Hi,

As an All India Rank of 2591 in JEE mains is a great rank, so you can surely be eligible to sit for JOSAA counseling given if you satisfy the eligibility criteria for it that is you must have secured at least 75% marks in 12th class.

So to get a seat in any round of counseling you must freeze your seat then only you will be alloted with a seat in any college. So if you remember freezing a seat then you must have got one for you. 

If you don't get a seat then you should go for another round of counseling at the reporting centre and freeze your seat. Otherwise you won't be able to get the college.
