The most significant element of CAT 2021 preparation, specifically for the Quantitative Aptitude portion, is remembering the formulae and theorems, because understanding such crucial formulas will allow you to know when and how to apply them. Since a result, it becomes even more critical for a candidate to be well-versed in fundamental formulae, as they will be asked to complete problems quickly and accurately.

Gain, Loss, and Discounts, Numerical System, Time and Work, LCM and HCF, Logarithm, Avg, Set theory & Functions, Probability, Permutation & Combination, Trig, Mensuration, Coordinate Geometry, and others are among the topics covered in the QA part. Formulae are an essential component in acing the quantitative section of the CAT Exam.
