I took admission in the college alloted in 1st round and now I want to take part in 2nd round counselling but its not taking registration not even showing choice filling college list in ug counselling ayush up 2020?
You have confirmed your admission that's why they are not showing your name anymore. If you have reserved your seat then you could have participate in 2nd round.
I hope my answer helps. All the very best for your future endeavors!
