Important Strategy to Prepare Maths for NDA 1 2023 Exam
Before discussing the NDA maths preparation strategy, let us first talk about the pattern of the Mathematics section.
- Total duration: 2 ½ hours
- Total Number of Questions: 120
- Marks for each correct answer: +2.5
- Marks for each wrong answer: -0.83
- Maximum marks: 300
The table below mentions the topics that are asked & the number of questions asked topic-wise in the NDA Mathematics paper.

NDA Mathematics Preparation Tips
Look at the tips to prepare for the NDA Mathematics paper in the best manner:
- The candidates must have a clear understanding of the NDA syllabus & should note important and the scoring topics based on the analysis of NDA previous year papers.
- They should make a proper timetable allotting more time to important & high-weightage topics.
- They should solve NDA mock tests as many as possible to get the real feel of the examination & get habitual with time-bounded practice. It will develop the ability to solve maximum questions in a limited time. Also, solve previous year's questions chapter-wise to get an understanding of the level of questions that are asked.
- They should learn shortcut tricks that can come in handy during exam time. You can refer to our YouTube videos for that.
- The candidates should remember fast calculation techniques for finding squares & cubes.
- Make an important formula & shortcuts notes for quick revision.
- The candidates should focus on developing accuracy while solving the problems in time bound manner. One wrong question can keep you out of the race.
Here are the details of important topics for the NDA Maths section:
- Algebra - Questions that are asked in this section are usually easy. Most questions are formula & result oriented. So make sure you remember all the important results of complex numbers (cube root of unity, conjugate, etc), Binomial theorem, and P&C.
- Calculus - It has important chapters like Application of derivatives, differentiation, definite integral, Area under the curve etc. If you develop a good understanding of graphs & how to use them, you can score good marks in this section.
- Coordinate Geometry - This is the most scoring topic in the NDA Maths paper. This is another topic that can help you to acquire maximum marks.
Give more importance to chapters like Vectors, complex numbers and 3-D as compared to Probability or Indefinite integration. Most of the questions asked are result based. so make sure you maintain notes of all important formulas & results.
Hoping this article will help you in framing a winner strategy for the NDA Maths section. We will be posting more such articles, stay tuned.
