Hi sir, I have given neet registration number during kcet verification should I have to register it again in online.

Hi Yashaswini,
Hope you are doing well. No, it is not necessary to register once again if you have given the NEET registration number during document verification. The officials who are present during document verification will register your registration number then and there itself. There is no need for you to register once again and it may also create some other problems. I hope you got the point after reading this answer.

All the best.
