"This section isn't just about getting into business school — it's about being ready once you're there."
Host GMAC Zach welcomes back GMAT expert Sergey Kouk from Admit Master for a deep dive into one of the most anxiety-inducing parts of the exam: the Data Insights section.
Together, Zach and Sergey demystify what Data Insights really tests, why it matters for business school and recruiting, and how test-takers should approach it strategically rather than emotionally. Sergey explains how the section builds on the former Integrated Reasoning questions, why Data Sufficiency now plays a central role, and how success depends far more on logic, structure, and decision-making than on heavy math.
The conversation walks through each Data Insights question type—Data Sufficiency, Graphics Interpretation, Table Analysis, Two-Part Analysis, and Multi-Source Reasoning—highlighting common pitfalls, practical tactics, and efficient workflows for each. Sergey emphasizes proactive thinking: identifying what information is needed before diving into the data, staying methodical under time pressure, and avoiding the temptation to brute-force calculations.
Listeners also learn how to manage time effectively, when (and when not) to use the calculator, and why guessing strategically and moving on can be smarter than getting stuck. Throughout the episode, Sergey draws clear parallels between Data Insights questions and real business scenarios, reinforcing why this section is so relevant for MBA readiness and post-MBA careers.
The episode wraps with actionable advice on reducing stress, using the review function wisely, and preparing for business school—not just the test. Whether you're intimidated by Data Insights or looking to refine your approach, this conversation offers clarity, confidence, and a roadmap for mastering the section.
