JEE Main Eligibility

You have to clear cutoff for the eligibility for any state or Madhya Pradesh B.Tech counseling. No worries about attending counselling. A student did not cross cut-off mark means that he is not eligible to appear in JEE Advanced. If a student doesn't qualify, depending on his marks (after normalization), he is provided a rank, for suppose, let us consider the rank provided by you I. e.27000. With this rank, you can get a seat somewhere in an NIT (Though, not the best NIT, but just an NIT). You will be able to attend counselling and the only thing is that, you are not eligible for Advanced.

No, as the admissions are only through JEE Mains. Though, board's marks are only for the eligibility.

If this is your all India Rank, then you'll definitely get in any of the top colleges. If this is your category rank, then you can expect in top 6-11 NIT's. Also, you can go for various good autonomous institutes with home state quota. Refer NIRF rankings for engineering for their performance analysis.

You may get till last round of counselling.
