**UPSC NDA NA Selection Process Details: **

Candidates who have done 12th (10+2) examination with Physics, Chemistry and Maths are able to apply online for the UPSC NDA (National Defence Academy) examination 2018. NDA selection procedure is based on the two process, first is Written examination and second is SSB Interview. Below we have given UPSC NDA selection process with brief information and required details.

**NDA Selection Process:**

UPSC conducts National Defence Academy (NDA) Examination in 2 Stages.

**Written Exam****Interview**

**Written Exam: **The written examination will consist in two papers – Mathematics and General Ability Test (English and GK). The Mathematics paper consists 120 questions, conducts for 2 ½ Hours and Maths paper consists maximum 300 marks. The General Ability consists 120 questions, conducts for 2 ½ Hours and General Ability paper consists maximum 600 marks. Both papers in all the subjects will consist of Multiple choice questions only. The Mathematics & Part B of General Ability Test question papers will be set bilingually in English and Hindi.

**Interview:** Students who will pass in the written examination will be called for Interview which is conducted by Services selection board (SSB). For the Indian Army, Indian Navy Wings and 10 +2 Entry Scheme students need to face Intelligence exam and Personality exam. However, for the Indian Air Force wing the students must have to attend a Pilot Aptitude exam. Therefore, the Interview consists both Intelligence and Personality exam.

**Intelligence and Personality Test:**

The SSB process consists of 2 stage selection procedure – stage 1st and stage 2nd. However, Only those students are permitted to appear for stage 2nd who clear the stage 1st. Full details are given below:

**Stage 1st:** This stage includes of OIR (Officer Intelligence Rating) exams are (PP and DT) Picture Perception Description Test. So, candidates will be shortlisted on the basis of combination of performance in the QIR Test as well as PP and DT.

**Stage 2nd: **This stage comprises of the Interview, Psychology Tests, Group Testing Officer Tasks as well as the Conference. In addition to, these stage 2 exams are held over 4 days.

The singularity of a candidate is judged by 3 different assessors namely – The IOI (Interviewing Officer), GTO (Group Testing Officer) as well as the Psychologist. In addition to, there are no separate consequence for each exam. All the marks are allotted by the assessors only after taking into opinion the candidate’s performance holistically in all exam / test. Along with, all marks for conference are also allocated in the basis of preparatory candidate’s performance in the 3 decision as well as techniques of the Board and all these have similar weightage.

As well as, the several tests of Interviewing Officer, Group Testing Officer, and Psychologist are designed to bring out the presence or absence of Officer such as qualities and ability in the candidate. By the way, students are Recommended or Not Recommended at the Services selection board (SSB).
