i have sc certificate which was made 2020 should i renew it for jee 2022

Hello Aspirant,

If your SC certificate is not going to expired before June 2022 then you can definitely use it for JEE-Main 2022 application and once it will get expired you can renew it but if it is going to expire before June 2022 then you should apply for the renewal of it as soon as possible. Also note that it should be of similar format as available on the official website of JOSAA :-

In case if you don't get your reserved category certificate for SC category before the application period of JEE-Main 2022 then then you can submit the undertaking which declares that you will submit the original and valid caste certificate later on at the time of admission. Undertaking will be released along with the official information bulletin of JEE-Main 2022.
