Read like an auditor across tabs
Multi-Source Reasoning (MSR) gives you two or three tabs — a passage, a table, a chart, an email — and three questions that draw on them, shown one at a time. The information is split deliberately: the answer usually lives in the combination of sources, or in the seam where they don't quite agree.
The response shapes
- Multiple choice — five options, pick one.
- Conditional ("yes/no") rows — a condition, then three rows you each mark yes/no or true/false. ⚠️ All three rows must be correct to earn the question — there's no partial credit.
The method
First pass = map, don't memorize. Spend ~30–45 seconds learning what each tab contains and in what units — "Tab 1: policy rules; Tab 2: monthly sales table; Tab 3: an email with one extra constraint." You'll return to the tabs for specifics; you only need to know where each fact lives.
Then, for every question:
- Decide which source(s) it needs. Answering from the wrong tab — or from your own knowledge of the topic — is the designed failure mode.
- Watch the seams. Expect a number in one tab and a percentage in another that almost reconcile, or a definition in the text that changes how a table column must be read. Questions are built on those frictions.
- For yes/no rows, judge each row independently against the stated condition, then re-check all three before committing.
The reading is an investment. Three questions share one set of tabs — so a careful first map pays off three times. Don't skim it to "save time"; rushing the map taxes every question.
Conflicting sources are the point, not a printing error. When two tabs disagree, that contradiction is usually the answer to a "which statement is best supported / which sources conflict" question — don't silently pick one and move on.
A typical seam. Tab 1 (memo): "Bonuses go to reps who beat their quota by at least 10%." Tab 2 (table): each rep's quota and actual sales. A row asks: Rep R earned a bonus. You must combine the rule (Tab 1) with R's numbers (Tab 2) — neither tab answers it alone. That cross-source step is exactly what MSR tests.
You can't return to a previous screen. Because MSR shows questions in sequence, once you click past a screen it's locked. Resolve each screen fully before advancing.
Checklist
- Map each tab's content and units before answering
- For each question, identify the source(s) it requires
- Combine across tabs; suspect the seams where sources meet
- Answer from the tabs only — never outside knowledge
- yes/no rows: all three must be right, so verify each
