Permutation and Combination Essentials for CAT Prep

Struggling to figure out when to multiply, when to add, or when to use a combination instead of a permutation? Mastering these counting principles is crucial for scoring high on the quantitative aptitude section of the CAT and other competitive exams. This text-based course breaks down complex combinatorial mathematics into logical, easy-to-digest concepts, helping you build a strong foundation without relying on rote memorization. You will learn to approach word problems systematically and identify the underlying mathematical structure of any arrangement or selection problem. By the end of this course, you will confidently solve diverse counting problems, from basic digit arrangements to complex grouping scenarios. What you will learn: Understand the fundamental counting principles of addition and multiplication; Master formulas for permutations, circular arrangements, and identical items; Apply combination formulas to selection, grouping, and distribution problems; Solve advanced CAT-level probability and grid path problems using systematic counting; Practice modern problem-solving strategies to avoid double-counting and common traps. The course begins with core definitions and basic counting rules before progressing to advanced selection strategies, grouping techniques, and exam-style practice questions. This course is designed for beginners starting their CAT preparation and any learner looking to build a rock-solid foundation in quantitative aptitude from scratch.
