NDA Syllabus 2021 April

National Defense Academy / Naval Academy entrance exam conducted twice a year by UPSC. There are two papers in the NDA Exam – Mathematics and General Aptitude Test. Paper 1 in NDA includes Mathematics. The Syllabus of the NDA exam is the same as last year. In the Exam Question, 10 + 2 level questions will only be asked. General Ability Test (GTA) is the 2nd paper of the NDA Exam, which is divided into two parts- English and General Knowledge. The GAT is meant to evaluate a Students’ basic awareness and English proficiency. Now check the Detailed Syllabus of the NDA exam 2021.
