Brief summary of NDA exam and NDA I 2017 Notification pdf

The National Defence Academy (NDA) and Naval Academy (NA) Exam is conducted by Union Public Service Commission UPSC.

Throughout this blog any reference to NDA would include NA unless otherwise specified.

From the time of issuance of notification till the starting of the course at NDA , the time taken is roughly one year.

Selection procedure involves a written test and SSB interview.

Both written test and SSB interview carry equal weightage of 900 marks.

Final merit list of candidates is prepared on the basis of total marks scored by candidates in written and SSB interview.

There is common misconception that final rank is decided solely on the basis of SSB interview. But notification clearly mentions that total of written and SSB interview is taken into consideration.

There is cut off for each subject ( i.e. each paper ) of written exam, overall written exam cut off and SSB interview cut off and finally total marks cut off.

The exam( both written and oral) is conducted twice a year.

The age of the candidate should be between 16 1/2 and 19 1/2 on the date of commencement of course and between 15 1/2 to 18 1/2 on the date of issuance of notification ( approx - exact dates given below) . As it takes approximately one year for the process to complete.

Education Qualification : For NDA 1 the candidate must be in class 12 and for NDA 2 the candidate must be Class 12 pass.

Medical Examination is not tough (requiring super human capabilities) but elaborate to ensure that candidate is healthy. Before starting preparation , a candidate is advised to read the medical requirements and get himself checked in case of doubt.

Some important statistics :

1. In NDA 1 2016 more than 5,00,000 student filled the form. ( last qualified roll no. was 503968 starting from 2 )

2. Out of these only 8363 student qualified in written test( Less than 1.7 % - JEE mains more than 20% )

3. Out of these only 447 were finally selected ( less than 0.1 % of students who filled the form and around 5% of student who qualified the written paper - compare this to success rate of more than 2 % in JEE advanced )

NDA 2017 Important Notification :

NDA 2017 Exam Pattern:

The time duration for NDA 2017 written exam is 5 hours for both papers, of which 2 hours and 30 minutes for each of the two papers. The written exam was of total 900 marks, where Maths paper was of 300 marks and General Ability for 600 marks.

Papers consisted of objective type questions and the question papers (Maths & General Ability) were set in both English and Hindi.

The exam was conducted in pen and paper mode.

One-Third mark was deducted for each wrong answer. In case a candidate marked more than one response for any question, it is treated as a wrong answer and negative marking was applied.
.
