GMAT practice test: a full-length GMAT Focus mock, section by section

The GMAT Focus exam has three sections, each independently timed. Quantitative Reasoning is 21 Problem Solving questions in 45 minutes, with no on-screen calculator. Verbal Reasoning is 23 questions in 45 minutes, covering Critical Reasoning and Reading Comprehension. Data Insights is 20 questions in 45 minutes, covering Data Sufficiency, Multi-Source Reasoning, Two-Part Analysis, Graphics Interpretation, and Table Analysis, with an on-screen calculator available throughout.

A full-length mock covers all three sections back to back, in whichever order GMAT Focus lets you choose, for a total of 64 questions across 135 minutes of exam time, not counting breaks. The exam allows one optional break between sections. Total seated time including the break is typically around two and a half hours. Sitting the full length without skipping a section is the only way to build the stamina and pacing discipline that the real exam requires.

The hardest thing a full-length mock teaches that practice sets cannot is what it feels like to reach question 17 of Data Insights having already sat through 44 minutes of Quant and 44 minutes of Verbal. The cognitive load of managing three sections in sequence, with a cumulative fatigue effect, is not something you can simulate from the inside of a single section drill.

This has practical consequences for strategy. The time budget for each section, roughly two minutes per question on average across all three, is straightforward in isolation. Under real exam conditions, section two and section three run against a mental load that section one did not. Knowing this from a mock, and adjusting your pacing strategy for it, is different from knowing it abstractly. The mock is also where your section-ordering choice gets stress-tested: GMAT Focus lets you choose the order of your three sections, and the choice that feels right on paper often needs to be recalibrated after your first full sit.

After a PrepLattice full-length mock, section-by-section diagnostics show you how your accuracy broke down within each section and across the three sections as a whole. Within each section, you can see your accuracy by question type and difficulty band, plus the time you spent on each question. Across sections, you can see whether your accuracy held through all three sections or fell in a pattern that points to fatigue or ordering effects.

The diagnostic is not a score predictor in the sense of a guarantee. It is a map of where your practice time is best spent between now and your test date. If your Data Insights accuracy drops sharply in the last third of the section, the diagnostic tells you that pacing within DI is the priority, not adding more question volume. If your Verbal accuracy falls in the second half of the section, the diagnostic suggests a stamina issue rather than a skill gap on any specific question type. The action you take after each mock is what produces the improvement the next one measures.

Treat each full-length mock as a data-collection event, not a performance. Before you start, decide your section order and your time budget per question. Sit it under real conditions: no pausing, no looking things up, no checking your phone. After you finish, spend at least as long reviewing it as you spent sitting it. The review is where the practice happens.

In the review, do not just check which answers were wrong. For each wrong answer, identify the step where your reasoning broke and what you would do differently the next time that structure appears. For each answer where you spent significantly more time than the section average, identify whether the extra time produced a right answer, which is worthwhile, or a wrong answer, which is doubly costly. A mock with disciplined review is more valuable than two mocks reviewed casually. PrepLattice saves your complete attempt history so you can compare performance across mocks and see whether your targeted practice between sittings is moving the right metrics.

Full-length GMAT Focus mocks are part of the Committed plan, which also opens the custom-set builder and section-by-section diagnostics. The Committed plan is a one-time payment with no auto-renewal.

If you are not ready for a full mock yet, the free Daily Five is available to every signed-up member at no cost: five fresh questions each day, drawn from the three GMAT Focus sections with a rotating mix, with every miss explained and your history saved. The daily set is the right tool for building consistent reps and identifying your question-type weaknesses before you invest a full sit in a mock. When your daily accuracy has reached a level where you want to stress-test it over a full exam, that is the point where a mock starts returning the most information.
