GMAT Data Insights
Multi-Source Reasoning
Retrieve only the relevant facts across tabs or sources without trying to memorize the entire information set.
Mindset
Multi-Source Reasoning rewards targeted retrieval.
You do not need to learn every tab. You need to find the source that contains the fact required by the current question.
Framework
Use this retrieval sequence.
- 01Read the question first.
- 02Identify the key noun, metric, or claim.
- 03Predict which source is most likely to contain it.
- 04Open that source and scan for the target.
- 05Check another source only if the answer depends on it.
Definition trap
Similar terms can have different definitions across sources.
A label such as "revenue" may mean gross revenue in one tab and net revenue in another. Use the definition attached to the specific source.
Efficiency
Do not open every tab before you know the question.
That creates memory load and makes similar facts harder to distinguish.
Mental map
Build a tiny mental index instead of a full summary.
For example: Tab 1 = policy, Tab 2 = monthly data, Tab 3 = customer comments. Then retrieve details when needed.
Cross-source claims
When a claim combines sources, verify each part at its source.
Do not let a true fact from one tab make an unsupported second fact feel true.
Mini application
Try this: a question asks whether a policy threshold was met in March.
Which source should you inspect first: policy text, monthly data, or customer comments?
Solution
Start with the policy text to identify the threshold, then check March in the monthly data.
The task requires a definition from one source and a measured value from another.
Remember this
Retrieve; do not memorize.
Question first, likely source second, targeted scan third.
