Permutations and Combinations for GRE Math Prep

Counting problems on the GRE can often feel confusing, but mastering a few core mathematical rules can dramatically increase your quantitative score. This text-only course is designed to demystify combinatorics, helping you recognize exactly which formula to apply to any word problem. You will learn to break down complex scenarios systematically without relying on memorization traps. Through clear written explanations, you will build a strong foundation in counting theory and learn to approach even the most challenging GRE questions with a structured, step-by-step methodology.\n\nWhat you'll learn:\n- Understand the fundamental counting principle and when to add versus multiply.\n- Distinguish clearly between permutations where order matters and combinations where it does not.\n- Solve restricted permutation and combination problems involving specific grouping constraints.\n- Master the logic behind circular arrangements and how they differ from linear layouts.\n- Apply tactical written methods to identify and eliminate common traps like overcounting.\n- Practice with realistic GRE-style written scenarios and detailed step-by-step solutions.\n\nThis course begins with essential terminology and basic counting rules before advancing to complex restrictions and circular permutations. Each concept is reinforced with clear written breakdowns and practical exercises. Designed for GRE candidates of all mathematical backgrounds, this course requires no advanced prior knowledge.
