The NDA Examination is conducted twice a year by the Union Public Service Commission to recruit candidates in Army, Navy, and Air Force. NDA Written exam consists of two papers: Mathematics and GAT. Mathematics Section in NDA exam includes 120 questions and a total of 300 marks with 2.5 marks being awarded for each correct answer and 0.83 marks deducted for each incorrect one. The paper duration is of 2 and half hours.View NDA study plan below
