Good afternoon here's the details

CBSE (Central Board of Secondary Education)

Yes, but with limits:

July Session: You can appear for 1 subject (or 2 in Class 10) alongside compartment students

Next Year (Feb–March): You can appear for up to 5 subjects as a private candidate

Important: You cannot be enrolled in college if you're giving improvement exams

NEP 2020 Reform (All Boards from 2026)

As per the CBSE Draft Scheme:

Students will be allowed to take board exams twice in a year

This applies to Class 10 and 12, starting from 2026

The best score from the two attempts will be considered

State Boards (WBBSE, UP Board, etc.)

Most state boards do not currently allow two improvement attempts in the same year

You usually get one chance in the year following your board result

Some boards may allow compartment + improvement separately, but not two full improvements

Hey Konpal:)

Unfortunately,no,you can't write improvement exams twice in the same year.

They are usually conducted a few months after  the regular boards results.You can appear for one or more subjects in that attempt to improve your marks .If you're still not satisfied, you'll have to wait until the next year improvement exam session
