Hey Zaheer

As per 2018 cutoff,you are eligible for Advance.To get Govt college chance is quite difficult.

Hey! Hi Zaheer.

By the marks you have scored in JEE MAIN 2018, YES you are eligible to appear in JEE Advance. And about your next question, it Completely depends on the Rank you get in JEE Advanced. If going by JEE MAIN 2018 rank, IT IS QUIET DIFFICULT TO GET A GOVERNMENT COLLEGE.

Hope it Helps.

Thanks.
