kya mai apna 12th board exam hiindi and english dono medium me de sakta hu but mai 11th me english medium choose kiya tha bihar board se
HELLO,
NO, you are generally not allowed to appear in both Hindi and English medium for your class 12th board exams , as according to Bihar Board Rules , your medium of examination is determined during your registration process for class 11th and 12th. You can choose one medium and write all your subjects exams in that language , except for the language paper themselves .
Hope this helps!
