Hii Poojitha,

Hope you are doing great. As per my knowledge registration can be done only once. During second counselling you have another chance to select the colleges as per your preferences if you have cancelled the first phase seat and if you don't get the college you want.

I hope my answer will help you.

If you want to predict the college for your rank you can go through the below link:

Thank you
