hi,

see since ews certificate is valid for one year at your state authority rules, if the ews certificate has issued on 8-01-2021, then it is valid till 8-01-2022. so in that case you can apply for jee advance exam by using the same ews certificate.

remember, jee advance is the entrance test for iits to admission in b.tech course. you must secure the qualifying cutoff in jee main exam to become eligible to appear in jee advance test.

hope you understand.
