GMAT Data Insights is one of the most important sections for students targeting competitive MBA and business master’s programs. It measures how efficiently you can analyse charts, tables, text, numbers, and reasoning sets under strict timing. Many students understand the concepts but lose marks because they spend too long reading data, overcalculate simple information, or fail to decide when to move forward.
At Global Course, GMAT preparation focuses on accuracy, timing discipline, and business-style decision-making. For 2026 test-takers, Data Insights requires a clear strategy because every question type demands a different reading, filtering, and solving method.
Understanding the GMAT Data Insights Section
The Data Insights section includes 20 questions to be completed in 45 minutes. This means students have slightly more than two minutes per question on average. However, not every question deserves the same time. Some questions can be solved quickly through elimination, while others require careful reading of multiple sources.
The section may include Data Sufficiency, Multi-Source Reasoning, Table Analysis, Graphics Interpretation, and Two-Part Analysis. These question types combine quantitative reasoning, verbal reasoning, data interpretation, and logical judgement. The key is not only solving correctly but solving efficiently.
Why Timing Is Difficult in Data Insights
Data Insights timing is challenging because students must first understand the data before solving. In Quant, the question may directly show the calculation required. In Data Insights, the real task may be hidden inside a chart, table, condition, or paragraph.
Students often lose time by reading every detail before knowing what the question asks. A better method is to read the question task first, then examine only the relevant data. This prevents unnecessary scanning and reduces mental fatigue.
Start Every Question with the Task
The first timing rule is simple: identify the task before studying the data. Ask what the question wants. Is it asking for a trend, comparison, sufficient information, missing value, conclusion, relationship, or decision?
Once the task is clear, the data becomes easier to manage. You do not need to understand every number in a table if the question asks only for one condition. You do not need to study every label in a chart if the question asks for one comparison. This approach saves valuable minutes across the section.
Use a Two-Pass Timing Strategy
A two-pass approach works well for Data Insights. In the first pass, solve questions that are direct, manageable, and clear. Mark questions that are long, confusing, or calculation-heavy. In the second pass, return to the marked questions with remaining time.
This strategy prevents one difficult question from damaging the entire section. Students preparing through GMAT online coaching at Global Course practise this method during timed drills so they can make faster decisions under pressure.
Manage Data Sufficiency Efficiently
Data Sufficiency questions test whether the given information is enough to answer the question. Students should remember that they do not always need to calculate the final answer. The goal is to decide sufficiency.
First, understand the question stem. Then test each statement separately before combining them. Avoid using hidden assumptions. If a statement allows more than one possible answer, it may not be sufficient. This disciplined method saves time and reduces overcalculation.
Handle Table Analysis with Sorting Logic
Table Analysis questions can look overwhelming because of multiple rows, columns, and filters. Do not read the full table from top to bottom. First identify the column needed. Then sort or compare only the relevant values.
For true-or-false style items, evaluate each statement independently. Mark conditions carefully. If the question refers to percentage change, rank, average, minimum, maximum, or category comparison, go directly to those columns. Efficient table handling can save several minutes in the section.
Approach Graphics Interpretation Visually
Graphics Interpretation questions require students to understand charts, graphs, and visual data. Before calculating, read the axis labels, units, legend, and scale. Many mistakes happen because students misread units or compare the wrong categories.
Look for trends first. Is the value increasing, decreasing, stable, or fluctuating? Then check the exact question. Some graph questions can be answered through estimation, while others require precise calculation. Do not calculate when visual comparison is enough.
Control Multi-Source Reasoning Time
Multi-Source Reasoning can consume time because information appears across tabs, text, tables, or multiple references. The best strategy is to read the question first, then open only the source needed. Do not try to memorize all sources at once.
Create a quick mental map of each source. For example, one tab may contain background information, another may contain numbers, and another may contain conditions. Once you know where information is located, answering becomes faster.
Two-Part Analysis: Solve for Relationship
Two-Part Analysis questions test relationships between two decisions, values, categories, or conditions. Students often lose time because they treat each column separately. Instead, identify how the two parts are connected.
Ask whether the question requires matching, trade-off analysis, simultaneous equations, logical pairing, or comparison. Eliminate impossible combinations first. This reduces the number of options and makes the final selection easier.
Use the Calculator Wisely
The on-screen calculator can help, but it can also slow students down if overused. Use it for multi-step arithmetic, decimals, percentages, or checking values. Do not use it for simple calculations that can be done mentally.
Strong Data Insights timing depends on knowing when calculation is necessary and when estimation is enough. During GMAT preparation, students should practise both calculator-supported solving and mental estimation.
Create Timing Benchmarks
Because Data Insights has 20 questions in 45 minutes, students should monitor progress regularly. A practical benchmark is around 7 questions in 15 minutes, 14 questions in 30 minutes, and the remaining questions plus review in the final 15 minutes.
These benchmarks are not rigid rules, but they help prevent late-section panic. If you are behind pace, stop over-investing in difficult questions. Make smart decisions, mark carefully, and move forward.
Review Mistakes by Question Type
After every practice set, classify mistakes by question type and cause. Did you misread a table? Ignore a condition? Use the wrong graph scale? Overcalculate? Miss a verbal clue? Spend too much time on a low-probability question?
An error log helps convert practice into improvement. Students should review not only wrong answers but also slow correct answers. A correct answer that took four minutes may still be a timing problem.
