What Is NDA?
NDA/NA is a 10+2-level officer-entry route conducted by UPSC for eligible candidates seeking training through the National Defence Academy or Naval Academy pathways subject to academy and service rules.
Eligibility Checklist
- 10+2 qualification or appearing status where permitted.
- Required subject combination for the selected academy or wing.
- Age within the official window.
- Nationality and marital-status conditions.
- Physical and medical suitability.
- Accurate education and identity records.
NDA Exam Pattern
The written examination commonly includes Mathematics and the General Ability Test. Use the active UPSC notification for final paper structure, marks, timing and instructions.
NDA Syllabus Areas
- Mathematics: algebra, trigonometry, coordinate geometry, calculus basics, matrices, statistics and probability.
- English: grammar, vocabulary, comprehension and usage.
- General Knowledge: physics, chemistry, biology, history, geography, polity, current affairs and defence awareness.
SSB Preparation
- Understand the purpose of screening, psychology, group tasks and interview stages.
- Build clear communication and self-awareness.
- Practise group participation without memorised behaviour.
- Know your education, interests, responsibilities and motivation clearly.
- Maintain physical fitness and routine discipline.
Medical and Physical Standards
Do not assume general fitness guarantees medical suitability. Academy and service standards can include vision, hearing, body measurements and other medical conditions. Verify official standards early.
Documents to Keep Ready
Prepare 10th certificate, 12th certificate or appearing proof, ID, photograph, signature, application form, admit card and later-stage SSB or medical instructions.
120-Day Preparation Plan
- Days 1–40: build Mathematics and English fundamentals, start current affairs and fitness.
- Days 41–80: practise NDA-level questions, GAT MCQs and timed sections.
- Days 81–120: take full mocks, revise formulas and build SSB awareness.
Common Mistakes
- Ignoring academy-specific eligibility.
- Preparing only GAT and neglecting Mathematics.
- Waiting until after the written result to understand SSB.
- Ignoring medical standards.
- Using unofficial age or eligibility claims.
