## Why MSR Makes or Breaks Your Data Insights Score

Multi-Source Reasoning (MSR) presents candidates with **two or three tabs of dense information**—ranging from corporate memos and email exchanges to financial tables and experimental lab results—followed by a set of interconnected questions (often Yes/No trichotomies or multiple-choice).

Because MSR prompts take up substantial cognitive bandwidth, test-takers who lack a systematic intake process spend 5+ minutes per set, derailing their entire 45-minute Data Insights pacing.

### Hack #1: Execute the 45-Second Tab Census

Do **not** read every word of every tab on initial encounter. Instead, execute a 45-second structural survey:
* **Tab 1:** Identify who is communicating and what policy or problem is under debate.
* **Tab 2:** Note whether it contains opposing viewpoints, supplementary rules, or numerical criteria.
* **Tab 3:** Determine what statistical variables or dates are tracked in any table or graph.

Your goal is not memorization; it is building a mental roadmap so you know *where* to retrieve answers.

### Hack #2: Read the Prompt Stem First Before Deep Reading

Before analyzing text in depth, examine the question stem. MSR questions are hyper-specific:
* If Question 1 asks: *"According to the CFO in Memo B, what minimum ROI is required for Project Delta?"*
* You immediately navigate to Tab 2, find the `ROI` keyword, and extract the figure in 20 seconds.

### Hack #3: Beware the "Yes/No" Trichotomy Interdependence

In MSR questions containing three sub-parts (e.g. Statements A, B, and C where you must select Yes or No for each):
* You must get **all three correct** to earn credit for the question.
* Often, Statement 1 and Statement 2 require simple lookup, while Statement 3 requires reconciling an apparent contradiction between Tab 1 and Tab 3.
* If two tabs present conflicting data, Tab 2 or 3 usually introduces an *exception clause* or *phase-in date*.

### Hack #4: Use the Table Sort Dropdown Aggressively

When an MSR tab includes tabular data:
* Never manually scan 20 rows of numbers.
* Click the column header to sort alphabetically or numerically.
* This immediately clusters maximums, minimums, or departmental categories.

### Hack #5: The 3-Minute Strategic Bailout

If you find yourself past the 3:00 mark on a single MSR sub-part:
1. Make your best logical inference.
2. Bookmark the question using the GMAT Focus review flag.
3. Advance to the remaining questions to protect your overall section score.
