For any student with the dream to serve the Armed Forces of India, the NDA is the foremost thought. The National Defence Academy (NDA) is the Joint Services academy of the Indian Armed Forces. Thus the cadets of the three services, the Army, the Navy and the Air Force train together here before they go on to pre-commissioning training in their respective service academies. Hence Exammag brings you the all you need to know about NDA exam including NDA 2017 Exam Pattern and its syllabus.
The N.D.A. (National Defense Academy) exam is held twice in a year. It is conducted by U.P.S.C. (Union Public School Commission).
NDA 2017 Exam Pattern: Marking Scheme
The admission to NDA is conducted in 2 phases- Written Exam and SSB Interview.
First of all lets look at the Written Exam. As of now there will be no changes in the NDA 2017 Exam Pattern.
- As usual there will be 2 papers in N.D.A (National Defense academy) written exam. One is Mathematics and the other is General Ability. The questions will be in objective form.
- The time duration of each paper is 2½ hours.
- Furthermore, there is negative marking of 1/3rd of the marks allotted for a question. So you loose 0.33 for a wrong answer for a question of 1 mark.
|Subject||No. of Questions||Marks|
|General Ability Test||150||600|
Now, once you clear the cut-offs set by UPSC for the written exam, you would be invited for the next phase i.e. the SSB Interview. The SSB procedure consists of a two-stage Selection process-stage I and stage II. Only those candidates who clear the stage I are permitted to appear for stage II. The details are :-
(a) Firstly Stage I comprises of Officer Intelligence Rating (OIR) tests are Picture Perception & Description Test (PP&DT). The candidates will be shortlisted based on combination of performance in QIR Test and PP and DT.
(b) Secondly comes Stage II which comprises of Interview, Group Testing Officer Tasks, Psychology Tests and the Conference. These tests are conducted over 4 days. In addition to this you can find more details of these tests at www.joinindianarmy.nic.in.
The personality of a candidate is assessed by three different assessors namey- the Interviewing Officer (IO), Group Testing Officer (GTO) and the Psychologist. There is no separate weightage for each test. The marks are allotted by assessors only after taking into consideration the performance of the candidate holistically in all the tests. In addition, marks for Conference are also allotted based on the initial performance of the Candidate in the three techniques 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.
