  14. A category candidate belongs to jarkhand but appeared 10+2from UP his state code of eligibility is UP his home state will be UP as per cbse but his category dose not fall in category list of UP so whether he will get category benefits or not.if not then he has to appear10+2from jharlhand to avail this benefit is he not a sufferer.

    1. He belongs to Jharkhand. If he is an SC, he will be an SC of Jharkhand only. If he had given JEE MAins in Jharkhand his state of eligibility will change. After all you need an SC Certificate from Jharkhand SC Community to be its SC. Remember that!

      1. So,there wont be any problems in those cases as requirement of residence certificate?

  15. Homestate quota is not clearly defined candidates of resserve categories don’t get benifit of there resservation as they don’t fall in category list of that state to which they have state code of eligibility.
