In the Manipur Board 12th exams, practical examination marks are essential for passing subjects with practical exams. To pass such a subject, a student must score at least 21 marks in theory and 12 marks in practical, and achieve a total of 33 marks. If either component falls short, the subject will not be considered passed, and the subtotal will remain blank. Thus, practical marks directly impact the overall grade by determining if a subject is counted towards it.
