It’s okay to face setbacks; what matters is how you move forward. Since you gave your CBSE Class 12th exams in 2025 but got compartment in Chemistry and Maths, and unfortunately couldn’t clear them even in the July attempt, choosing to reappear through NIOS in 2026 as a private candidate for all subjects is a smart and responsible step. NIOS is a valid and recognized board, and many students take this route to improve their performance or get a fresh start. Stay focused, prepare well this time, and give your best. One tough year doesn’t define your future.
