Hello , 

As your query is you applied for Karnataka MBBS round 1 of counselling but didn't get any seat. And you want to know whether you have to go with document vertification in 2nd round of counselling and visit the centre again .

I want to tell you that there is nothing like re verification of Documents again in other rounds of counselling but definitely you must visit the counseling centre. This might not be a must condition but I am suggesting you this anyway because your presence at the counseling centre makes a great impact on the choice of your college. 

Seeing you absent they might mark you a college not as per your sale but your presence can change the work and decision. You must definitely visit counselling centre.

Further, if you have any other query regarding the same you can let me know in the comment section below.

I hope your query is solved.

Thank you.
