Hello Aspirant,

As you have not mentioned about name of examination for which you are concerned so it is little bit difficult to help you with an accurate information. However if we consider your profile then you are an engineering aspirant so you might be concerned for JEE-Main 2021.

So if you don't have EWS certificate then you are to eligible to get reservation in that but if you are pretty sure of getting your EWS certificate by Jan '21 then you can apply for JEE-Main '21 under EWS category. It is to be noted that applications for January session start in moth of September but for Jan '21 it will be little late due to these unavoidable circumstances.

I hope this information helps you.

Good Luck!!
