GMAT Focus Data Insights: what the section tests and how GMAC scores it

Data Insights carries one third of your GMAT Focus total score, so it deserves a third of your study time. It is also the section where strong quant students lose points to reading errors and strong verbal students lose points to arithmetic under a clock. This guide covers what the 20 questions ask, how GMAC turns your answers into a score, and how to prepare for each format without wasting weeks.

The section in numbers

• 20 questions in 45 minutes, an average of 2 minutes 15 seconds per question.
• Five formats: Data Sufficiency, Multi-Source Reasoning, Table Analysis, Graphics Interpretation, and Two-Part Analysis.
• An on-screen calculator, available in this section only. Quant gives you none.
• A section score from 60 to 90, which GMAC reports next to your Quant and Verbal scores.
• Equal weight with Quant and Verbal in the 205–805 total. On the previous edition of the exam, the Integrated Reasoning score sat outside the total; Data Insights counts in full.
• You choose the order of the three sections at the start of the exam, and you may take one optional 10-minute break after the first or second section.

What each format asks you to do

Data Sufficiency

You read a question and two statements, then decide which statements give enough information to answer it. You never need the answer itself. The five choices never change, so your work is one judgment about each statement alone and, when both fail, one about the two together. On GMAT Focus these questions moved from Quant into Data Insights. Most still test algebra and arithmetic, but some test pure logic with no numbers at all.

Multi-Source Reasoning

Several tabs hold text, tables, or charts, such as an email, a memo, or a data table. A set of questions follows: some ask you to mark statements yes or no, or true or false, and others are multiple choice. You win these by finding information quickly and by combining a rule from one tab with the numbers in another.

Table Analysis

A table that you can sort by any column comes with several statements, and you mark each one yes or no, true or false, or a similar pair. Sorting replaces most of the arithmetic: a median, a rank, or a count of rows that pass a threshold falls out of a sorted column.

Graphics Interpretation

A graph sits above sentences with dropdown blanks. You read the graphic, estimate or compute the value each blank needs, and choose from the dropdown. GMAC names scatter plots, x/y graphs, bar charts, pie charts, and statistical curve distributions among the graphics it uses.

Two-Part Analysis

A short scenario leads to a table with two answer columns that share one list of options. You choose one option per column. GMAC writes some of these questions as quantitative problems, with two conditions to satisfy at once, and others as verbal ones, such as picking a strengthener and a weakener for the same argument; some mix the two.

How GMAC scores Data Insights

The section is computer-adaptive: the exam chooses each question in light of your answers so far, generally moving harder after correct answers and easier after misses. GMAC then computes your section score from three things: how many questions you answer, which ones you answer correctly, and the difficulty of each question you see. Two candidates with the same number of correct answers can therefore earn different scores.

Three rules follow from that design, and each one changes how you should play the section.

1. Multi-part questions are all or nothing. A Table Analysis question with three statements, a Graphics Interpretation question with two dropdowns, and a Two-Part Analysis question with two columns each earn credit only when every part is correct. Two right out of three scores the same as zero.
2. Unfinished sections cost points. GMAC lowers your score for every question you leave unanswered when time runs out, so plan your pace to reach the last question.
3. You can change up to three answers. Question Review & Edit lets you bookmark any number of questions and, with the time you have left at the end of the section, change as many as three answers. Spend those changes on questions you narrowed to two options, not on questions where you skipped the thinking.

GMAC reports the section score on the 60 to 90 scale and combines it with your Quant and Verbal scores into the 205–805 total, where every score ends in 5. GMAC weights the three sections equally, so a Data Insights point counts exactly as much as a Quant point.

Why Data Insights trips up strong candidates

Most candidates arrive with a background that fits one of the other two sections. Confident calculators trust their arithmetic and read charts too fast; careful readers read every word and then stall on a percent change with a calculator in front of them. The section punishes both habits, and it usually does so with math you already know. What it demands is a procedure you can follow under time, and you can train that in a few weeks.

How to prepare, format by format

1. Data Sufficiency: learn one decision procedure and run it every time. Classify the question as a value question or a yes-or-no question, test each statement alone, and combine only when both fail. Our Data Sufficiency guide walks through the procedure step by step.
2. Multi-Source Reasoning: practice the first minute. Skim each tab and write three words about what it holds before you read the first question. Candidates who skip this step reread the tabs for every question and run out of time.
3. Table Analysis: sort before you compute. For each statement, name the column and the operation, sort by that column, then decide. Keep a short list of the operations that recur: median, rank, percent change, ratio, conditional count.
4. Graphics Interpretation: read the frame first. Title, axis labels, units, where each axis starts, legend, footnote. Then estimate, and calculate only when the dropdown options sit close together.
5. Two-Part Analysis: decide in the first thirty seconds whether the two columns depend on each other. Linked columns need one setup that holds both conditions; independent columns work as two short questions.

A four-week plan

• Week 1: take a timed set of 20 mixed Data Insights questions to find which formats cost you time and which cost you accuracy. Track the two separately; they need different fixes.
• Week 2: drill your two weakest formats untimed until the procedure feels automatic, then add the clock back.
• Week 3: run mixed timed sets of 10 and review every miss with a written cause: misread, wrong operation, arithmetic slip, or time pressure.
• Week 4: take full 45-minute sections and practice the pacing decisions, including letting one question go at the three-minute mark.

The mistakes that cost the most

• Treating Data Insights as a smaller section because it comes with a calculator. It carries a third of your total.
• Spending five minutes on one Multi-Source Reasoning question. The set shares its sources, so time you save on reading spreads across every question in it.
• Checking two of three statements in Table Analysis and guessing the third. All or nothing means the guess decides the whole question.
• Solving Data Sufficiency problems to the end. The question asks whether you could, not what the answer is.
• Running out of time with questions unanswered. GMAC lowers your score for each one, so a steady pace beats a perfect first half.

GMAX holds thousands of original Data Insights questions across all five formats, rates each one on the GMAT score scale, and shows an explanation after every answer, with an on-screen calculator as on the exam. The free plan gives you five questions a day, enough to run these procedures daily until they become automatic.
