Hello aspirant,

You won't face any consequence if you have used your BC certificate in the place of OBC. Because OBC & BC is often recognized as the same. Get to know this fact that, BC means Backward Classes having sub categories like BC-A, BC-B, BC-C, BC-D and BC-E whereas OBC means Other Backward Classes. So don't get worried about those short terms where you find with a just difference of O only. Both are considered as same.

Hope, this information helps you.
