# Important Tips to Prepare Mathematics for NDA & NA 2022 Exam

By Dhruv Kumar|Updated : December 23rd, 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 1 2022 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 1 2022 exam to give your preparation an edge over others!

## Important Strategy to Prepare Maths for NDA & NA 2022 Exam

First, let us 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

Below table mentions the topics that are asked & the number of questions asked topic wise.

## 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.

## FAQs

• 120 questions are asked that constitutes total of 300 Marks (Paper 1)

• Yes, .83 marks will be deducted on every wrong response

• Topics like Complex numbers, P&C, vectors & 3 D, Binomial theorem, trigonometry ratios & identities, coordinate geometry & calculus are high weightage topics.

• The candidate can refer to any of the under-mentioned books to aid in their preparation of the mathematics section of NDA exam:

1. R S Aggarwal: Mathematics for NDA and NA: National Defense Academy and Naval Academy

2. Arihant Study Package Mathematics NDA/NA Entrance Exam

3. Path Finder for NDA and NA National Defense Academy/Naval Academy Entrance Examination

4. NCERT Mathematics Textbook for Class XI & XII

• The level of questions that are asked is moderate. First of all make work on your subject & conceptual understanding & then start with practicing PYQs & some extra questions from the books that you have. In the end it all comes down to speed & accuracy, that is how fast you can apply your concept understanding & solve the questions. Always practice in time bound manner.
