Jai, first off, there can be 3 reasons why a rank might not have been assigned in KCET:

1. Your 12th marks missing
2. You must have marked the code inversion wrong
3. Revaluation of your 12th means your marks must have changed and a new rank needs to be assignment.

So technically, these 3 pointers only can happen from a Candidate's side and not KEA's. Second,  once you correct this error, it takes atleast 3-4 business days to assign a rank. Third, we at "Careers360" are no way authorised to force an authoritative body to take an action. We are an education platform wherein we "help students with their queries regarding their Careers and Edcuation". We are not a complaint forum and we do not take the feedback to the Authorities in question. So all we can suggest is reach out to the KEA helpdesk at: keauthority-ka@nic.in . Mail them from your Registered email id. Mention that you have missed mentioning your QE marks initially but you updated them now and are awaiting your Rank. They will respond.
