The NDA2 2023 Exam is going to take place on 3rd September. So, It will be better to start preparing for the NDA2 2023 Exam from now only. NDA Exam is one of the toughest exams in India. It requires extensive preparation and a prudent strategy for clearing the NDA Exam. To help Candidates to prepare for NDA2 2023, we are going to provide NDA2 Exam Syllabus and Exam Pattern.
The NDA (National Defence Academy) exam is a highly competitive entrance exam conducted by the Union Public Service Commission (UPSC) of India for candidates who wish to join the Indian Army, Navy, or Air Force as an officer. It is a twostage selection process that includes a written exam and an SSB (Service Selection Board) interview. The written exam consists of two papers, Mathematics and General Ability Test (GAT), and is conducted in offline mode. The Mathematics paper is 300 marks, while the GAT paper is 600 marks. The total duration of the written exam is 5 hours. The GAT paper includes topics like English, General Knowledge, Physics, Chemistry, Geography, History, and Current Affairs.
Candidates who qualify for the written exam are called for the SSB interview, which is a fiveday selection process. It includes various tests like Psychological Tests, Group Testing Officer’s Tasks, Interviews, and conferences.
