Hello Chhavi

Document verification is one of the most important procedure during admission in any college or university. If you have appeared in first round of counselling, then you must have had all the documents you needed there and verified them. So, in second round as well you need to give all the required documents asked by any institutions at the time of counselling. Whether it may be 1st or 2nd or 3rd round of counselling you must have all the documents mentioned at the website of the board of counselling. So you need to get your documents verified in the second round of counselling too.

Hope it helps you.
