Hello,

In 2026 if you are giving 12th board exam, you must have a valid DOB with year 2007 or 2008 or in some cases you can have a year less than but not more than 2008, it mainly depend on the date of admission and the year you started studying.  Some have joined school at the of 3yrs or some have joined at 4yrs. So it differs, but you must have your  year of birth between 2007-2008 for appearing board exams in 2026.
