No, you cannot appear for the Class 12 UP Board English exam if you did not select English in your registration form . The subjects chosen during registration are final, and the board only issues admit cards for registered subjects . However, you can contact your school or the UP Board regional office to check if corrections are possible. If changes are not allowed, you may need to reappear next year or opt for improvement exams. Always verify subject choices carefully during registration to avoid such issues.
