Recently Union Public Service Commission (UPSC) released notification for the beginning of Online Application for NDA 2018. Conducted twice a year, this entrance examination is a gateway to India's defence forces – Army, Navy and Air Force. NDA 2018 exam is scheduled to take place on April 22, 2018 and the last date to apply is February 5, 2018 till 6.00 pm. Since, this is one of the most sought after entrance examination, a thorough knowledge of Syllabus is critical for the success of students. NDA 2018 examination will have two papers. Paper–I is of Mathematics, having 300 marks and Paper–II is of General Ability Test, having 600 marks. Both these papers will be followed by an interview of 900 marks. Here's full NDA 2018 Syllabus with complete subject wise details.
