NDA vs CDS vs AFCAT: Which Exam Is More Difficult?
It is difficult to declare one examination as universally easier or harder because the difficulty depends on the candidate’s educational background, preparation level and strengths.
NDA may be challenging for school students because it requires preparation across Mathematics and GAT while simultaneously managing school studies. CDS requires graduate-level preparation, while AFCAT has its own subject combination and competitive selection process.
The better approach is to identify your current qualification, strengths and career goal rather than choosing an examination simply because you believe it is easier.

All three pathways involve more than a written examination. Candidates must successfully clear the applicable subsequent stages and satisfy medical, merit and other requirements.
- NDA: Written Examination → SSB/Services Selection → Medical Examination → Final Merit and Joining as applicable.
- CDS: Written Examination → SSB Interview → Medical Examination → Final Merit and Academy Joining as applicable.
- AFCAT: AFCAT Written Examination → Applicable Selection/AFSB Stages → Medical Examination → Final Merit and Training as applicable.

- Teamwork.
- Leadership potential.
- Decision-making.
- Confidence.
- Self-awareness.
- Problem-solving ability.
