You will have to identify the pattern in order to get a 100% accurate answer. The pattern can be like anything- prime numbers, cubes/squares, cube roots/square roots, alternate numbers, difference, geometric series, etc. Make sure you solve at least 300-350 questions on different patterns of number series before appearing for the exam.

  • Arithmetic topics

Topics such as Interest, Percentage, Profit & Loss, Ratio and Proportion, Time and Work, Time, Speed and Distance, and Average, Mixture and Alligation are easy to prepare, less time-consuming, and have a low level of complexity. You can refer to previous years’ question papers for reference.

  • Quadratic Equations

Quadratic equations take time and record a low level of accuracy among students. So, you need to practise as many problems as you can. If your forte is not algebraic equations, then leave these questions for good.

  • Data Interpretation

8-10 questions are based on Data Interpretation (D.I.). Most of these questions come from bar graphs and pie charts. D.I. questions contain too much data and figures, so it is important that you focus on one question at a time. Practice various types of D.I. questions to improve your accuracy and speed. Avoid using a calculator while solving the paper.
