NDA 2 2025: Important Topics to Revise Before September 14

NDA 2 2025 countdown has started, and as the written exam is on September 14, the more time spent preparing, the better. The National Defence Academy exam is not only academic but also tests speed, accuracy, logical ability, and your capability of working under pressure.

This is not the time to do something new. Rather, it is a matter of reviewing high-scoring subjects and reinforcing areas that can provide you with the advantage. No matter how long you have been working on it or how you have just begun revising, the best strategy is a focused one.

Now is the time to put it all together if you have been using NDA books, doing practice sets out of an NDA previous year solved paper book, practicing grammar with an English book on NDA, or ensuring that your current affairs are up to date with a GK book on NDA.

What makes this Revision Phase so Important?

Revision before the NDA exam is not re-reading all the chapters. It’s about:

• Optimizing precision in the most tested subjects.

• Reduction of stupid errors in basic questions.

• Increasing speed by memorization of formulas and use of shortcuts.

• Working on areas you are weak in, which may result in a loss of marks.

It is equivalent to playing a match without taking penalty shots in practice; you may be good, but without the practice, performance will decline.

Which maths topics should I focus on most for NDA 2 2025?

Mathematics is a make-or-break section. In NDA 2, some of the topics are almost recurrent and predictable annually. These include:

• Algebra: quadratic equations, sequences and series, complex numbers.

• Trigonometry: heights and distances, trigonometric identities, equations.

• Coordinate Geometry: Straight lines, circles, conic sections.

• Probability and Statistics: Mean, median, mode, simple probability.

Revise formulae every day -if you are using NDA books, have a page where you can quickly look up formulae.

How should I revise English for NDA 2 in the last month?

In the GAT paper of NDA, English is scored directly. Focus on:

Grammar: Agreement of subject and verb, tenses, use of prepositions, active and passive voice.

• Vocabulary: Synonyms, antonyms, one-word substitutes.

• Comprehension: Train fast reading and search for answers in the text.

• Error Spotting: This is normally simple but needs a good grammar background.

Now you should use your English book when preparing for the NDA as your quick-revision one - no theory reading, only practice.

How important is GK in NDA 2 2025?

Extremely. GK includes both the static (History, Geography, Science) and dynamic (Current Affairs) topics.

• Static GK: Freedom struggle in India, physical geography, elementary physics & chemistry.

• Current Affairs: Sports, Government schemes, international relations, defence news.

In case you have a book on GK for NDA, use it to refresh the important facts and data points. Add to this the reading of newspapers or monthly current affairs PDFs.

Is solving the NDA previous year papers helpful?

Yes, and not just for question familiarity. Using an NDA previous year solved paper book helps in:

• Identifying frequently repeated questions.

• Understanding exam difficulty level.

• Practicing time management.

• Reducing anxiety on exam day because you’ve “seen it before.”

Aim to solve at least the last 10 years’ papers under timed conditions.

What’s the best strategy for the last week before NDA 2 2025?

Last week is not for new learning — it’s for consolidation.

• Day 1-3: Revise maths formulae, practice mixed question sets.

• Day 4-5: Focus on English and GK revision.

• Day 6-7: Take at least 2 full-length mock tests in exact exam timing.

Remember to analyze your mistakes in these mock tests to avoid repeating them.

Tips for Each Subject in the Last Month

Mathematics

• Create a formula chart and revise it twice daily.

• Practice past year questions for each topic.

• Focus more on problem-solving speed.

English

• Practice 20–30 grammar questions daily.

• Read 1–2 comprehension passages every day to build speed.

• Revise vocabulary lists in your English book for NDA.

General Knowledge

• Read 2–3 pages of your GK book for NDA daily.

• Watch a 5-minute news recap for current events.

• Revise static topics like the Indian Constitution, important dates, and geography maps.

How to Balance All Three Sections Effectively?

In the last month:

• 40% of your time → Mathematics (highest marks weightage in Paper 1).

• 35% of your time → GK (largest section in GAT).

• 25% of your time → English (easier to score but requires precision).

The key is to keep rotating subjects so none of them go untouched for more than 48 hours.

Mental Preparation & Exam Day Readiness

Revision isn’t just academic; mental readiness is equally important:

• Practice OMR filling while taking mock tests.

• Build the habit of skipping difficult questions and returning later.

• Sleep 7–8 hours before exam day.

• Keep your admit card, ID proof, and stationery ready a day before.
