Why This Matters for You
- Timely registration ensures your seat is confirmed, subjects are locked in, and you can start proper preparation.
- Paying fees early means you won’t incur extra cost or miss cut-off windows — very important for students with tight budgets.
- Being on time gives you greater choice for subject combinations, exam centre location etc.
- This open schooling pathway (via NIOS) offers flexibility and recognition for students who could not complete the standard schooling route — utilising it effectively can open educational/career options.
