Congratulations guys 🙂
This will be counted as your first attempt.
More details to follow soon. The things are not completely clear yet. Still, No need to worry.
P.S. I am unaware of codes to be used while filling forms. However, I am posting the queries as it is, anybody having any idea, can reply to those queries. However, I would request you to get in touch with CBSE. Even some coaching centres have dedicated staff for that matter.
If anybody can write a post on how to fill the exam form, that would be really helpful. I would post on his/her behalf. If you people have any other thing to share, you can write about that as well.
Happy Studying 🙂
