Introduction
What is Defence Study
Defence Study is a free defence information website and community for Indian defence aspirants.
It brings everything you need for a defence career into one place:
- Exam preparation: Guides for every defence exam and entry, covering eligibility, syllabus, exam patterns, strategy and the SSB interview.
- Notifications: Official notification alerts, application windows, exam dates, admit card releases and results.
- Study material: Practice resources, including Previous Year Papers.
- Defence news: Indian Defence News and Global Defence News, covering military developments, defence deals, policy and geopolitics.
- Heroes & Stories: Success Stories of candidates who cleared their exams and SSB, and profiles of those who serve.
Defence Study works on two levels:
- The website (defencestudy.com): Detailed guides, explainers, study material and news, organised by category and exam.
- The community channels: WhatsApp, Telegram, YouTube, Instagram and Facebook, where updates and alerts reach you directly.
Right now, every article and guide on the website is free to read, with no login and no paywall. We may introduce courses or other offerings in the future.
Our mission
Defence aspirants don't lack information. They face too much of it, spread across too many sources, and much of it is outdated, unofficial or contradictory.
Defence Study's mission is to fix that by giving aspirants:
- One place to find exam, selection and career information
- Verified information based on official notifications
- Practical guidance in the form of plans, frameworks and checklists
- Clear explanations of how each selection stage works and what assessors look for
The goal is simple. When you have a question about a defence exam, entry or selection stage, you should be able to open Defence Study and get a clear answer, along with your next step.
What we are not
Know this before you use Defence Study.
| Defence Study is not... | What that means for you |
|---|---|
| A coaching institute | No classroom coaching, live batches, one-to-one mentorship or SSB simulation training. We publish content. |
| An official body | We are not affiliated with UPSC, the Indian Army, Indian Navy, Indian Air Force, Indian Coast Guard, SSC, NTA or the Ministry of Defence. |
| An exam authority | We don't conduct exams, issue admit cards, declare results or set eligibility rules. |
| A paid service today | All current content is free. If we introduce courses in the future, they will be clearly announced. |
| A selection guarantee | No one can promise selection. We show you the process; the preparation is yours. |
Tip: If anyone contacts you claiming to be from Defence Study and asks for money in exchange for selection, it isn't us. Report it.
Audience
Who Defence Study is for
Defence Study is built for defence aspirants: Indian candidates preparing for, planning to appear for or exploring defence exams and selection processes.
This includes aspirants targeting NDA, CDS, AFCAT, Agniveer, Indian Navy entries, the Indian Coast Guard, CRPF, BSF, CISF, the SSB interview, technical entries, NCC Special Entry, the Territorial Army, RIMC, Sainik School and other defence entries.
It covers first-time and repeat aspirants, school students and working professionals, officer-level and soldier-level entries.
Parents, teachers and mentors
Defence Study also serves people who support aspirants: parents, teachers, mentors and anyone researching a defence career for someone else.
Content for this group focuses on plain-language explainers: what an exam is, who is eligible, how the process works and what the career looks like. This is especially relevant for RIMC, Sainik School, NDA and Agniveer.
Basic Eligibility
General eligibility requirements
Every defence exam has its own detailed rules, but almost every entry checks the same basic areas.
| Requirement | What it means |
|---|---|
| Nationality | Candidates must be Indian citizens. Some entries also accept certain other categories, as listed in the official notification. |
| Age | Every entry has a fixed age window, calculated on a cut-off date given in the notification. |
| Education | Each entry has a minimum qualification, from Class 7 for school-level admissions to graduation for officer entries. Many entries allow candidates in their final year or appearing for board exams to apply. |
| Subjects | Some entries require specific subjects, such as Physics and Maths for flying, naval and technical entries. |
| Marital status | Most initial entries, including NDA, CDS and Agniveer, require candidates to be unmarried. |
| Gender | Many entries are open to both men and women, but vacancies and conditions vary by entry. |
| Physical standards | Minimum height, weight and chest measurements, and fitness tests such as running, depending on the entry. |
| Medical standards | Eyesight, hearing, general health and other medical conditions are checked before final selection. |
| Character and documents | Valid educational certificates, identity proof and a clean record are required at the verification stage. |
| Attempts | Most defence exams don't cap attempts directly. Your age window decides how many chances you get. |
Tip: Age limits, qualifications, relaxations and physical standards change between cycles and entries. Always confirm the exact rules from the latest official notification before applying.
How defence selection generally works
Selection steps vary by entry, but most defence recruitment follows the same broad path.
| Stage | What happens |
|---|---|
| Notification | The conducting authority releases the official notification with eligibility, vacancies and dates. |
| Application | Candidates apply online within the application window. |
| Written or online exam | Tests subjects such as Maths, English, General Knowledge and Reasoning. Some entries shortlist on academic marks or JEE Main scores instead. |
| SSB or interview (officer entries) | A five-day SSB or AFSB assessment of Officer Like Qualities. Some entries use an interview board instead. |
| Physical tests (soldier-level and CAPF entries) | Running, physical measurements and fitness events. |
| Medical examination | A detailed check against the medical standards of that service. |
| Merit list and joining | Final selection is based on merit, followed by joining instructions for training. |
