The National Defence Academy(NDA) is an iconic istritution, a global brand of excellence in the sphere of military education. The final recommended may also choose Indian Naval Academy(INA) which provides specialized training to naval cadets

For recruitment to the Indian Army, Navy and Air force wings of Indian Army, there is prestigious NDA&NA Exam. To join NDA or NA a candidate must appear the entrance exam conudted by UPSC, twice a year.

## Exam Pattern

The exam is of 900 marks. There is a negative marking of one-third marks assigned to the questions. The exam is divided into two papers: 1. Matematics 2. General Ability Test

There are 120 mcq questions. Each item is of 2.5 marks and a wrong answer will fetch you a negative marking of 2.5/3=0.833 marks.

The syllabus is that of 11th and 12th classes. The questions asked are either easy or moderate in difficulty.

The General Ability Test is divided into two parts: 1. English and 2. General Knowledge. Each question in this paper is worth 4 marks and a negative marking of 1.33 marks

**Part A: English: **This portion is designed to test the candidate’s understanding of English.The syllabus covers various aspects like grammar and its usage, vocabulary and comprehension. There are 50 questions with a total of 200 marks. Questions include spotting errors, antonyms and synonyms, sentence improvement and completion, vocabulary etc. If you have a nice grip of English you will find this section easy and most scoring.

**Part B: General Knowledge: **This portion broadly covers the subjects Physics, Chemistry, General Science, Social Studies, Geography and Current Events. It contains 100 questions for a maximum of 400 marks
