Hey!

Stray/mop up round in neet counselling is conducted to fill out the vacant seats left in the colleges. And there is no such list where you will find the colleges with their vacant seats. So, for this you need to visit the each college's official website separately and fill out the registration form. Suggestions are to choose those colleges for which you are eligible. The colleges have their own stray vacancy list and some of the colleges also allots the seats on merit basis.

Also, the seat matrix for stray round will be known once after the mop up round is over.

Hope I answered your query, thankyou!
