Opt out before group-2

If you have covid symptoms then you can opt out without submitting any proof. It's a self declaration opt out scheme.
If you opt out then you have to chose option
a. jan/feb 2021
or
b. may 2021

The options mentioned in opt out declaration form doesn't fit me.. Does that mean I have no option to opt out and write the exam compulsorily?

It's a self declaration form. ICAI is not asking for any supporting documents. It means you may opt out if u have cough, cold, body pain etc.

Kya aaj mai opt out kr sakta hu

Yes, you can

In case the student appears for some of the papers in a particular group and subsequently he/she opts out for any of the reasons as mentioned in conditions described by ICAI, then he/she has to appear for all papers of the Group in the next examination cycle i.e. shifting of some of the paper(s) of the same Group is not allowed;
