Students who believe their exam papers have been evaluated unfairly should first follow the grievance procedure provided by their school, college, university, or examination authority. They can usually apply for revaluation, rechecking, or scrutiny within the prescribed deadline and pay any applicable fee.
If the issue is not resolved, the student can submit a written complaint to the examination controller, grievance committee, or head of the institution, clearly explaining the concern and attaching relevant documents such as the mark sheet, answer-sheet copy, and revaluation request.
Students should keep copies of all applications and correspondence. If the institutional process does not provide a satisfactory resolution, they may consider approaching the appropriate education authority or seeking legal advice, depending on the circumstances.
