Introduction
The NDA-I 2026 Exam, conducted by UPSC, is one of the most sought-after defence exams in India. Lakhs of candidates appear every year, but only a small percentage clear both the written exam and the SSB interview.
The difference between success and failure often comes down to avoiding common mistakes during preparation. In this article, we highlight the top mistakes NDA aspirants make, how to avoid them, and strategies to prepare smartly. We’ll also share how Victor Growth Coaching helps students stay disciplined, confident, and exam-ready.
Top Mistakes to Avoid in NDA-I 2026 Preparation
1. Ignoring the Exam Pattern and Syllabus
Many aspirants start preparation without clearly knowing the NDA syllabus.
NDA consists of Mathematics (300 marks) and GAT (600 marks), plus SSB Interview.
👉 Tip: Go through the official syllabus and UPSC pattern before starting. Create a checklist of topics.
2. Focusing Only on Mathematics
Maths is important, but GAT carries double the weightage (600 marks).
Ignoring English, Physics, Chemistry, Biology, History, and Current Affairs can cost selection.
👉 Tip: Allocate equal time to Maths and GAT. Practice English daily and stay updated on GK.
3. Lack of Time Management
Many students waste time on one subject or attempt too many guesswork questions.
This leads to negative marking and poor scores.
👉 Tip: Practice mock tests to learn time allocation and accuracy. Attempt easy questions first, then move to difficult ones.
4. Skipping Mock Tests and PYQs
Some aspirants only revise theory without solving Previous Year Question Papers (PYQs) or mock tests.
This results in exam-day panic due to unfamiliarity with question style.
👉 Tip: Solve at least 10–15 full-length NDA mock tests before the exam.
5. Overlooking English Vocabulary and Grammar
English accounts for 200 marks in GAT, yet many ignore it.
Poor grammar and weak vocabulary reduce chances of scoring.
👉 Tip: Learn 10–15 new words daily, revise grammar rules, and practice comprehension passages.
6. Not Revising Regularly
Studying without revision makes you forget important formulas and facts.
Last-minute cramming never works for NDA’s vast syllabus.
👉 Tip: Revise weekly. Maintain a formula sheet and GK flashcards.
7. Neglecting Current Affairs
Many aspirants skip newspapers and rely only on static GK.
UPSC frequently asks about defence news, international relations, and government policies.
👉 Tip: Read daily newspapers, and revise monthly current affairs magazines.
8. Avoiding Physical Fitness and SSB Preparation
NDA selection doesn’t end with the written exam. SSB Interview and medical fitness are equally crucial.
Ignoring fitness, confidence-building, and communication can lead to rejection.
👉 Tip: Start physical training early (running, pushups, endurance drills). Practice group discussions and mock interviews.
9. Depending Too Much on Guesswork
NDA has negative marking: –0.83 (Maths), –1.33 (GAT).
Random guessing reduces overall score.
👉 Tip: Attempt only questions you are reasonably sure about. Accuracy matters more than number of attempts.
10. Not Seeking Expert Guidance
Self-study helps, but without proper mentorship, many aspirants study in the wrong direction.
Lack of strategy and discipline lowers success chances.
👉 Tip: Join a reputed NDA coaching institute like Victor Growth for structured preparation, expert guidance, and mentorship.
