What is NDA Exam?

The National Defence Academy (NDA) exam is one of the most prestigious competitive tests in India, conducted by the Union Public Service Commission (UPSC) twice a year. It serves as the joint services academy entry point where selected cadets of the Army, Navy, and Air Force train together before going to their respective service academies.

Both male and female candidates can apply for the NDA written exam after passing or appearing in Class 12th. At Droneshwar Defence Academy (DrDA) in Dehradun, we combine comprehensive written coaching (specialized math focus by Sandeep Sir) with standard physical GTO ground workouts and retired colonel board assessments to help aspirants clear the written exam and SSB interview.

NDA Selection Process

  1. UPSC Written Exam: Consists of Mathematics (300 marks) and GAT (600 marks) papers held on the same day.
  2. 5-Day SSB Interview: Evaluates OIR, PPDT, psychological tests (TAT, WAT, SRT), Group Testing Officer (GTO) obstacle tasks, and Personal Interview.
  3. Medical Test & Merit: Detailed medical evaluations are conducted by a military board. Finally, the national merit list is prepared to induct selected candidates as cadets.

NDA Written Exam Pattern

The written exam is conducted offline using OMR sheets:

Paper Subject Area Number of Questions Maximum Marks Duration
Paper 1 Mathematics (Algebra, Trigonometry, Calculus, Probability, Vectors) 120 Questions 300 Marks 2.5 Hours
Paper 2 General Ability Test (GAT - English & General Knowledge) 150 Questions 600 Marks 2.5 Hours
Total Written Score 270 Questions 900 Marks 5 Hours

Physical & Medical Standards

Candidates must be in excellent physical and mental health to cope with the rigorous training at Khadakwasla. Major standards include:

  • Minimum Height (Boys): 157 cm (162.5 cm for the Air Force). Relaxations are provided for Gorkhas, Garhwalis, and Kumaonis.
  • Minimum Height (Girls): 152 cm (162.5 cm for the Air Force).
  • Eyesight limits: Army eyesight must be correctable to 6/6 with glasses. Air Force entry requires 6/6 in both eyes without corrective lenses.
  • Physical Fitness: Candidates should be able to run 2.4 km in 15 minutes, perform 20 squats, and do 10 push-ups.

Training, Salary & Career Growth

Selected cadets spend 3 years at the National Defence Academy (NDA) Khadakwasla, Pune, undergoing academic education alongside intense physical conditioning. Upon graduation, they receive a Bachelor's degree (BSc, BA, or BTech).

Post Khadakwasla, they undergo 1 year of pre-commission training at IMA Dehradun (Army), INA Ezhimala (Navy), or AFA Dundigal (Air Force). During this training year, cadets receive a stipend of Rs. 56,100 per month. Upon commission as a Lieutenant or Flying Officer, they receive full pay and allowances starting at Level 10 of the 7th Pay Commission pay scale.

NDA Preparation Strategy & Common Mistakes

To clear the UPSC NDA exam in your first attempt, follow these professional strategies:

1. Practice Maths Daily

UPSC NDA Paper 1 is the decider. If you do not score above the 25% sectional cutoff in Mathematics, your GAT paper will not be evaluated. Practice concepts and learn shortcuts for trigonometry and calculus.

2. Focus on English and Science

In GAT, English carries 200 marks, while Physics, Chemistry, and General Science carry 200 marks. These subjects have high scoring potential and can boost your overall written score.

Common Mistakes to Avoid

  • Ignoring the sectional math cutoff, thinking you can make up for it in GAT.
  • Over-attempting questions and losing marks to negative marking.
  • Neglecting spoken English and physical fitness until after the written exam results are out.
