Hey I had applied for CAT Exam and took the exam and scored 99.12 Percentile. I noticed just now that eventhough I clicked the NCL-OBC option, I uploaded my Community certificate instead of OBC Certificate. I have got calls from IIMK, IIMV, and JAP process for now. In all the process, my community was locked to NCL-OBC and I was not able to change it. So will all the other colleges consider me as OBC? Or will I be considered as general Category. Please answer as soon as possible because Im yet to fill some forms. Thank You!

You selected NCL-OBC in the CAT form, so colleges will see you as an OBC candidate for shortlisting.
However, for final admission, they will ask for a valid OBC-NCL certificate.
Uploading a general community certificate does not fully prove OBC-NCL status.
If you can submit the correct OBC-NCL certificate later, you will be treated as OBC.
If you fail to submit it, you may be shifted to the General category.
Your CAT score and calls will not be cancelled because of this mistake.
It would be best for you to contact the IIM admission office and explain the issue early.
