NDA (I) & (II) Examination Pattern 2021

The National Defense Academy exam pattern is designed to assess a candidate’s academic experience and that candidate’s ability to present themselves in a systematic and consistent manner.

The test pattern aims to assess the general intellectual traits and the level of understanding of the candidates.

The 2020 Exam is a National Defense Academy conducted in two stages, namely Part I, Part II, which are then followed by an interview.

  • NDA and NA-I
  • NDA and NA-II
  • Interview/personality test

Points to remember: –

  • Papers in all subjects will consist only of objective questions.
  • The Mathematics Question Papers (Test Booklets) and Part ‘B’ of the General Ability Test will be set up bilingual (able to speak two languages fluently) in Hindi and English.
  • In the question documents, whenever necessary, only questions related to the metric system of Weights and measures will be established.
  • Candidates must write the documents in their own hands. In no case will the help of a scribe be allowed to write answers for them.
  • The Commission has the discretion to set grades for any or all of the subjects on the exam. Candidates cannot use the calculator or the mathematical or logarithmic table to answer objective type documents (test booklets). Therefore, they should not bring the same into the exam room.

  • Stage II Comprises of Interview, Group Testing Officer Tasks, Psychology Tests and the Conference.These tests are conducted over 4  The details of these tests are given on the website joinindianarmy.nic.in.

  • The personality of a candidate is assessed by three different assessors viz. The Interviewing Officer (IO), Group Testing Officer (GTO) and the Psychologist. There are no separate weightage for each test. The mks are allotted by assessors only after taking into consideration the performance of the candidate holistically in all the test. In addition, marks for Conference are also allotted based on the initial performance of the Candidate in the three technique and decision of the Board. All these have equal weightage.
  • The various tests of IO, GTO and Psych are designed to bring out the presence / absence of Officer Like Qualities and their trainability in a candidate. Accordingly candidates are Recommended or Not Recommended at the SSB.
