GMAT Multi-Source Reasoning strategies
Multi-Source Reasoning presents information across multiple tabs and asks you to synthesize it. These strategies cover the core principle of reading each source separately, the trap of mixing up which source says what, and a step-by-step walkthrough you can run on every source set.
The core principle
Each tab is a self-contained source. Multi-Source Reasoning gives you two or three tabs of text, tables, or emails, then asks questions that require you to pull the right claim from the right source. The skill is keeping the sources straight. Read each tab once, hold its key claims in mind, and answer each question from the source it points to. Most questions draw from one tab at a time, not all of them at once.
The most common trap
Mixing up which source says what
A claim that appears in the first tab is not in the second, even if the two tabs cover related material. Test writers place an answer choice that is true of one tab but attributed to another, or a statement that is true in the real world but not stated in any source. The correct answer must be supported by the specific source the question names, not by your outside knowledge or by a different tab. Track which tab each claim came from before you commit to an answer.
Step-by-step strategy
When to use: any question set that presents multiple tabs or sources and asks you to synthesize or evaluate claims.
- 1Read each tab once, start to finish. Do not jump back and forth on the first pass.
- 2Note the key claim or data point from each tab in one short phrase per tab.
- 3Read the question and identify which source it points to.
- 4Answer from that source only. Confirm the claim is actually stated there, not inferred from another tab.
When not to use: when a question asks you to combine two sources, use the same per-source read first, then reconcile the two claims in the final step.
