NDA Exam 2020 (1& 2) was held on 6th Sep, 2020 and the Mathematics Paper of NDA 1 and 2 2020 consisting of 120 questions was of moderate level. Here is the complete breakdown of NDA 1 2020 and NDA 2 2020 Mathematics question paper.
The Components of NDA Mathematics Syllabus are:
- Algebra
- Matrices & Determinants
- Trigonometry
- Analytical Geometry 2D
- Analytical Geometry 3D
- Differential Calculus
- Integral Calculus
- Vector Algebra
- Statistics
- Probability
Here is the topic wise detail analysis of questions been part of this exam paper.
As there are 10 subtopics of this main topic Algebra, here we can see Micro analysis of this topic.
Going through topic wise analysis of questions we can deduce that the Trigonometry topic covered highest ever count, i.e. 25 questions out of 120 questions that’s approx. 22% of the paper, including most of the questions on Trigonometric Ratios varying between easy to moderate level of difficulty. And in comparison, with previous NDA 2 2019 paper, Algebra covered less part of the paper, it consisted of 25 questions which are minimum number of questions on Algebra as expected. This paper has easy to moderate level questions on Functions, complex numbers, Quadratic equations, Binomial expansions and Logarithms, etc. Commenting on Matrices and Determinants, the weightage was good, 8 questions which are higher than NDA 2 2019 paper. The Coordinate geometry/systems and Straight lines topics covered good number of questions out of 10 questions of Coordinate Geometry-2D. Paper maintained usual trend of 1-1 question each on Circle/Parabola/Ellipse.
Commenting on Analytical Geometry-3D, it has maintained equal number of questions on Line and Plane and 1 question on Sphere. Integral calculus and Differential Calculus followed approximately 22 questions together out of which good number of questions were on Limits, Derivatives, integral calculus and Differential equations. Level of these questions was easy to Moderate. Vector as usual covered approx. 4% of the question paper, i.e. 5 questions out of 120 which were as per the trends, demanding basic knowledge about this topic including all the subtopics. Statistics and Probability consisted of 20 questions altogether. Statistics required the conceptual knowledge about Central measures of tendencies and important formulas. Whereas the level of questions on this topic was average.

So, basically the students who have prepared well for Trigonometry, Algebra, Statistics & Probability, Differential Calculus, Integral Calculus, 2d geometry were in advantage. In particular, after analyzing this paper, we can conclude that NDA is expecting more knowledge about Trigonometry, Algebra, Calculus, Statistics& Probability. Here is the Overall topic wise analysis of NDA Mathematics 2020.
