Students who have passed all subjects except one in the Uttarakhand Board Class 12th examinations are eligible to appear for a compartment exam in the failed subject, such as Mathematics. The Uttarakhand Board allows students who have failed in one or two subjects to take these supplementary exams as an opportunity to improve their results. Registration for the compartment exams is typically conducted online, with forms becoming available in May. By passing the compartment exam, the student is declared as having passed Class 12th overall and is eligible to receive the official pass certificate without the need to repeat the academic year.
