## Maths Chapter Wise Weightage in NDA Exam based on Previous Exams

 Maths Topics Number of Questions Weightage Differential calculus 24-26 Questions 20% Matrices and Determinants 8-10 Questions 6.66% Trigonometry 20-22 Questions 16.66% Statistics & Probability 10-12 Questions 8.33% Vector Algebra 8-10 Questions 6.66% Analytical geometry of two and three dimensions 18-20 Questions 15% Algebra 20-22 Questions 16.66%

## Why It is important to know the weightage of Maths Topics in NDA Exam

Maths Syllabus of NDA Exam is very vast and before starting preparation Candidates must know which topics they should focus more or which topics they should focus less. Candidates should prepare all the topics but they should focus more on those topics which have higher weightage in NDA Exam.
