Dear candidate........,

Well, admission into any engineering college through the score of JEE MAINS is done through counseling process i.e, JOSAA COUNSELING. But there are also different constituent and government engineering colleges that gives admission on the basis of JEE MAINS rank. For that you have to apply for the local counseling occuring in that particular state. There are also some private institutions that directly take students on the basis of their mark depending upon the availability of seats.

Hope this helps you out........

Best of luck:)
