About 27 percent seats are reserved for Other Backward Classes (OBC) belonging to non-creamy layers in IIM's for admission through CAT.

At the time of selection process or interview rounds, you will have to show the original document and copies to be submitted at IIMs during the final admission process. In case you are unable to submit the documents, you may not be considered under reserved categories.

The cutoff and admission process is slightly separate for reserved categories in IIM's so accordingly you can apply for the further admission process.

Good Luck.
