ISAT Critical Thinking: Daily Habits to Boost Your Score

The ISAT's Critical Reasoning section does not test memorised knowledge. It tests how well you think. The good news is that critical thinking is a skill you can strengthen through daily habits, well before exam day. Students who build these habits over weeks and months consistently outperform those who rely on last-minute cramming.

Why Daily Habits Matter More Than Cramming

ACER, the organisation that administers the ISAT, explicitly states that the exam measures reasoning skills developed over a long period of time. This means short-term memorisation strategies are largely ineffective. The Critical Reasoning section presents you with passages on unfamiliar topics and asks you to analyse, evaluate, and draw conclusions from them. The only way to get better at this is to practise the underlying thinking skills regularly.

Think of it like physical fitness. You cannot train for a marathon in a single weekend. Similarly, you cannot develop strong critical reasoning skills in a few study sessions. Consistent daily practice builds the mental stamina and analytical reflexes you need on test day.

Read Widely and Actively

Make it a habit to read articles from quality publications covering topics in politics, science, ethics, and social issues. As you read, ask yourself: What is the author's main argument? What evidence supports it? Are there any assumptions that are not stated? This active reading approach mirrors exactly what the ISAT demands.

Good sources include long-form journalism, opinion columns, academic abstracts, and editorial pieces. Avoid passive reading where you simply absorb information. Instead, engage with the text by questioning the author's reasoning at every step. Even 20 minutes of focused, active reading each day will sharpen your comprehension and analytical skills over time.

Engage in Debates and Discussions

Discussing current events or ethical dilemmas with friends and family forces you to articulate your reasoning, consider opposing viewpoints, and defend your position with evidence. These are precisely the skills the ISAT evaluates in its Critical Reasoning passages.

If you do not have someone to debate with regularly, try writing out both sides of an argument on a topic that interests you. Force yourself to make the strongest possible case for a position you disagree with. This exercise strengthens your ability to evaluate arguments objectively, which is critical for identifying assumptions and flaws in ISAT passages.

Analyse Arguments You Encounter

When you see an advertisement, a political speech, or an opinion piece, practise breaking it down: What claim is being made? What evidence is offered? Is the reasoning logical, or are there fallacies? Over time, this becomes second nature and translates directly to faster, more accurate performance on the test.

Pay particular attention to common logical fallacies such as appeals to authority, false dichotomies, circular reasoning, and straw man arguments. Being able to spot these quickly gives you an advantage on ISAT questions that ask you to identify weaknesses in an argument.

Write Short Summaries

After reading an article or watching a documentary, write a brief 3 to 4 sentence summary capturing the main argument and key evidence. This forces you to distinguish essential information from background details, a crucial skill for the comprehension-heavy passages on the ISAT.

Try to capture not just what was said, but why it matters and whether the reasoning was convincing. Over time, this summarisation habit trains your brain to quickly identify the core of any argument, which is exactly what you need to do under time pressure during the exam.

Question Everything You Read

Develop the habit of asking critical questions about every piece of information you encounter. When you read a news headline, ask yourself: What evidence would I need to verify this claim? When you read a statistic, ask: How was this data collected? Is the sample size large enough? Could the data be interpreted differently?

This questioning mindset is the foundation of critical thinking. The ISAT rewards students who can look beyond the surface of an argument and evaluate its underlying logic and evidence.

Practice with Purpose

Combine these daily habits with structured practice using the ISAT Exam Prep app. Work through Critical Reasoning question sets and review the explanations carefully, especially for questions you got wrong. The combination of everyday thinking habits and focused exam practice is the most effective preparation strategy.

Set a daily target, such as 10 to 15 questions per day, and stick to it. Consistency matters more than volume. A student who does 10 questions every day for 8 weeks will almost always outperform a student who does 200 questions in a single weekend.
