Hi Rini

By clearing JEE Main and getting a good rank like upto 2,24, 000, you can appear in JEE Advanced exam.

JEE Advanced exam is the entry door to IIT's which are the premier most engineering colleges across the country.

However, if you qualify only in JEE Main, you can apply for admission to NIT's, IIIT's and CFTI's.

Yet again, if not a government seat, you can apply for some private admission on the basis of JEE Main scores.
