If you have been preparing for your Maths Methods IA2, IA3 or external exam and have come across the terms simple familiar, complex familiar and complex unfamiliar without fully understanding what they mean, you are not alone. The QCAA uses these three categories to classify question types across all Maths Methods assessments and knowing the difference between them changes how you revise and how you approach each exam.
Here is a plain-language breakdown of each type, examples of each question type and how to prepare for them.

KEY ARTICLE INSIGHTS:
In QCE Mathematical Methods, simple familiar, complex familiar and complex unfamiliar questions test different levels of mathematical thinking, not just harder content
Simple familiar questions make up around 60% of IA2, IA3 and the external exam and are the ones you should be getting right every time
Complex unfamiliar questions are not always harder maths. They often just require better problem-solving and a calm starting point
Leaving complex unfamiliar questions blank is one of the most common and avoidable mistakes across all Maths Methods assessments
Simple Familiar Questions in Maths Methods
Simple familiar questions (SF) test skills and procedures you have practised directly in class and in your textbook. The context is recognisable, the method is clear and if you have been keeping up with your work and paying attention in lessons, you should be able to answer these confidently.
In Maths Methods IA2, IA3 and the external exam, simple familiar questions make up roughly 60% of each assessment. They are your most reliable source of marks and the questions you should be getting right every time.
❓What they look like: A simple familiar question might ask you to differentiate a function, calculate a probability using a given distribution or find the area under a curve between two values. One or two steps, a standard procedure and a clear answer.
📚 How to revise for them: Build accuracy through repetition. Work through your textbook exercises and past practice questions until you can complete these quickly and correctly without second-guessing yourself. Rushing simple familiar questions because they look easy is one of the most common ways students lose marks they should have had in both IA3 and the external exam.
Complex Familiar Questions in Maths Methods
Complex familiar questions (CF) involve multiple steps or require you to connect more than one concept to reach an answer. The context is still something you have seen before and the maths involved is from your syllabus, but the path to the answer is not immediately obvious. You need to break the problem down and decide which techniques to apply and in what order.
These make up roughly 20% of IA2, IA3 and the external exam.
❓What they look like: A complex familiar question might ask you to model a real-world situation using a probability distribution, interpret the result and explain what it means in context. It draws on knowledge you have but requires you to apply it across more than one step.
📚 How to revise for them: Practise multi-step problems and make sure you are not just getting to the final answer but also showing clear working at each stage. The QCAA awards marks for method across IA2, IA3 and the external exam, so even if your final answer is wrong, clear working that shows the right approach can still earn you marks.
Complex Unfamiliar Questions in Maths Methods
Complex unfamiliar questions (CU) present familiar mathematical concepts in a context you have not specifically practised. The information is often buried in the wording of the question and you need to interpret what is being asked, identify which mathematical tools apply and build your solution from scratch.
These make up roughly 20% of IA2, IA3 and the external exam.
The important thing to understand is that complex unfamiliar questions are not always harder maths. The calculus or statistics involved might be no more difficult than what appears in a simple familiar question. What makes them complex is the unfamiliarity of the context and the number of steps required to reach an answer.
The biggest mindset shift we try to help students make with complex unfamiliar questions is to stop thinking of them as impossible and start thinking of them as puzzles. The maths is in there. Your job is to find the entry point by identifying the key concept being assessed.
❓What they look like: A complex unfamiliar question might present a real-world scenario you have never seen before and ask you to set up and solve a problem using integration, probability or calculus. The question may combine multiple topics and require you to explain your reasoning as well as show your working.
📚 How to revise for them: Practise identifying the topic being tested before you start writing. When you encounter a complex unfamiliar question in a practice paper, read it carefully and ask yourself which area of the syllabus it is drawing from. Then write down what you know, what you are being asked to find and which method or formula might apply. Starting somewhere is always better than leaving it blank.
For complex unfamiliar questions, we teach students to start by identifying the concept the question is linking to. Then consider what unknown you are being asked to find. From there, you can work out which tools or techniques apply, even if the question looks nothing like anything you have seen before.
How the Same Topic Can Appear Across All Three Types
Here is how the same topic, normal distributions, might appear at each level across IA2, IA3 and the external exam:
Exam Question Type | Example |
Simple Familiar | Find P(X < 5) given X is normally distributed with mean 4 and standard deviation 1.
This is a simple CAS calculation which requires you to know how to navigate your calculation functions and the formatting required for entering mean and standard deviation. |
Complex Familiar | A factory produces items with weights normally distributed with a given mean and standard deviation. Find the probability that a randomly selected item falls within a specified range and explain what this means for quality control. In this question, you have to be able to identify that the question wants you to find a certain probability which you'll write as P(______) as the first part of your solution. A diagram is likely required too to help you further understand what is being asked. Communicate all steps and your mathematical thinking as well as any CAS processes you complete. |
Complex Unfamiliar | A new scenario uses a normal distribution in a context you have not seen before, requires you to identify the appropriate parameters, set up the calculation and interpret the result in the context of the question. Start by noting down the given information first and identifying what they want you find in mathematical terms. The key is not using words. Translate it to variables and values. An average number of sales per week means μ and 'likelihood' or 'chance' refers to probability which may be below P(X < x), between (x1 < X < x2) or above P(x < X) certain parameters. Diagrams are extremely useful in this case. Also consider the use of complements to save you time (e.g. P(X < 1) is the same as 1 - P(1 < X). |
In these examples, you can see that the underlying maths is similar across all three. What changes is how much interpretation, setup and explanation is required.
Common Mistakes Across All Three Question Types in Maths Methods
1️⃣ Simple familiar (SF): Rushing because the question looks easy and making a careless error that costs you a mark you should have had. This happens in IA2 and IA3 just as often as it does in the external exam.
2️⃣ Complex familiar (CF): Skipping steps in your working because you know the answer and then losing method marks when the final answer is wrong.
3️⃣ Complex unfamiliar (CU): Leaving the question blank because it looks too hard. Even a partially correct attempt with clear working can earn method marks in IA2, IA3 and the external exam. A blank page earns nothing.

Frequently Asked Questions
What is the difference between simple familiar, complex familiar and complex unfamiliar questions?
Simple familiar questions test standard procedures in a recognisable context. Complex familiar questions require multiple steps or connecting more than one concept in a familiar setting. Complex unfamiliar questions present familiar mathematics in a new or unpractised context that requires interpretation and problem-solving to work through. All three types appear in Maths Methods IA2, IA3 and the external exam.
How do you answer complex unfamiliar questions in Maths Methods?
Start by reading the question carefully and identifying which area of the syllabus it is drawing from. Write down what you know, what you are being asked to find and which method or formula might apply. Show your reasoning clearly and attempt every part of the question. Even a partially correct response with clear working can earn method marks in IA2, IA3 and the external exam.
How much of the Maths Methods IA3 is simple familiar questions?
Roughly 60% of IA3 is made up of simple familiar questions. The same breakdown applies to IA2 and the external exam. Building accuracy and consistency on simple familiar questions is the fastest way to improve your overall mark across all three assessments.
Should I leave complex unfamiliar questions blank if I am not sure?
No. Leaving a complex unfamiliar question blank guarantees zero marks in IA2, IA3 and the external exam. Even if you are not sure how to reach the final answer, write down what you know, show your reasoning and attempt each part of the question. Partial working that demonstrates understanding of the correct method can still earn you marks.
