Hey John

I do not understand what you mean by "ex regular" here. If you mean that you have fropped a year or two then it is okay as you acn still give government job exams. If you have given the 12th board papers again (because of reasons like you could not pass in a few subjects at one go or you did not give all of th epapers in one go) then too you are eligible for Government Job Exams deepnding on which exam you are talking about. I  am giving you a link from where you can check your eligibility for Odisha Government Jobs https://gaodisha.gov.in/node/900 . All the best!
