By Gagan Makkar|Updated : August 11th, 2021

NDA exam is a multiple-choice question-based exam broadly divided into 2 parts: Mathematics and General Ability Test. The overall paper is of 900 marks, out of which, Mathematics section accounts for 300 marks. Hence, scoring well in the Maths section is very crucial for clearing the written exam cutoff. Maths section can be scoring if the students are thorough with the concepts of this section, one can solve all the questions with 100% accuracy and there is a little scope of errors.

Here are some important tips on how to prepare the mathematics section for NDA & NA 2 2021 Exam. The NDA Mathematics preparation tips shared below also cover the estimated number of questions that might be asked from different sub-sections as well as the strategy to prepare them. So, read these tips to prepare for the Maths section of the NDA 2 2021 exam to give your preparation an edge over others!

Mathematics Preparation Tips for NDA Exam

  • The candidates must have a clear understanding of the syllabus & should note important and scoring topics based on the analysis of previous year papers. 
  • The candidates should make a proper time table allotting more time to important & high weightage topics.
  • The candidates should solve online mock papers to get the real feel of examination & get habitual with time bounded practice. It will develop the ability to solve maximum questions in limited time. Also solve previous year questions chapter wise to get the understanding of level of questions that are asked.
  • The candidates should learn shortcut tricks that can come handy during the exam time. You can refer to You Tube videos for that.
  • The candidates should remember fast calculation techniques for finding squares & cubes.
  • Make a important formula & shortcuts notes for quick revision.
  • The candidates should focus on developing the 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 NDA Mathematics section

  1. Algebra - Questions that are asked from 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, P&C.
  2. Calculus - It has important chapters like Application of derivatives, differentiation, definite integral, Area under the curve etc. If you develop good understanding of graphs & how to use them, you can score good marks in this section
  3. Coordinate Geometry - This is most scoring topics in NDA. This is another topic that can help you to acquire maximum marks.

Give more importance to chapters like Vectors, complex number 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 NDA Maths section. We will be posting more such article, stay tuned.
