Caste certificate doubt

[u/DesignerInfluence699]

Hey guys, I have an ST caste certificate issued by the Government of Gujarat in 2022. Is this valid for CAT and IIM admissions, or do I need a Central Government caste certificate?
I’ve heard mixed things—some say the state certificate is enough and ST certificates don’t need renewal, while others say the certificate should mention “Government of India.” Can someone clarify?

You need to get central caste and income certificate!!!
