How to Prepare for the ISAT: A Step-by-Step Study Plan

Your Step-by-Step Guide to Preparing for the ISAT

Preparing for the International Student Admissions Test (ISAT) can feel challenging, especially if you are unfamiliar with the test format, question types and time limits.

Unlike examinations that focus on specific school subjects, the ISAT assesses your critical reasoning and quantitative reasoning skills. This means that effective preparation involves more than memorising information or reviewing academic content.

A strong preparation strategy starts with understanding the test, becoming familiar with its question types, practising under timed conditions and learning from your mistakes.

For students in Singapore planning to apply to selected medical and health-related programmes overseas, preparation should also fit around school commitments, university applications and other responsibilities.

This guide outlines a practical, step-by-step approach to preparing for the ISAT.

Step 1: Understand the ISAT Before You Start Preparing

Before beginning your preparation, take some time to understand what the ISAT assesses and how the test is structured.

The ISAT is a three-hour online multiple-choice assessment consisting of 100 questions. It focuses on two main areas:

• Critical Reasoning: Understanding and analysing information, evaluating arguments, drawing conclusions and applying ideas.
• Quantitative Reasoning: Analysing information, interpreting data, solving problems and making decisions using mathematical relationships.

The test does not assess knowledge from a specific academic curriculum. Instead, the information required to answer each question is provided within the question or stimulus material.

Before starting your preparation, familiarise yourself with:

• The ISAT test format and question types
• The two reasoning areas
• The online test interface
• The available time limit
• How to navigate between questions
• How to review and change your answers

Understanding the test structure can help you approach your preparation more confidently.

Tip: Do not assume that strong academic knowledge alone will guarantee a high score. Focus on understanding information, identifying patterns and applying logical reasoning.

Step 2: Start With a Diagnostic Assessment

Once you understand the test format, assess your current abilities.

A diagnostic assessment can help you identify:

• Which question types you find most challenging
• Whether you struggle more with critical or quantitative reasoning
• How accurately you interpret written information and data
• How much time you spend on individual questions
• Whether your main challenge is accuracy, speed or both

You do not need to achieve a high score during your first practice session.

The purpose of a diagnostic assessment is to understand your starting point and identify areas that require further improvement.

After completing the assessment, review your performance carefully. Instead of focusing only on your overall score, look for patterns in your mistakes.

Remember: Your first practice result is a starting point for your preparation, not a prediction of your final performance.

Step 3: Become Familiar With ISAT Question Types

The ISAT does not require preparation based on a particular school subject. However, becoming familiar with the types of questions and information presented can help you prepare more effectively.

Critical Reasoning

Critical reasoning questions may require you to:

• Understand information presented in written passages
• Identify the main idea or relevant details
• Draw conclusions from the information provided
• Evaluate arguments
• Apply ideas to a new situation

Practise reading carefully and distinguishing between information that is directly supported by the passage and assumptions that are not.

Quantitative Reasoning

Quantitative reasoning questions may involve:

• Interpreting tables and graphs
• Identifying numerical relationships
• Applying mathematical concepts
• Comparing information
• Solving problems using the data provided

You do not necessarily need advanced mathematical knowledge for every question. Instead, focus on understanding the information and selecting an appropriate approach.

Tip: Read the stimulus material carefully before looking at the answer options. Make sure you understand what the question is asking before beginning your calculations or reasoning.

Step 4: Use Official ISAT Practice Materials

After becoming familiar with the question types, begin practising with official ISAT preparation materials.

ACER provides official ISAT practice tests that are designed to help candidates understand the types and styles of questions they may encounter. The official preparation materials are available through an ACER account.

When using practice materials, focus on:

• Understanding the reasoning behind each answer
• Identifying question types that cause difficulties
• Reviewing questions you answered incorrectly
• Recognising patterns in your mistakes
• Improving your approach to unfamiliar information

Avoid measuring your progress only by the number of questions you complete. The quality of your review is an important part of preparation.

Review Your Mistakes

After answering a question incorrectly, ask yourself:

Why did I get this question wrong?

Was it because you:

• Misunderstood the information?
• Misread the question?
• Used an unsuitable approach?
• Made a calculation error?
• Spent too much time on one question?
• Choose an answer without reviewing all the options?

Understanding the reason behind a mistake can help you improve your approach to similar questions in the future.

Step 5: Develop Your Time Management Strategy

The ISAT is a time-limited assessment, so preparation should gradually include time management practice.

ACER recommends working steadily through the test and avoiding spending too much time on one question. Since all questions have the same value and incorrect answers do not receive a mark deduction, candidates are encouraged to attempt as many questions as possible.

You can develop your time management skills in stages.

Early Preparation

Focus on understanding question types and improving accuracy without placing too much pressure on speed.

Mid-Stage Preparation

Begin timing smaller groups of questions. Identify which questions take the longest and consider when to move on.

Later Preparation

Complete longer practice sessions under timed conditions. Practice maintaining concentration while working through different question types.

The goal is not simply to answer questions quickly. It is to develop a balanced approach that allows you to work accurately and make effective use of the available time.

Step 6: Practise Reading and Interpreting Information

Because the ISAT assesses reasoning skills rather than specific subject knowledge, reading widely and thinking critically can support your preparation.

ACER explains that ISAT preparation should include becoming familiar with question types, reading widely and developing the ability to think critically about information.

You can practise by engaging with different types of content, such as:

• News articles
• Opinion pieces
• Informational texts
• Graphs and tables
• Reports and research summaries
• Articles discussing social or scientific issues

When reading, consider:

• What is the main argument?
• What evidence supports the conclusion?
• Are there assumptions in the information?
• What can reasonably be concluded?
• How is the information presented visually or numerically?

These activities can help you become more comfortable interpreting unfamiliar material.

Tip: You do not need to memorise every piece of information you read. Focus on understanding the meaning, structure and relationships within the material.

Step 7: Create a Personalised Study Plan

There is no single preparation schedule that works for every ISAT candidate.

Your study plan should depend on:

• Your current reasoning skills
• Your target test window
• Your school or university workload
• Your strengths and weaknesses
• The amount of time you can consistently dedicate to preparation

A useful study plan could include the following stages:

The length of each stage should be adapted to your individual needs. Avoid following a fixed schedule simply because it worked for another student.

Consistency and purposeful practice are more useful than studying for long hours without a clear focus.

Step 8: Focus on Your Weaknesses

As you continue practising, use your results to identify the areas that require the most attention.

For example:

• If you understand the question but take too long: Practise identifying the key information and choosing an efficient approach.
• If you answer quickly but make frequent mistakes: Slow down and review how you interpret the question.
• If you struggle with graphs or tables: Practise identifying trends, comparisons and relationships in the data.
• If written passages are challenging: Focus on identifying the main idea, supporting evidence and logical conclusions.

Your study plan should change as your performance develops.

You do not need to spend the same amount of time on every question type. Prioritise the areas where targeted practice can help you improve.

Step 9: Practise Test-Taking Strategies

In addition to practising questions, develop strategies that help you manage the test effectively.

ACER recommends several approaches, including reading all answer options, avoiding spending too long on one question and returning to questions later when time allows.

During practice, consider the following strategies:

Read the Question Carefully

Make sure you understand what the question is asking before selecting an answer.

Review All Answer Options

Even if one answer seems correct, read the other options before making your final choice.

Avoid Spending Too Long on One Question

If a question is taking too much time, select your best answer and continue. You can return to the question later if time allows.

Attempt as Many Questions as Possible

Since incorrect answers do not receive a mark deduction, leaving questions unanswered may reduce your opportunity to earn marks.

The most effective strategy may differ between candidates. Use practice sessions to identify an approach that suits your working style.

Step 10: Prepare for Test Day

Your preparation should also include understanding the technical and administrative requirements of the ISAT.

The ISAT is delivered through remote proctoring, so candidates should review the official test-day requirements before their scheduled session.

Before test day, make sure you understand:

• The computer and internet requirements
• The identification documents you need
• The permitted items during the test
• The test-day procedures
• How to access the testing application
• What to do if you experience a technical issue

You should also prepare your testing environment in advance.

Get Enough Rest

Avoid relying on last-minute preparation the night before your test. Make sure you have enough time to rest and prepare your testing space.

Being familiar with the test process can help you focus on the assessment instead of worrying about avoidable technical or administrative issues.

What About ISAT Preparation Courses?

ACER states that ISAT preparation courses are not recommended, authorised or associated with ACER. The organisation also advises candidates to assess whether a preparation course provides reliable evidence of its potential benefits before paying for it.

Official preparation materials should therefore be an important starting point for every candidate.

However, some students may seek additional structured support if they:

• Need help creating a preparation schedule
• Want personalised feedback
• Find it difficult to maintain a consistent routine
• Need support identifying their weaknesses
• Want guidance on test-taking strategies

The right preparation approach depends on your learning preferences, goals and individual needs.

Common ISAT Preparation Mistakes to Avoid

1. Preparing Through Memorisation Alone

The ISAT assesses reasoning skills rather than knowledge from a specific academic curriculum. Focus on understanding and applying information instead of relying only on memorisation.

2. Practising Without Reviewing

Completing many questions without analysing your mistakes may limit the value of your preparation.

3. Spending Too Long on One Question

Time management is an important part of the test. Practice moving forward when a question is taking too much time.

4. Focusing Only on Your Practice Score

Your score can show how you performed, but reviewing your mistakes can help you understand how to improve.

5. Using Unverified Preparation Resources

Check whether preparation materials accurately reflect the current ISAT format and requirements. Use official ACER information as your main reference.

6. Leaving Preparation Until the Last Minute

Give yourself enough time to become familiar with the test format, practise different question types and develop a suitable study routine.
