The Union Public Service Commission (UPSC) conducts the National Defence Academy Exam popularly known as the NDA exam twice a year. The national level exam serves as a stepping stone for students interested in joining the Army, Navy, or Air Force. As the NDA exam approaches closer, many students who wish to clear it, in any case, become nervous. Many of us have nightmares about mathematics because it is not one of our strong suits.

To revisit the basics of the NDA Exam, the test has two papers i.e., Mathematics (300 marks)and General Ability Test (GAT) (600 marks). The questions will be of the objective type, and the candidates are granted two and a half hours to complete the exam.

Algebra, Matrices, and Determinants, Trigonometry, Analytical Geometry in Two and Three Dimensions, Differential Calculus, Integral Calculus, and Differential Equations, Vector Algebra, Statistics, and Probability will be covered in Paper 1. The mathematics paper is less weighted than the general ability test, but it is nevertheless important in shortlisting candidates.

On that note, let’s discuss a few last-minute preparation tips to boost your confidence in mathematics for the upcoming NDA exam.

NDA & NA Mathematics Preparation Tips

If you are familiar with the NCERT mathematics textbooks for classes 11 and 12, the mathematics subject is not difficult to master. Here are some helpful hints for passing paper I, which is mathematics.

  • For mathematics, the revision phase is critical. Spend at least three hours on the last day of your preparations going over the formulae.
  • Avoid confusion while converting decimal numbers to the binary system.
  • Trigonometry questions are relatively hard. Understand topics like triangle properties and inverse trigonometric functions.
  • The questions related to the analytical geometry of two and three dimensions consume a lot of time. Hence, keep this for the end and focus more on questions based on straight lines and circles. However, don’t sideline other topics like Ellipse, Hyperbola, Parabola and other concepts occasionally a question or two can be asked from them.
  • Although most of the concepts in differential calculus are vital, algebraic operations on continuous functions and derivative applications in maxima and minima issues are particularly crucial.
  • The most essential unit in the syllabus is vector algebra. Give the vector product or cross product of two vectors a cornerstone.
  • Once you’ve figured out the logic, the statistics chapter is simple, but be cautious when taking down the numbers. A single blunder may be costly for you.
  • The elementary theorems, Bayes’ theorem, and binomial distribution are significant in probability. Give yourself no more than two minutes to answer the questions.
  • The only way to achieve success in mathematics is to practise. During the last week, practise for at least two hours every day.
  • Do not start pursuing any topics in your final days. Practice the previous year’s papers and mock tests as much as possible.
  • Eat nutritious foods and get at least 8 hours of sleep to keep your mind active and focused.
  • Revise the short notes that you have made while the preparation. However, you can also refer to short notes available on the internet on any topic. For example, if you are having trouble finding Locus examples or theorems in two-dimensional geometry in books then the internet will come to your rescue.
  • As you are probably aware, there is a negative marking structure in the NDA Exam. As a result, try to avoid making educated predictions during the exam.
  • Make the most of your exam time. Prioritize the easier questions and avoid wasting time predicting solutions.
