Hey kavya!

Although different exams have different exams. And since you have not mentioned the name of exam , i consider it to be NEET exam (as it has general rules applicable to almost every exam). So , if you have alreafy got your documents verified in the first round of counselling , there is no need to get them verified at the second round of counselling. Instead , you have to report again at the document verification centre but just to pay your seat acceptance fee.

Hope it helps!
