What is NDA Exam Syllabus?

NDA exam syllabus is divided into two sections –

Math
General Aptitude

The General Ability section is divided into two parts – English and General Knowledge. The mathematics question paper will be of 12th standard.
Questions in Mathematics – Trigonometry, algebra, differential calculus, vector algebra, integral mathematics, etc. will be asked.

Questions in English – Grammar, vocabulary, comprehension, use in broad text and consistency, etc. will be asked to test the candidate’s proficiency.

Question paper in General Knowledge – will cover many topics like PhysicsChemistrySocial StudiesGeneral Science, GeographyCurrent Affairs, etc. The answers given by the candidates will show their intelligent understanding and knowledge of the subject.
