Understand the GMAT exam
The GMAT assesses reasoning for graduate business study. The full exam has 64 questions across three sections: 2 hours 15 minutes of testing, plus one optional 10-minute break.

Section order, bookmarks and answer changes
Choose your section order. Take the optional break after the first or second section. You can bookmark questions as you go. Review becomes available after answering every question in the section, only if time remains. You may review questions and change up to three answers per section. Review uses the remaining section time; it does not provide extra time.
How scores work
Official GMAT scores
Each section is scored from 60 to 90 in one-point steps. The Total Score ranges from 205 to 805 in ten-point steps. All three sections contribute equally.
Scoring considers the characteristics, including difficulty, of questions answered correctly and incorrectly, and the number left unanswered. It is not a simple percentage-correct calculation. Unanswered questions incur a penalty.
Percentiles compare performance with other test takers and are updated annually. They are different from the percentage of questions answered correctly.
Your results on this platform
Practice and lesson simulations report performance on the questions you attempted and identify skills to revisit. These results are learning diagnostics, not official GMAT scores or validated score predictions.
For example, 8 correct answers out of 10 means 80% accuracy on that exercise. It does not imply a GMAT section score of 80 or an 80th-percentile result. Short lesson pilots are not full-length official sections.
Meet the five Data Insights question types
Data Sufficiency
Decide whether the statements provide enough information; distinguish a definite answer from multiple possible answers.
Table Analysis
Sort data and test claims against the relevant rows, units and conditions.
Graphics Interpretation
Read scales and relationships, then select answers that complete statements about the graphic.
Multi-Source Reasoning
Combine evidence across sources and separate supported conclusions from assumptions.
Two-Part Analysis
Solve two linked requirements and choose one answer for each part from a shared list.
Study each concept, work through examples, practise independently, then use your report to revisit weak skills before attempting the separate simulation questions.
