Hey there,

Greetings!

Hope you’re having a great day.

I would like to inform you that yes you are eligible for sitting in the next session of JEE Mains which is in April even though you haven't attempted the first session provided you score your best in the second session so it will absolutely cover up for the unforeseen circumstances in the first session.

Let me know if you have further clarifications by mentioning it in the comment section below.

Have a nice day!

I wish that you have a bright future ahead.

Thanks.
