help me

dear shyam 
for entering into iit , frst of all u need to score 75 percent in class 12^th board exam ( any board ) , and in case any catagory attached on your name , then it will be lesser , 
after that apply for jee mains , and attempt that , u need to score at least 140+ to qualify it and to attempt jee advanced , 
and apply for jee advanced and attempt the exam , there score at least 40 percent mark of the paper and get rank within 10,000 , and u are in .. 
HOPE IT CLEARS
