NDA Preparation — Cheatsheets
Exam structure
|---|---|---|
| Mathematics | Algebra, trigonometry, geometry, calculus, vectors, statistics/probability | 300 |
|---|
| GAT — English | Comprehension, grammar, vocabulary | (part of 600) |
| GAT — General Knowledge | Physics, chemistry, general science, history, geography, current affairs | (part of 600) |
| Total written | — | 900 |
| SSB interview | 5-day: psychological tests, group tasks, personal interview | Pass/fail + merit |
(needs verification — recheck against current source: UPSC periodically revises exam pattern and marks distribution.)
Mathematics topic list

| Calculus | Limits, continuity, differentiation, integration, basic differential equations |
| Other | Vectors, statistics and probability |
NDA vs. CDS quick distinction
|---|---|---|
| Entry point | Post-Class XII | Post-graduation |
|---|
| Candidate age | ~16.5–19.5 | Older, graduate-level |
| Syllabus level | Class XI-XII / foundational | Graduate-level |
| Conducted by | UPSC | UPSC (separate exam) |
SSB process quick reference
|---|---|
| Psychological tests (TAT, WAT) | Personality traits, thought patterns (projective methods) |
|---|
| Group tasks | Leadership, teamwork, problem-solving under pressure |
| Personal interview | Background, motivation, general awareness depth |
Officer-Like Qualities (OLQs) — key traits assessed
| Trait | What it looks like in practice |
|---|
|---|---|
| Leadership | Taking initiative appropriately without dominating |
|---|
| Social adaptability | Listening to and building on others' ideas |
| Determination | Composure under time/physical pressure |
| Communication | Clear articulation of ideas in discussion |
(needs verification — recheck against current source: full OLQ framework set by the Directorate General of Recruiting, periodically revised.)
Preparation timeline principle
|---|---|
| Mathematics | Concentrated, practice-driven study close to exam |
|---|
| GK — foundational | Early, systematic review |
| GK — current affairs | Continuous, intensified near exam date |
| SSB/OLQ readiness | Long-term, well before written exam (leadership experience, fitness) |
