If you’re wondering what GMAT Critical Reasoning is and how it works, this section of the GMAT Verbal test checks your ability to understand arguments and think logically. In Critical Reasoning, you read a short argument and answer a question that asks you to strengthen it, weaken it, or evaluate it.
To solve these questions correctly, you must know three key parts of every argument: the premise, the conclusion, and the assumption. The premise gives the facts, the conclusion states the main claim, and the assumption is the hidden link that makes the conclusion work. When you can identify these parts quickly, GMAT Critical Reasoning becomes much easier to score well in.
Why is it Important?
The skills tested in the Critical Reasoning section aren’t just relevant for the GMAT; they’re essential for business school and beyond. Whether you’re analyzing market trends, making strategic decisions, or evaluating the viability of a new project, the ability to think critically and logically is key. This section of the GMAT is designed to see if you have what it takes to succeed in these real-world scenarios.
Mastering GMAT Critical Reasoning is essential for several key reasons:
- Direct Impact on GMAT Score: Critical Reasoning questions make up a significant portion of the Verbal section, directly influencing your overall GMAT score. Excelling in this section can significantly enhance your chances of achieving a high score, which is crucial for admission to top-tier business schools. As many top business programs place a strong emphasis on GMAT scores, your performance in Critical Reasoning can be a decisive factor in your application.
- Development of Analytical Skills: The ability to analyze arguments, identify logical flaws, and evaluate reasoning is not only essential for the GMAT but also for your future career in business and management. In the business world, decisions are often based on the analysis of arguments and data, making the ability to think critically and logically a valuable asset. Mastering these skills during your GMAT preparation will serve you well in boardroom discussions, strategic planning, and problem-solving scenarios.
- Foundation for Success in Business School: The logical thinking and reasoning skills that GMAT Critical Reasoning questions test are the same skills that will be required of you in business school. Courses in strategy, finance, and management often involve case studies and complex scenarios where you will need to evaluate arguments, consider different perspectives, and make reasoned decisions. Excelling in Critical Reasoning on the GMAT sets a strong foundation for your academic success in these areas.
GMAT Critical Reasoning Questions Sample
To give you a clearer understanding of what to expect, here’s a breakdown of the common types of
GMAT Critical Reasoning questions:
1. Assumption Questions
These questions require you to identify the unstated assumption that the argument relies on. An assumption is something that the argument takes for granted and is necessary for the conclusion to be valid. Example: “Which of the following is an assumption on which the argument depends?” Understanding assumptions is crucial because if an assumption is false, the entire argument could fall apart.
2. Strengthen/Weaken Questions
These questions ask you to determine how new information might either support or undermine the argument. Strengthen questions require you to find evidence that makes the argument more convincing, while weakened questions ask you to identify information that would diminish the argument’s validity. Example: “Which of the following, if true, would most strengthen the argument?” These questions test your ability to assess the impact of additional evidence on the argument’s overall strength.
3. Inference Questions
Inference questions challenge you to draw a logical conclusion based on the information provided in the argument. Unlike other question types, which focus on the argument’s structure, inference questions require you to deduce what must be true if the premises are accurate. Example: “Which of the following can be inferred from the passage?” These questions test your ability to read between the lines and understand the broader implications of the argument.
4. Evaluation Questions
Evaluation questions ask you to assess the validity of the argument or identify a logical flaw. You might need to determine what information would be most useful in evaluating the argument’s strength or what could potentially weaken the argument. Example: “Which of the following would be most useful to know in order to evaluate the argument?” These questions are about understanding the argument's structure and logic at a deeper level.
5. Boldface Questions
Boldface questions involve analyzing the role of specific parts of the argument (usually highlighted in bold). Typically, these questions ask you to identify the function of the bolded sentences within the argument, such as whether they serve as the conclusion, a supporting premise, or a counterargument. Example: “In the argument, the two portions in boldface play which of the following roles?” These questions require a deep understanding of how different parts of the argument interact.
How to Improve Critical Reasoning Skills Gmat
Improving your Critical Reasoning skills is a strategic process that involves understanding the logic behind arguments and practicing consistently. Here are some tips:
- Study the Argument Structure: Focus on identifying the premise, conclusion, and assumptions in each argument. This will help you better understand the flow of logic and how to approach each question. By breaking down the argument into its core components, you can more easily see where the logic holds and where it might be flawed.
- Practice Regularly: Regular practice is crucial. Use official GMAT practice questions and focus on understanding why the correct answers are right and why the wrong ones are incorrect. The more you practice, the more familiar you will become with the types of logic and reasoning used in GMAT questions.
- Pre-Think Before Answering: Before looking at the answer choices, try to pre-think what a correct answer might be. This can help you narrow down your options more effectively. By anticipating the type of answer that would be correct, you can more quickly identify the right choice when you see it.
- Learn from Mistakes: Review any mistakes you make during practice. Understanding where you went wrong will help you avoid similar errors in the future. Each mistake is an opportunity to learn and improve your reasoning skills.
Common Pitfalls to Avoid
When tackling GMAT Critical Reasoning questions, it’s essential to avoid common pitfalls that can lead to incorrect answers:
- Misinterpreting the Argument: Always make sure you clearly understand the main point of the argument before selecting an answer. Misinterpretation can easily lead to choosing the wrong option. Take a moment to identify the conclusion and ensure that you are addressing the argument correctly.
- Overlooking Key Words: Words like “most,” “least,” “only,” and “all” can significantly alter the meaning of an argument or an answer choice. Pay close attention to these qualifiers as they often change the entire context of the statement.
- Falling for Trap Answers: The GMAT often includes answer choices that seem plausible but don’t directly address the question or introduce irrelevant information. Be cautious of these traps. These answers are designed to mislead you by appealing to surface-level understanding rather than a deep analysis of the argument.
Tips for GMAT Critical Reasoning

Mastering GMAT Critical Reasoning (CR) requires a strategic approach. Start by understanding the basic components of any argument: premises (facts), conclusion (the main point), and assumptions (unstated ideas connecting them). This breakdown is crucial for pinpointing weaknesses in an argument.
Read the question stem first to focus on what’s being asked (e.g., strengthen or weaken), and then deconstruct the passage to identify the core argument. Anticipate the answer before looking at the options, as this reduces confusion from tricky choices. When evaluating answers, eliminate wrong ones systematically by avoiding extreme language like "never" or "always," irrelevant information, or reversed logic.
Use official GMAT practice materials for accuracy and to get familiar with common traps. Manage your time well, aiming for about 2 minutes per question. Finally, always review your mistakes to understand where your reasoning went wrong and why the correct answer is right.
Key Tips Recap:
- Read the question stem first.
- Deconstruct the argument into premises, conclusions, and assumptions.
- Anticipate the answer before reviewing the options.
- Eliminate wrong answers systematically:
- Avoid extreme language, irrelevant info, or reversed logic.
- Use official practice materials.
- Manage your time, around 2 minutes per question.
- Review your mistakes.
