Hi, so basically the following documents are needed for admitting in any college. Just keep all the documents with you.

• Certificates of all examination since highschool onwards and domicile certificate.
• Category/Subcategory certificate, in case of availing reservation of any kind.
• Transfer certificate/ Migration certificate (These certificates might be required as original).
• Character certificate as issued by the principal/ head of the college last attended (required as original)
• Affidavit on stamp paper, for gap period if any

These are the major documents that you should keep with you. And if any other document is needed the college will inform you. However these documents are sufficient for the admission.

Hope this is helpful.
