Hi

Class 11th examination is a school level entrance examination so it totally depends upon school when they conduct the examination and it varies from school to school.

So you can ask your school teachers regarding the dates for your class 11th final examination

But generally academic year ends in March so most of the school conduct final examination in the month of March so it can be expected that your class 11 final examination may be conducted in the month of March .

Don't worry about dates, just focus on your preparation as generally students are informed and given the dates of examination at least one month before the exam

Thank you
