How to Self-Attest Your Documents Correctly

Self-attestation is a simple process, but doing it incorrectly can lead to the rejection of your application form.

Steps to Self-Attest:

1. Take a clear photocopy (Xerox copy) of your original document (e.g., your 10th marksheet or degree certificate).
2. On a blank space at the bottom of the photocopy, clearly write "Self Attested" by hand.
3. Put your signature directly below the "Self Attested" text.
4. Write your full name below your signature (exactly as it appears on your certificates).
5. (Optional but recommended) Write the current date next to your signature.
6. Scan this signed photocopy using a mobile scanner app or a flatbed scanner. Save it in the required file format (usually PDF or JPEG as specified by the portal).

Practical Tips for Uploading Documents

• Combining Marksheets: For the "all semester marksheets" field, you must combine all your marksheets into one continuous PDF file. You can use free online tools like IlovePDF or Smallpdf to merge them, but make sure each page is self-attested before you merge them.
• File Size Limits: Keep an eye on the file size limit mentioned on the portal. If your merged PDF is too large, use a PDF compressor tool to reduce its size without losing readability.
• CGPA Conversion: If your college marksheets use CGPA or CPI, check your university guidelines and obtain the official conversion formula document. Self-attest this formula sheet and upload it in the designated section.
