If you prefer short, bite sized video lessons that focus on one concept at a time, work through the concept wise modules below.

Counting Methods | GRE Quant

Counting methods help you determine the exact number of possible outcomes when several choices or conditions work together, forming the base for permutations and combinations. The video, part of our GRE prep course, explains counting through a clear and structured flow, shows how to break scenarios into logical steps, track choices carefully at every stage, and match the method to the way the problem is built. It then applies this thinking to GRE style questions so counting logic feels clear, efficient, and exciting to use while solving problems.

Basics of Permutations and Combinations | GRE Quant

Permutations count arrangements where order plays a role, while combinations count selections where order has no effect, together forming the backbone of structured counting. The video lesson explains how to choose between permutations and combinations with clarity, breaks down the reasoning behind each method, and shows how the decision depends on what the question truly asks. It then applies these ideas to GRE style questions so ordered and unordered counting feels clear, efficient, and easy to apply.

How Permutation and Combination are Inter-Related | GRE Quant

Permutations and combinations describe the same act of choosing items, with the difference shaped by whether order plays a role or stays irrelevant. The flesson explains this connection in a clear and intuitive flow, showing how adding order turns combinations into permutations and how removing order shifts permutations back into combinations. It builds a strong mental bridge between the two ideas and shows why this relationship matters when solving counting problems.

An Explanatory Permutations Questions Set | GRE Quant

This solved question set starts with one core situation and explores it through eight thoughtfully crafted variations, where the base context remains the same while constraints shift in each version. These changes encourage you to view permutations from multiple perspectives and build flexibility in responding to evolving conditions. The video lesson walks through every variation in a clear sequence, shows how the logic adjusts as constraints change, and highlights the insights that emerge from comparing results. It helps you see how one idea expands into powerful problem solving and strengthens your grasp of permutation logic through structured and engaging practice.

An Explanatory Combinations Questions Set | GRE Quant

This practice set takes one combinations scenario and reshapes it into eight smart variations. The base situation stays the same, while the selection rules shift in each version. These changes show how combinations react to new conditions and how the final counts update with every added constraint. The experiential video lesson explains each variation in a clear, step by step flow and brings out the patterns that connect the full set. You build a strong feel for combinations as one idea becomes sharper through multiple structured angles.

Circular Arrangements | GRE Quant

This video explains circular arrangements in a clear and structured way. You learn how arranging items in a circle changes counting rules and why fixing a reference point matters. The lesson highlights how typical conditions influence valid outcomes. You then see how these circular arrangement ideas show up in real GRE questions.

Logic-Based Combinations | GRE Quant

Logic driven combinations highlight counting through clear reasoning instead of direct formula use. You solve these questions by spotting valid cases, arranging possibilities in an organized flow, and counting outcomes with sharp logic. The video lesson explains this method using varied situations, shows how to build cases step by step, and reveals how logical thinking leads to the final count. You then see the same approach applied to GRE style questions, which helps you handle logic driven combinations with clarity and strong control.
