ISAT Critical Reasoning Practice Material

The Critical Reasoning section of the ISAT focuses on your ability to comprehend and analyse information. You'll be presented with passages from humanities and social sciences and asked to draw conclusions, understand ideas, and evaluate arguments. This section makes up half of your total ISAT score, so thorough preparation is essential.

What Does the Critical Reasoning Section Test?

This section is not about memorising facts. It assesses how well you can process new information under time pressure. The passages cover topics you are not expected to have prior knowledge about. Instead, all the information you need to answer the questions is contained within the passage itself. The key skills being tested include:

Comprehension: Understanding the main idea and supporting details of a passage.
Analysis: Breaking down complex arguments into their component parts, identifying premises and conclusions.
Evaluation: Judging the strength of an argument, spotting assumptions, and identifying flaws in reasoning.
Inference: Drawing logical conclusions from the information provided, even when they are not explicitly stated.

Why is Critical Reasoning Important?

Universities look for candidates who can think logically and make sound judgments. These are essential skills for any aspiring medical or dental professional. Doctors and dentists must constantly evaluate information from patients, research, and clinical data to make decisions. The Critical Reasoning section of the ISAT is designed to measure whether you have the foundational thinking skills needed for these careers.

A weak performance in this section can significantly lower your overall ISAT score, even if you perform well in Quantitative Reasoning. Since both sections carry equal weight, you cannot afford to neglect either one.

Types of Questions You Will Encounter

Critical Reasoning questions typically fall into several categories:

Main idea questions: These ask you to identify the central argument or purpose of a passage. Focus on what the author is trying to communicate rather than getting lost in specific details.
Inference questions: These require you to determine what can logically be concluded from the passage, even if it is not directly stated. Be careful not to go beyond what the text supports.
Assumption questions: These ask you to identify unstated beliefs that the author relies on to make their argument. Look for gaps between the premises and the conclusion.
Strengthening or weakening questions: These ask you to choose an answer that either supports or undermines the argument presented. Think about what additional evidence would make the argument more or less convincing.
Vocabulary in context questions: These test your ability to determine the meaning of a word based on how it is used in the passage, not its most common dictionary definition.

How to Practice Effectively

Read widely: Engage with complex articles, opinion pieces, and academic papers from a variety of disciplines. Publications covering politics, philosophy, history, and social commentary are particularly useful because they mirror the style of passages found on the ISAT.
Identify arguments: As you read, practise pinpointing the main thesis, the premises that support it, and the conclusion the author reaches. Ask yourself whether the reasoning is valid and what assumptions are being made.
Practise under timed conditions: Time pressure is one of the biggest challenges on the ISAT. With roughly 1 minute and 48 seconds per question, you need to read passages quickly and accurately. Use the ISAT Exam Prep app to take timed practice sets that simulate the pace of the real exam.
Review your mistakes: After completing a practice set, spend time reviewing every question you got wrong. Understand why the correct answer is right and why your chosen answer was wrong. This review process is where the real learning happens.
Build a daily reading habit: Consistent exposure to complex texts improves your reading speed and comprehension over time. Even 20 minutes of focused reading each day can make a noticeable difference over several weeks of preparation.

Common Pitfalls to Avoid

Reading too slowly: Trying to understand every single word in a passage wastes valuable time. Focus on grasping the overall argument and structure instead.
Bringing outside knowledge: Answer questions based solely on what the passage says, not on what you already know about the topic.
Choosing the first plausible answer: Always read all answer options before making your selection. The best answer is sometimes not the most obvious one.

Recommended Preparation Timeline

Start your preparation at least 8 to 12 weeks before your test date. Begin with untimed practice to build your understanding of question types, then gradually introduce time constraints. In the final two weeks before your exam, focus exclusively on full-length timed mock tests to build stamina and refine your pacing. The ISAT Exam Prep app provides structured question banks and full-length mock tests designed specifically for this progression.
