NDA & CDS Exam 13 September 2026: Last 7 Days Strategy, Important Topics & Exam-Day Tips

The NDA and CDS examinations are scheduled for 13 September 2026, and thousands of defence aspirants are now entering the most important phase of their preparation—the final 7 days before the examination.

At this stage, the objective is not to study everything from the beginning. The right approach is to revise strategically, strengthen high-scoring topics, practise mock tests, analyse mistakes and enter the examination hall with confidence.

Whether you are appearing for NDA 2 2026 or CDS 2 2026, these final days can make a significant difference to your performance.

In this article, The Original Tutors brings you a practical last-week strategy for NDA and CDS aspirants, including important topics, revision techniques, mock-test strategy and an exam-day checklist.

NDA & CDS Exam 13 September 2026: What Should You Do Now?

With only a few days remaining, avoid making major changes to your preparation strategy.

Your priority should be:

• Revision rather than learning completely new topics
• Previous-year questions
• Full-length mock tests
• Analysis of mistakes
• Formula revision
• Current affairs revision
• Important static GK topics
• English vocabulary and grammar revision
• Time-management practice
• Maintaining proper sleep and concentration

The final week is about converting your existing preparation into marks.

Do not measure your preparation by the number of hours you sit at your desk. Measure it by how accurately and confidently you can solve questions under examination conditions.

NDA Last 7 Days Preparation Strategy

The NDA written examination consists of:

Mathematics – 300 Marks

and

General Ability Test (GAT) – 600 Marks

The total written examination is 900 marks.

Your final-week preparation should therefore focus on maximising accuracy in both papers.

NDA Mathematics: Important Topics to Revise

Do not attempt to complete every mathematical topic in the final week.

Instead, revise the chapters you have already studied and regularly practise questions from high-frequency areas.

Priority Mathematics Topics

• Algebra
• Quadratic Equations
• Sets and Venn Diagrams
• Trigonometry
• Matrices and Determinants
• Sequence and Series
• Permutation and Combination
• Probability
• Coordinate Geometry
• Straight Lines
• Circles
• Differential Calculus
• Integral Calculus
• Statistics
• Vector Algebra
• Mensuration

Pay special attention to:

Formula → Concept → Previous-Year Questions → Timed Practice

Do not spend excessive time reading theory that you already know.

NDA GAT: Important Topics for Final Revision

GAT carries 600 marks, making it extremely important for your overall NDA score.

The major areas include:

• English
• Physics
• Chemistry
• General Science
• History
• Geography
• Current Affairs

Focus on important factual and conceptual areas:

• Physical Geography
• Indian Geography
• Rivers of India
• Mountains and passes
• Climate
• Soil
• Agriculture
• Minerals
• Industries
• Natural vegetation
• Important geographical locations
• Oceans and seas
• World geography basics

Use maps and short notes instead of repeatedly reading lengthy chapters.

NDA Current Affairs: Last-Minute Strategy

Do not try to memorise years of current affairs during the final week.

Instead, revise important recent events and defence-related developments.

Pay attention to:

• Defence exercises
• Military appointments
• Important awards
• Sports events
• Space missions
• National and international developments
• Important government initiatives
• Science and technology
• Important personalities

Create a one-page rapid revision sheet containing facts that you repeatedly forget.

NDA English: Quick Revision Strategy

English can become a strong scoring area with focused revision.

Revise:

• Spotting Errors
• Sentence Improvement
• Fill in the Blanks
• Synonyms
• Antonyms
• Idioms and Phrases
• Ordering of Sentences
• Reading Comprehension
• Vocabulary
• Parts of Speech
• Prepositions
• Articles
• Pronouns
• Subject-Verb Agreement
• Tenses

Do not simply memorise vocabulary.

Practise questions and understand why an option is correct.

CDS Last 7 Days Preparation Strategy

For CDS aspirants, the approach should be slightly different because the written examination varies according to the academy being targeted.

Candidates should revise the subjects applicable to their examination and focus heavily on English, General Knowledge and Elementary Mathematics where applicable.

The most important principle remains:

Do not start preparing from zero during the last week. Strengthen what you already know.

CDS English: High-Priority Topics

English is one of the most important areas for CDS preparation.

Revise:

• Spotting Errors
• Sentence Improvement
• Fill in the Blanks
• Synonyms
• Antonyms
• Idioms and Phrases
• Vocabulary
• Ordering of Sentences
• Reading Comprehension
• Grammar
• Prepositions
• Articles
• Tenses
• Subject-Verb Agreement
• Parts of Speech

Spend some time every day solving English questions under a time limit.

CDS General Knowledge: Important Areas

For the final week, revise both static GK and recent current affairs.

Focus Areas

History

• Ancient India
• Medieval India
• Modern India
• Freedom Movement

Polity

• Constitution
• Fundamental Rights
• Parliament
• President and Prime Minister
• Supreme Court

• Arithmetic
• Number System
• Percentage
• Profit and Loss
• Ratio and Proportion
• Time and Work
• Time, Speed and Distance
• Simple and Compound Interest
• Algebra
• Geometry
• Mensuration
• Trigonometry
• Statistics

The last week should focus on speed and accuracy rather than learning completely new concepts.

The Most Important Rule: Take Mock Tests

If you have studied but have not taken enough full-length mock tests, the final week is the time to correct that.

Ideally, attempt a mock test under conditions that resemble the actual examination.

After every mock test, divide your mistakes into four categories:

1. Conceptual Mistake

You did not understand the concept.

2. Silly Mistake

You knew the answer but made a calculation or reading error.

3. Time-Pressure Mistake

You knew the answer but could not solve it within the available time.

4. Guessing Mistake

You attempted a question without sufficient confidence.

This analysis is often more valuable than simply taking another mock test.

How Many Mock Tests Should You Take?

Do not chase a particular number.

The objective is quality analysis.

One properly analysed mock test can be more useful than several tests that you attempt without reviewing your mistakes.

After every test, ask yourself:

• Which topics are costing me marks?
• Which questions take too much time?
• Where am I making repeated mistakes?
• Am I attempting questions that I should leave?
• Is my accuracy improving?

Your goal should be to enter the examination with a clear attempt strategy.

What NOT to Study in the Last 7 Days

This is equally important.

Avoid:

❌ Starting completely new books

❌ Watching dozens of random strategy videos

❌ Changing your entire preparation method

❌ Trying to memorise thousands of new facts

❌ Spending the entire day on one difficult chapter

❌ Comparing your preparation with other students

❌ Taking mock tests without analysing them

❌ Studying late into the night and compromising sleep

Your final week should be about revision, practice and confidence.

NDA & CDS Final 7-Day Study Plan

A practical approach could look like this:

Day 7–6

• Full-length mock test
• Analyse mistakes
• Mathematics revision
• English revision
• Current affairs

Day 5

• GAT revision

Day 1

Keep the preparation light.

• Revise short notes
• Check examination documents
• Check examination centre details
• Prepare stationery and other permitted items
• Avoid a heavy study session
• Sleep properly

NDA & CDS Exam-Day Strategy

Your preparation does not end when you enter the examination centre.

Your performance on the day depends heavily on calmness and time management.

Before the Examination

• Reach the centre well in advance.
• Carry the required documents.
• Follow all examination instructions.
• Avoid unnecessary discussions with other candidates.
• Stay calm.

How to Attempt the Paper

Do not allow one difficult question to destroy your confidence.

If a question is taking too much time:

Leave it and move ahead.

You can return to it later if time permits.

Your objective is not to solve every question.

Your objective is to maximise your score with controlled accuracy.

Avoid Blind Guessing

NDA and CDS examinations use negative marking.

Therefore, random guessing can reduce your score.

Before marking an uncertain answer, evaluate:

• Do I know the concept?
• Can I eliminate options?
• Is there enough information to make an educated choice?

Make calculated decisions rather than emotional ones.

Final 24-Hour Strategy for NDA & CDS

The last 24 hours are not the time to panic.

Do a light revision of:

Mathematics

• Important formulas
• Short tricks
• Common mistakes

English

• Vocabulary
• Grammar rules
• Important question patterns

GAT/GK

• Current affairs
• Defence-related developments
• Important static GK
• History
• Geography
• Science

Then stop.

Your brain also needs rest to perform well.

NDA & CDS Exam-Day Checklist

Before leaving home, make sure you have checked everything required according to your examination instructions.

Checklist

☑ Admit card / required examination document

☑ Valid identification document, if required

☑ Required photographs/documents, if specified

☑ Permitted stationery/items

☑ Examination centre and reporting time

☑ Route to the examination centre

☑ Travel time

☑ Any instructions mentioned by the examination authority

Most importantly:

Read the official examination instructions carefully before the exam.

One Week Before NDA & CDS: The Mindset You Need

At this stage, stop asking:

“Have I studied enough?”

Instead ask:

“How effectively can I use what I have studied?”

Thousands of students will appear for the examination.

Some will know more than you.

Some will know less than you.

Your job is not to compete with what somebody else has studied.

Your job is to perform your best paper.

Stay calm.

Read questions carefully.

Manage your time.

Avoid unnecessary negative marking.

Trust your preparation.

Final Message to NDA & CDS Aspirants

The final week can feel stressful.

You may feel that there are still hundreds of topics left to revise.

That is normal.

But remember:

You do not need to know everything to perform well.

You need to know your strengths, protect your marks, manage your time and avoid unnecessary mistakes.

Revise what you already know.

Practise intelligently.

Analyse your mocks.

Sleep properly.

And walk into the examination centre with confidence.

Your preparation has brought you this far.

Now, it's time to execute.

Stay focused. Stay disciplined. Give your best.
