Dear Aspirant !

Hope you are doing great ! No it's not good , if you want to use ews (economically weaker section ) certificate then you have to make it ,you father ews certificate will not work here in anyway. Doesn't matter if you are 18 years old or above it . Only your ews certificate will work . Also there are some conditions of ews certificate like it should be latest not before than 01 April 2022 if you want to use it in 2022 for education purpose .

Hope you find it helpful !

Thanking you !
