NDA Syllabus: NDA Syllabus & Exam Pattern

UPSC NDA Syllabus 2020 has been discussed here. The Union Public Service Commission (UPSC) conducts the National Defence Academy (NDA) Exam. NDA is a national level exam which is conducted twice a year. It is held for the candidates who want to join the Indian Defence Forces of India. This is one of the most sought after defence jobs in India to join the Defence of India as an Officer by the male candidates.

NDA Syllabus 2020: NDA Exam Pattern

Before getting into the NDA Syllabus let us have a look at the NDA Exam Pattern. The NDA Exam Pattern is different from that of the CDS Exam, which is also conducted by the UPSC for selecting meritorious candidates into the Defence Forces of India.  Check out the table for the exam pattern that is given below.

Subject Duration Maximum Marks
Mathematics 2½ Hours 300
General Ability Test 2½ Hours 600
Total 900
SSB Test/Interview 900

NDA Syllabus 2020: Marking Scheme

  • The Mathematics & General Ability Test will consist of objective type questions only.
  • There are four alternatives for the answer to every question.
  • One third (0.33) of the marks assigned to that question will be deducted as penalty for every wrong answer marked by the candidate.
  • If a candidate gives more than one answer for a question, it will be treated as a wrong answer even if one of the given answers happens to be correct and there will be the same penalty (0.33 marks) as above for that question.
