Having designed exam questions myself, I know that is exactly what examiners are trying to catch out, and I teach students how to think past it. My name is Chris Cheah, and I am a specialist mathematics tutor covering Year 7 to Year 12, with a particular focus on senior mathematics in Advanced, Extension 1 and Extension 2. I completed a Bachelor of Science (Advanced) at The University of Sydney in 2023, majoring in Mathematics and Financial Mathematics/Statistics as a Dalyell Scholar, graduating with a Distinction WAM. I am currently undertaking a part-time Master of Statistics at UNSW alongside full-time work. I have been tutoring mathematics privately for over 6 years, running continuously throughout university and alongside my professional career. After graduating from university, I joined Matrix Education as a mathematics teacher, teaching across Year 7 to Year 12 Extension 2, and led the development of their hardest HSC Mathematics Advanced exam questions, written to match or exceed the difficulty of real HSC end-of-paper questions. During university, I also worked with Sydney Centre of Mathematics on resource creation, solution writing and student exam marking. I have additionally contributed to a published HSC Mathematics Extension 2 textbook, reviewing and correcting questions and solutions across the syllabus. This experience across teaching, resource development and exam design means I understand HSC questions from the inside, where most students only ever see them from the student's side. With extensive experience designing HSC-style exam questions, I understand how they are structured, the intentional design behind each question, and how examiners can always present a familiar concept in an unfamiliar way. A common mistake students make is trying to rote learn their way through mathematics, but modern HSC exam papers are specifically designed to punish that approach. I focus on developing genuine mathematical understanding and problem solving skills so students can read an unseen question, work out what is actually being asked, and reason through it from first principles. Beyond the classroom, I have worked professionally in applied mathematics and data, first as a Game Design Mathematician in the gaming industry and now as a Data Analyst, which gives me a broader perspective on where mathematics actually leads beyond school. That perspective shapes how I teach. My lessons are tailored to each student. For students who are struggling, I focus on rebuilding fundamentals, identifying weak areas and building genuine confidence through worked examples. For stronger students, I push toward harder exam-style problems, deeper reasoning and extension-level thinking beyond rote method recall. Among students I have worked with, one came to me with only a few months left before their HSC, averaging 50-60% in prior assessments, and lifted to an external HSC mark of 87. Another I worked with long-term improved from around 60% in junior mathematics to scoring 98/100 in Mathematics Advanced and 46/50 in Extension 1. These are just two examples of the range of students I have taught and the improvements that are possible with the right focus. I primarily tutor online. In-person tutoring may be available around Strathfield by arrangement. My base rate is $100/hr for 1-on-1. Feel free to reach out to discuss your needs and whether I would be a good fit.
