I am getting 80 marks ..... Will i be able to give advance?

Hi Arshi.
Greetings.
It depends totally upon your caste category.  If you belong to general category, then you are not qualified. But, if you are from SC,ST or OBC, then you qualify for advance.
Thank you. All the best.

Dear Arshi,

The exact status will be known once the result of JEE Main 2018 is declared. Whether you will qualify for JEE Advanced or not will also depend on the category cutoff of JEE Main for JEE Advanced. As per the last year's stats, the qualifying cutoff for appearing in JEE Advanced was 81 for Gen, 49 for OBC-NCL, 32 for SC, 27 for ST and 1 for PWD. So, it depends on the cutoff of this year which may vary a few points. Considering that, you may be on margin and may not qualify.
