You most likely will still be considered for passing based on the information you provided.

The CHSE Odisha board requires a minimum of 33% marks in each subject (including theory and practical) and an overall aggregate of 33% to pass class 12 exams.Since your failure is in the optional subject, and assuming all other subjects meet the minimum marks (33%), you should be okay.

You need 33% marks in each subject (5 main subjects + 1 optional). If you have 33% or above in all your main subjects, even if you failed the optional subject, your overall aggregate should likely be above 33% (considering the marks of all 6 subjects).

However , to be absolutely certain, it's best to confirm this directly with the CHSE Odisha board or the college you are applying to.
