Yes, every student who has passed 12th and cleared JEE Mains with the least cut-off marks for their category is eligible for JoSAA counselling.

Hello,
Hope you are doing well. If you had not given the NATA examination then there would be less chances that you will get this college but as if you had given the NATA examination and you scored 80 marks minimum ,then you will be eligible to get this college. Please share your NATA score so that I will tell you the exact scenario for this college.

JEE Mains occurs before the results of 12th so there is no such requirement for JEE Mains.

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.
