Complete Guide to NDA physics numerical practice 2026

To master NDA physics numericals, prioritize high-yield topics like Mechanics, Optics, and Current Electricity. We at Exam Bhai recommend solving at least 500+ past-year questions, focusing on unit conversion, dimensional analysis, and rapid mental calculation. Consistent practice with targeted NDA mock tests for Defence is the key to clearing the cutoff.

What is the Exam?

The National Defence Academy (NDA) examination, conducted by the Union Public Service Commission (UPSC), is the premier gateway for youth to join the Indian Armed Forces (Army, Navy, and Air Force). It is a rigorous selection process designed to test the mental agility, physical endurance, and academic strength of candidates. The physics section is a critical component of the General Ability Test (GAT), carrying significant weightage that can determine your overall merit rank.

Key Highlights 2026

• Conducting Body: Union Public Service Commission (UPSC)
• Exam Level: National
• Mode of Exam: Offline (Pen and Paper)
• Frequency: Twice a year (NDA I and NDA II)
• Total Physics Weightage: Physics typically contributes 20-25 questions in the GAT paper, each carrying 4 marks, totaling nearly 80-100 marks.
• Primary Focus: Application-based questions requiring a deep conceptual understanding.

Syllabus 2026

Physics in the NDA syllabus is vast, ranging from basic mechanics to modern physics. At Exam Bhai, we have analyzed the trends to categorize the topics.

Exam Pattern

The GAT paper is where your physics prowess is tested. It is crucial to understand the distribution to strategize your attempt effectively.

Candidates looking to optimize their performance should practice free physics numericals for Defence on Exam Bhai to get accustomed to the time constraints and negative marking scheme.

Eligibility Criteria

According to the official upsc.gov.in guidelines, candidates must meet the following criteria:

• Age Limit: Must be between 16.5 and 19.5 years as of the date of joining.
• Educational Qualification: For the Army wing, 10+2 pass; for Air Force and Navy wings, 10+2 pass with Physics, Chemistry, and Mathematics.
• Nationality: Citizen of India, subject of Nepal/Bhutan, or Tibetan refugee who came to India before Jan 1, 1962.

Application Process

1. Visit the official portal at upsc.gov.in.
2. Register using the One-Time Registration (OTR) system.
3. Fill out the application form with accurate personal and academic details.
4. Pay the requisite application fee (exempted for SC/ST/Sons of JCOs/NCOs/ORs).
5. Select your preferred examination center and submit the form.

Preparation Strategy

Physics numericals are not about rote memorization but about applying concepts. We at Exam Bhai suggest a three-step approach:

1. Conceptual Foundation: Don't skip NCERT. Physics in NDA is heavily grounded in NCERT concepts from class 9th to 12th.
2. Formula Sheet: Create a dedicated notebook for formulas, especially for Optics (mirror/lens formulas) and Electricity (Ohm's law, series/parallel combinations).
3. Active Testing: You must solve previous year physics papers for Defence on Exam Bhai. This helps in identifying recurring numerical patterns like velocity-time graphs or resistance calculations.

Cut-Off Trends

Cut-offs are determined by the UPSC and published on upsc.gov.in. Historically, the final written cut-off for the NDA exam fluctuates between 340 and 360 marks out of 900. Since Physics is a high-scoring section, securing a high score here acts as a buffer against the tougher sections of the GK paper.

Frequently Asked Questions

Q1: Are calculators allowed in the NDA exam? No, calculators are strictly prohibited. You must improve your mental math speed to handle physics numericals.

Q2: Which books are best for NDA physics numericals? NCERT Physics textbooks (9th-12th) are the gold standard. Additionally, Pathshala or Arihant publications are good for practice.

Q3: How many physics questions are numericals? Typically, 40-50% of the physics questions are numerical-based, while the rest are conceptual/theoretical.

Q4: Is the difficulty level similar to JEE Main? No, NDA physics is significantly easier than JEE Main. It focuses on conceptual clarity and basic application rather than complex integration or advanced calculus.

Q5: How to handle negative marking in physics? Focus on accuracy over quantity. If you are unsure about a complex numerical, it is better to skip it than to lose marks on a wrong guess.

Q6: Does the syllabus change every year? The core physics syllabus remains consistent as per UPSC guidelines, though the distribution of questions across chapters may vary slightly.
