NDA Written Exam is conducted twice a year by UPSC (Union Public Service Commission). Around 4 lakh aspirants, every year, sit for the exam, and only 6 thousand get the call for the SSB interview. So, most of the defense aspirants search for the tips and tricks to crack NDA in first attempt!

Several aspirants clear the exam in their very first attempt, and several cannot do it in 3,4 attempts. One should always focus on the syllabus and exam pattern.

So this article contains some NDA tips and tricks, NDA Syllabus based on proper exam analysis.

**Note**: Before joining NDA, one should clear the exam and SSB interview. This article strictly focuses on the exam.

## About National Defense Academy (NDA)

Before you crack the exam, you should know what you are preparing for; NDA (National Defense Academy). NDA is a prestigious joint service defense training institute of Indian Armed Forces, where cadets of the Indian Army, Indian Navy, Indian Air force train before they go to their respective Academies like IMA, INA, AFA. NDA is situated in Khadakwasla, Pune.

You will be excited to know that the recent chief of all three services Army, Navy, Air force, all are NDA alumni.

## NDA Written Exam Pattern

Itâ€™s very crucial to understand exam patterns before appearing in. The paper consists of two parts.

**Mathematics**(Paper 1)- Max marks â€“300
- No. Of questions -120
- Negative Marking â€“ 0.83

**General Studies**(Paper 2)- Max marks â€“ 600
- No of questions â€“ 150
- Negative Marking -1.33
- Time â€“ 2.5 hours

NDA Written Exam tests your knowledge, patience level, and basics of your academics. Each paper is for 2.5 hours, and in between 1 hour 30-minute refreshment break is given.

**NOTE:** You have to clear both the paper cut-off individually and then the overall cut-off.

- For Mathematics, the cut-off nearly varies from 75 to 100 marks.
- For General studies, the cut-off varies from150 to 180 marks.

As you can see the two paper has different cut-off, so one should prepare strategically.

### General Ability Syllabus

The general ability section comprises of **two parts** which are mentioned below:

#### Part â€“ A

**English:** The English syllabus covers vocabulary, Grammar and usage, comprehension, and cohesion in extended text to test the candidateâ€™s proficiency in English..

#### Part â€“ B

**General Knowledge:** The question paper comprises of general knowledge and covers the subjects that include Physics (11 and 12 NCERT), Chemistry (11 and 12 NCERT), Social Studies (6 to 10 NCERT), General Science, Geography(6 to 10 NCERT), and Current Events.

As ,You have seen the Syllabus is so vast, to prepare one should need hard work and determination and also most important proper strategy.

## Tips and Tricks To Crack NDA in First Attempt

Now, here are some tips which most aspirants follow to crack the Exam.

- An individual should have a basic knowledge of Physics, Chemistry, and Biology; so you should go through the previous year’s question papers.
- For current Affairs, you can use platforms like
*YouTube**,*etc. On YouTube, you can see the channel like**Telegram**,**Study IQ, Wi-Fi Study**, etc. - For Mathematics, Clear the basics from NCERT books of 11 and 12, and then you can go for RS Aggarwal or the previous year paper (at least five years ).
- English can be deciding factor because you can see around 50 questions from English, so solved previous year paper, S.P. Bakshi, Arihant PathFinder.
- For History, Geography, Polity, If you complete with your other subject then take these subjects.
- One of the most important is Time Management, especially when you are solving a paper of mathematics and general studies do only that question which you know; do not go for a guess.
- Remember negative marking is there; Firstly solve those questions on which you are 100% sure.

These are some tricks and tips one should follow based on my experience, so best of luck to all.
