Hello aspirant,

If you have entered the wrong PU registration number, then you need not to be worried about that, because you can change it when the registration window will open. Candidates can correct/modify their wrong entries during the correction time . No offline mode will be entertained to make correction. After making the required correction, candidates must take printout of the application for further use.

Further, if you wish to know more further details regarding the KCET examination and other relevant details you can follow the below mentioned link to know more about it : https://engineering.careers360.com/articles/kcet-exam-dates

I hope that this will help.
