What is the Exam?
The Combined Defence Services (CDS) Examination is conducted twice a year by the Union Public Service Commission (UPSC) for recruitment into the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), and Officers Training Academy (OTA). As expert mentors at ExamBhai, we recognize that mastering the static General Knowledge (GK) paper is a non-negotiable requirement for cracking this prestigious defense exam. Unlike dynamic current affairs, static GK forms the core foundation of the UPSC question paper, testing your retention of enduring facts about India and the world.
Candidates often struggle with the vastness of the syllabus. This is where a structured static GK compilation becomes essential. By filtering out redundant information and focusing on high-yield topics such as Indian heritage, national institutions, defense technology, and world geography, aspirants can drastically improve their accuracy.

Exam Pattern
Understanding the structure of the question paper helps in time management and strategic guessing. The General Knowledge paper consists of 120 multiple-choice questions carrying a total of 100 marks.
| Paper Name | Duration | Total Questions | Total Marks |
|---|---|---|---|
| English | 2 Hours | 120 | 100 |
| General Knowledge | 2 Hours | 120 | 100 |
| Elementary Mathematics | 2 Hours | 100 | 100 |
Note: Elementary Mathematics is applicable only for IMA, INA, and AFA applicants. OTA candidates appear only for English and General Knowledge.
Each correct answer awards 0.83 marks for GK, while every incorrect answer incurs a penalty of (0.27) marks (1/3rd of the allotted mark). Leaving a question blank attracts zero penalty.

Application Process
The application process for the CDS examination is entirely online and managed through the official UPSC portal. Aspirants must carefully navigate the registration stages:
- One-Time Registration (OTR): Candidates must register on the official UPSC OTR platform by entering their personal details, basic educational background, and contact information.
- Application Form Submission: Log in using your OTR credentials, select the active CDS notification, and choose your preferred academies (IMA, INA, AFA, OTA).
- Fee Payment: Pay the requisite application fee of INR 200 (female candidates, SC, and ST candidates are exempt from fee payment) through net banking, debit/credit card, or cash challan.
- Center Selection: Choose your preferred examination center from the available list across India. Prompt submission ensures allotment of the first-choice center.
- Final Printout: Verify all filled details and submit the application. Download and preserve a printout of the confirmation page for future reference.
Preparation Strategy
Cracking the static GK section requires a disciplined, multi-layered approach rather than random reading. At ExamBhai, we recommend dividing your preparation into three distinct phases:
- Phase 1: Conceptual Foundation: Read standard textbooks such as NCERTs for history, geography, and science. Do not jump straight into compilation books without understanding the underlying context of historical events or geographical phenomena.
- Phase 2: Compilation Mastery: Utilize a consolidated static GK compilation to memorize high-frequency tables such as national parks, international organizations, dance forms, and nuclear power plants. Create short, mnemonic-based notes for rapid revision.
- Phase 3: Active Recall and PYQ Analysis: Solve at least the last 10 years of UPSC CDS question papers. UPSC frequently repeats core themes, and analyzing past trends reveals the exact depth required for topics like medieval architecture or constitutional articles.
Consistency is key. Daily revision of static facts combined with sectional testing will build the retention required to clear the cutoff.
Cut-Off Trends
Analyzing previous years' cut-off trends provides a realistic benchmark of the competition level. Based on historical data published by the UPSC on upsc.gov.in, the qualifying marks required to clear the written stage vary across academies:
| Academy | Average Written Cut-off (Out of 300) | Approximate Percentage |
|---|---|---|
| Indian Military Academy (IMA) | 130 - 145 marks | ~43% - 48% |
| Indian Naval Academy (INA) | 120 - 135 marks | ~40% - 45% |
| Air Force Academy (AFA) | 140 - 155 marks | ~46% - 51% |
| Officers Training Academy (OTA - Men) | 90 - 105 marks (Out of 200) | ~45% - 52% |
| Officers Training Academy (OTA - Women) | 95 - 110 marks (Out of 200) | ~47% - 55% |
Keep in mind that candidates must also clear individual sectional cut-offs (typically a minimum of 20% in each subject) to be considered for final evaluation.
