Hello Vijay,

Caste and income certificate are important documents whether you are applying for seeking admission in any College or applying for scholarship. Based on your income and caste, the government decides that whether you should be given scholarship or not.  The validity of income and caste certificate if for three years, so if your certificate is generated in 2020, so you are very much eligible for applying for session 2021-2022 as your certificate is valid for three years.

So, you can apply for your post matric scholarship on the basis of your income and caste certificate which you have.

Let me know if you have any questions. Thank you!
