Hello aspirant,

If your SC certificate won't expire before June 2024, you can use it to apply for JEE-Main 2024. Once it expires, you can renew it. If your SC certificate will expire before June 2024, you should apply for a renewal as soon as you can. Also keep in mind that it should follow the structure that is used on the JOSAA website.

You can submit an undertaking that states that you will later present the original and valid caste certificate at the time of admission if you don't receive your reserved category certificate for the SC category before the application period for JEE-Main 2022.

Thank you

Hope it helps you.
