Choosing the right defence exam—CDS, AFCAT, or NDA—is a critical step for aspirants aiming to serve in the Indian Armed Forces. Each exam opens doors to prestigious careers in the Army, Navy, or Air Force, but they differ in eligibility, exam patterns, and career paths. At FPA Exam Prep, we’ve crafted this comprehensive guide to help you understand these exams and make an informed decision with confidence.

What Are CDS, AFCAT, and NDA Exams?

• CDS (Combined Defence Services): Conducted by UPSC twice a year, CDS is your gateway to the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), and Officers Training Academy (OTA). It’s ideal for graduates seeking diverse roles in the Army, Navy, or Air Force.
• AFCAT (Air Force Common Admission Test): Organized by the Indian Air Force, AFCAT targets candidates passionate about Flying, Technical, or Ground Duty roles in the Air Force. It’s open to both men and women and focuses on Air Force-specific careers.
• NDA (National Defence Academy): Also conducted by UPSC, NDA is for young aspirants (16.5–19.5 years) who have completed or are appearing for 10+2. It offers early entry into the Army, Navy, or Air Force with joint training at NDA.

The CDS exam is perfect for graduates who want flexibility in choosing their service branch. Here’s why CDS might be right for you:

• Multiple Career Paths: Join the Army (IMA or OTA), Navy (INA), or Air Force (AFA) based on your qualifications and preferences.
• Eligibility: Open to graduates (degree requirements vary by academy). OTA allows both men and women for Short Service Commission (SSC).
• Exam Pattern: Includes English, General Knowledge, and Elementary Mathematics (except OTA, which skips Math). The GK section is UPSC-level, making it challenging but rewarding.

Best for: Aspirants seeking long-term commissions in the Army or Navy, or those who want multiple service options.

Why Choose AFCAT?

If your dream is to soar with the Indian Air Force, AFCAT is your go-to exam. Here’s what makes AFCAT unique:

• Air Force Focus: Offers roles in Flying (SSC only), Ground Duty (Technical/Non-Technical), and administration.
• Inclusivity: Open to both male and female candidates, with diverse academic backgrounds (graduation or engineering).
• Exam Pattern: Tests General Awareness, Verbal Ability, Numerical Ability, and Reasoning/Military Aptitude. The Engineering Knowledge Test (EKT) is required for Technical branches.

Best for: Candidates passionate about Air Force careers, especially women seeking SSC roles or those interested in technical positions.

Is NDA the Right Choice?

NDA is ideal for young aspirants ready to start their defence journey early. Key highlights include:

• Early Entry: For male candidates aged 16.5–19.5 years who have completed or are appearing for 10+2.
• Joint Training: Cadets train together at NDA before branching into IMA, INA, or AFA.
• Exam Pattern: Includes Mathematics (300 marks) and General Ability Test (600 marks, covering English, Physics, Chemistry, History, Geography, and Current Affairs).

Best for: Young students aiming to join the armed forces right after school.
