This is the course outline for Mathematical Methods Units 3 and 4.
Mathematical Methods Units 3 and 4 build on your earlier study of functions, expanding to combinations of functions, algebra, calculus, probability, and statistics. These concepts are explored in both practical and theoretical contexts to deepen your mathematical understanding and prepare you for further study.
Across Units 3 and 4, you will study four key areas: Algebra, Number and Structure; Functions, Relations and Graphs; Calculus; and Data Analysis, Probability and Statistics. These areas are developed progressively, starting in Unit 3 and continuing into Unit 4, with content selected to ensure a clear and logical learning pathway.
In Unit 3, you will typically focus on algebraic functions, graphing and analysing their key features, and applying differentiation techniques. This includes work from the Functions, Algebra, and Calculus areas of study. In Unit 4, you continue with integration and its applications—such as finding areas under curves and working with probability distributions. You’ll also explore random variables, probability distributions, and the distribution of sample proportions.
Throughout both units, you are expected to apply a wide range of mathematical processes, including arithmetic, algebraic manipulation, solving equations, graph sketching, and using calculus techniques like differentiation and integration. You will also interpret and apply probability and statistical inference.
You should be confident in both mental and written methods of estimation and computation. Technology—such as graphing tools, symbolic calculators, and statistical software—will be used to support learning, problem-solving, and assessment where appropriate.
To be awarded a satisfactory result for a unit, you must demonstrate the outcomes specified for that unit. Your teacher will use a variety of learning activities and assessment tasks to give you different ways to show your understanding of the key knowledge and skills.
Your level of achievement in Units 3 and 4 will be determined by School-assessed Coursework and examinations.
School-assessed Coursework for Unit 3 contributes 24% to your final study score.
School-assessed Coursework for Unit 4 contributes 16% to your final study score.
The remaining 60% of your study score comes from two end-of-year examinations, each worth 30%.
Examination 1 includes short-answer and some extended-answer questions across all areas of study related to Outcome 1. It is designed to assess your knowledge of mathematical concepts, your ability to perform mathematical algorithms without technology, and your skill in applying concepts and techniques.
Examination 2 includes multiple-choice and extended-answer questions covering all areas of study with an emphasis on Outcome 2. This exam is designed to assess your ability to understand and communicate mathematical ideas, and to interpret, analyse, and solve both routine and non-routine problems.

Thank you so much! I have been using your videos to study for my upcoming math exam and I have never felt so confident! I have never realised how easy math really is until I have come across your channel. Now that I finally understand how to solve questions from Cambridge I no longer “despise” maths
Thank you so much for this it was easy to understand and not boring at all you made math fun for me. I love your videos
You have a special way of teaching that is so awesome ⭐️I have watched so many other videos and looked over random notes and nothing helped, until I found your video! Thank you so much, you’re a life saver!
Hii! I am a year ten student and I have upcoming exams! And I really struggle with math, however your videos have helped me understand and get a great concept of the subject (not sure if that makes total sense haha) but I just wanted to say thank you !! and I will definitely be notifying my peers about your channel!.
Lovely stuff mr maffs guru
