Hi Sonal.
I contacted UCLA and here's what they told me:
1. They asked me to post sealed envelopes of my transcripts as received from the Uni/college.
2. Also, SPPU does not publish the grade scale on the transcript for B. Com. Degree. So, they told me to send the documents as they are.
Also, I have sought an extension for the degree certificate submission. SPPU said they will only provide attestation on xerox copies of certificates and not an original degree certificate for the purpose of submission. I have asked UCLA AdCom if they're okay with it. Awaiting confirmation.
Hope this helps.
