What is the minimum rank in jee mains to addmission government btech college??

Dear student,
There are many government colleges that take admission on the basis of jee mains score. Therefore it is nearly impossible to tell that what minimum marks you should score to take admission in a government college. Also if you wish to ask about admission in nit/iiit/gfti then you must qualify jee mains, and then based on your marks you would get admission in these Institutes. Please mention a particular college because there are thousands of government colleges that take admission on the basis of jee mains. So it would be nearly impossible for us to answer your query. Even if a person doesn't qualifies jee mains then even he/she can get other government colleges except nit/iiit/gfti.
