Hello there, hope you are doing good!

I would like to tell you that yes you can withdraw you NIT seat in JOSAA round 5 2020. As the counselling does go up to more rounds I suggest you withdraw your seat before the last counselling occurs as then you would not receive the refund for your counselling fees. The last date for you to withdraw your seat is 6th November 2020.

Hope you found this answer helpful.

Good luck for your future!
