The best NDA physics numerical practice course online provides structured, topic-wise problem sets specifically mapped to the UPSC syllabus. By focusing on conceptual application and high-frequency numerical patterns, students significantly improve their speed and accuracy in the General Ability Test (GAT), ultimately maximizing their marks for the 2026 examination.
What is the Exam?
The National Defence Academy (NDA) examination is one of the most prestigious competitive exams in India, conducted biannually by the Union Public Service Commission (UPSC). It serves as the gateway for induction into the Army, Navy, and Air Force wings of the NDA. The exam assesses a candidate's aptitude through a Written Examination followed by a rigorous Services Selection Board (SSB) interview process. Physics forms a substantial part of the General Science section, and mastering numerical problems is essential for securing a top rank.
Key Highlights 2026
- Exam Conducting Body: UPSC (Union Public Service Commission)
- Exam Frequency: Twice a year (NDA I and NDA II)
- Selection Stages: Written Exam and SSB Interview
- Exam Mode: Offline (Pen and Paper based)
- Language: Bilingual (English and Hindi)
- Physics Weightage: Approx. 20-25 questions in the GAT paper

Exam Pattern
The GAT paper, which includes Physics, is a crucial component for merit calculation. Understanding the distribution of marks is vital for your practice free mock tests for Defence on Exam Bhai.
| Paper | Subject | Questions | Marks | Duration |
|---|---|---|---|---|
| Paper II | General Ability Test (GAT) | 150 | 600 | 2.5 Hours |
| Physics | Part of GAT Section A | ~20-25 | ~80-100 | - |
Eligibility Criteria
According to the official upsc.gov.in guidelines, candidates must meet specific requirements:
- Age Limit: Must be between 16.5 and 19.5 years at the time of commencement of the course.
- Educational Qualification: 12th Class pass (10+2 pattern) with Physics and Mathematics for Air Force/Navy wings. For Army, 12th pass in any stream is acceptable.
- Nationality: Indian citizen, subject of Nepal/Bhutan, or Tibetan refugee settled in India since Jan 1962.
Application Process
- Notification: UPSC releases the official notification on the website upsc.gov.in.
- Registration: Candidates must fill out Part I and Part II of the online application form.
- Fee Payment: Pay the required examination fee through net banking or credit/debit cards.
- Center Selection: Choose an appropriate exam center from the list provided in the official notification.
- Admit Card: Download the hall ticket from the portal a few weeks before the exam date.
Preparation Strategy
Mastering physics requires more than rote memorization; it requires active application. We at Exam Bhai emphasize a three-step strategy to handle numericals effectively:
- Conceptual Foundations: Start by mastering basic formulas. For example, understanding the work-energy theorem $W = \Delta K$ is useless if you cannot apply it to incline plane problems.
- Structured Practice: Enroll in our NDA physics numerical practice course online to get access to over 500+ curated problems.
- Test Environment Simulation: Take regular assessments to build speed. You can start with our structured mock exams for UPSC Defence aspirants to identify your weak spots.
Remember to practice questions involving units and dimensions conversion, as this is a frequent trap in UPSC papers.
Cut-Off Trends
Cut-offs are determined by the UPSC and are published on upsc.gov.in. Historically, the total written exam cut-off for the NDA fluctuates between 340 and 360 marks out of 900. While there is no sectional cut-off for Physics specifically, scoring high here reduces the burden on other subjects like History and Geography, which are more subjective.
Frequently Asked Questions
Q1: How many numericals are usually asked in NDA Physics? A1: Generally, 20-25 questions are asked in the Physics section, with approximately 30-40% of these being numerical-based or conceptual application questions.
Q2: Is NCERT enough for NDA Physics? A2: Yes, NCERT books (Class 9-12) are the primary source for theory. However, for numerical practice, you need a specialized NDA physics numerical practice course online that provides exam-level problem sets.
Q3: Does Physics have negative marking? A3: Yes, there is a penalty of 1/3rd of the marks assigned to a question for every incorrect answer in the GAT paper.
Q4: Which topics are most important for numericals? A4: Mechanics, Optics (Lens/Mirror formula), and Current Electricity are high-priority areas where most numericals are centered.
Q5: Can I clear the exam without studying Physics? A5: While technically possible, it is not recommended. Physics contributes significantly to the GAT score; ignoring it makes qualifying for the merit list extremely difficult.
Q6: What is the best way to handle complex derivations in the exam? A6: NDA is an objective exam. Focus on remembering the final result and the conditions under which a formula applies rather than memorizing complex derivations.
