Dear Aspirant 

You don't have to worry if you have claimed rural weightage in your application form and if you don't have rural weightage certificate. As soon as registration for counselling begins they will upload a notification for those candidates who has made such errors. They will upload a paper which you need to download and take printout of it and upload it after doing your signature below the statement which declare that you don't have rural weightage certificate, so you are withdrawing your complain. Hence after doing same you will not be considered under the benefits of rural weightage.

Good luck for your admission :) 

Feel free to ask if you have any further queries.
