Kenneth Clarkson

Founder & IB Mathematics Tutor

I taught IB maths at Kristin School — one of New Zealand's leading IB schools — and my students regularly go on to earn 7s, the top grade. So I know the Diploma from the inside. Today I work online with IB students across Auckland, from Kristin and Rangitoto College to Diocesan School for Girls, and with families throughout the rest of New Zealand.

The IB Diploma maths courses

Which IB maths course is your child taking?

There are two IB maths subjects, each at two levels. I tutor all four — every lesson is built around the specific course and its exams.

AA HLHigher Level

Analysis & Approaches

The most demanding IB maths course — calculus-heavy, with a real emphasis on algebra and formal proof.

Best for: Engineering, physics, maths, economics at a top university

Calculus & differential equationsProof (incl. induction)Complex numbersVectorsHL Paper 3
AA SLStandard Level

Analysis & Approaches

A rigorous, largely non-calculator course built around algebra, functions and an introduction to calculus.

Best for: University study that needs solid, rigorous maths

Functions & algebraIntroductory calculusTrigonometryStatistics & probability
AI HLHigher Level

Applications & Interpretation

Applied and technology-active, with a strong statistics and modelling focus throughout.

Best for: Data science, business, social sciences, design

Statistics & hypothesis testingModellingGraph theoryCalculus for optimisationHL Paper 3
AI SLStandard Level

Applications & Interpretation

Practical, real-world maths with statistics and modelling at its heart, taught with technology.

Best for: A confident, real-world applied pathway through the Diploma

Descriptive statisticsFinancial mathsModelling with functionsGeometry & trigonometry
Where students really need help

The IA and HL Paper 3 — not just the exams

These are the parts of IB maths that trip up even strong students. They're also where focused help makes the biggest difference.

A strong foundation for the Exploration (IA)

The Internal Assessment is worth 20% of the final grade, and a strong Exploration rests on genuine mathematical understanding. That's exactly what our lessons build — so your child comes to their own investigation already confident with the mathematics behind it.

HL Paper 3

The extended problem-solving paper, unique to Higher Level, rewards mathematical thinking rather than memorised methods — long, unfamiliar, multi-part investigations. We practise exactly this style, so nothing on the day feels new.

Exam technique across every paper

Paper 1 (no calculator for AA), Paper 2 (calculator / GDC), and the HL papers — we work on setting out full method marks, using the graphics calculator well, and managing time under pressure.

Getting started

How it works

Simple, low-pressure, and built around your child.

1

Check you're set up

Lessons need a laptop, a tablet and stylus, and a reliable internet connection — so your child can handwrite maths naturally, right alongside me.

2

Get in touch

Tell me about your child through the Get Started form. Your first lesson is risk-free — if it's not the right fit, there's no charge.

3

A plan, then weekly lessons

I find their current level and set a plan, then we meet weekly online on an interactive whiteboard — with homework each lesson to lock it in.

4

Ongoing progress

Lessons run weekly through the term. You stay in the loop on how they're tracking, and we adapt as their confidence grows.

Founder & Lead Tutor
M.Sc. Mathematics, First-Class Hons (Auckland) · nearly 15 years' experience

My goal isn't just to get your child through the next test — it's to build strong foundations that set them up for the long term. I teach for understanding over memorising, keep lessons calm and encouraging, and tailor each student's path toward wherever they're heading, whether that's NCEA, Cambridge, IB, or beyond.

NCEA Level 1-3Cambridge AS & A LevelIBDP AA/AI HL & SLScholarship Calculus

I received my Masters Degree in Maths (First Class Honors) from the University of Auckland in 2014. With nearly 15 years of teaching experience, I have taught at many different schools across Auckland including Kristin School. I specialize in delivering highly effective online education and received the Ernest Duncan Award in 2018 for my contributions to the field. More than anything, I focus on building strong mathematical foundations for long-term growth — planning each student's learning with the end in mind. I strengthen the fundamentals first, then tailor their path toward whatever they choose next, whether that's NCEA, Cambridge, IB, or beyond. With the right foundations and a little foresight, students aren't just ready for their next exam — they're set up for the pathway that suits them best.

Jo

"We were so lucky to have Kenneth helping my daughter. Kenneth was a fantastic tutor who had great teaching skill and patience. Also Kenneth was very flexible to fit in my daughter's busy schedule. Thank you to Kenneth for helping my daughter to achieve great results on her exams."

Tarmindar

"Kenneth has been a brilliant tutor for my year 10 son. He develops rapport and teaches in a kind and fun way. He structures the lessons and gives my son time to return to aspects of the lesson. I recommend him - exceptional."

Ying

"他是非常负责而且教课特别清晰逻辑好的老师，我的儿子很喜欢他的课"

Shaheen

"Kenneth answers all my questions promptly and breaks down the concepts so that I can understand easily. I would recommend him to anyone."

David

"Mr. Clarkson has been an excellent tutor for my son. He is highly reliable, professional, and organised in his teaching approach. We have been very pleased to see clear improvement in my son's understanding and confidence in both math and physics. I highly recommend him as a tutor."

Michelle

"We engaged Kenneth at the 11th hour for our sons NCEA level 2 physics exam. Kenneth had two weeks to help get the student over the mark. Kenneth meet with the student every second day, was punctual, reliable and most of all our son enjoyed working with Kenneth and said 'If I had had Kenneth as my teacher this year I wouldn't need extra tutoring and I would understand this'. The exam was sat today and our son felt very prepared believed it went well. Thank you Kenneth, whatever the result of the exam, your tutoring was fantastic and we appreciated your commitment to the task at hand. We recommend Kenneth without hesitation."

Michelle

"Mr Clarkson's teaching has helped my daughter immensely with maths. Over the three years he has been teaching her she has gone from getting 3 or 4/8 in maths, to 7-8/8 in maths. We're really lucky to have him teaching our daughter and highly recommend his classes to anyone trying to improve their maths"

Lily

"I’ve been working with Mr. Clarkson for two terms, and his guidance has been incredibly helpful. He explains difficult concepts clearly, especially in calculus and physics, making them easier to understand. His support has definitely improved my confidence and understanding of the subjects. Highly recommend"

Lin

"老师很有水平，讲课深入浅出。孩子以前最怕函数，现在听了几节课后彻底开窍了。老师非常擅长把复杂的逻辑拆解开来，特别适合基础薄弱或者想打牢根基的学生。"

Cassandra

"Kenneth has been tutoring my daughter for her NCEA level 3 Calculus exam. He has been excellent and really helped her understand how to approach the more compiicated questions across the 3 topics so she could sit her exam with confidence. I would highly recommend Kenneth as a maths tutor."

Lara

"My son has really enjoyed being tutored by Mr. Clarkson. He has made real progress, feels more confident and has genuinely re-discovered his love for Maths again!"

Mike

"Kenneth has great credentials, and an amazing style with the students. He is a professional teacher and, unlike so many tutors who just help with homework and do their best to assist in 'understanding today's school lesson', Mr. Clarkson teaches. He ensures the foundations are in place and teaches with and ahead of the school maths curriculum, sets reinforcing homework, feeds the brain and teaches to grow as well as to understand and be better. As the highest endorsement we can give - after working with our Year 11 (15YO), he is now also teaching our 11 year old. And they both love it."

Weila

"Kenneth is a great maths teacher. Our 11 year old son really enjoys learning maths from Kenneth. Kenneth is patient, kind and professional. He could quickly find out my son’s level and built his learning objectives from there. He’s offering extra challenges while making maths studies fun. We are lucky to find Kenneth as our son’s maths teacher offering him extra learning to keep his passion for maths going further. Thank you Kenneth!"

Linda

"Highly recommend Kenneth! He has helped my 12 year old son in such a short amount of time. Very patient, identifys the struggle in my son, works well with my son. His teacher has seen a huge improvement and encourages us to continue with the tutor. So happy with Kenneth. Thank you."

Jessie

"“非常有耐心且充满正能量。孩子以前对数学没兴趣，但老师很会鼓励学生，课堂氛围轻松但不失严谨。现在孩子主动做题的积极性高了很多，数学不再是家里的难题了。”"

Naomi

"Kenneth was an amazing support for my daughter in the few weeks before her NCEA level 3 Calculus exam. She wanted to fine tune some areas that had challenged her in Mocks, and Kenneth made space to fit in quick tutoring sessions to give her a huge amount of confidence going into the exam. She said he was fantastic at explaining things, and felt very pleased with how the exam then went. Thanks Kenneth, would thoroughly recommend you."

Stana

"Kenneth provided a great tutoring online to our son Philip who was preparing for the maths Cambridge exam. Philip's experience with Kenneth - he explains everything very well so it is easy to understand, is patient, supportive, easy to relate to, and a great listener. Philip recommended him highly. His Cambridge results were what he hoped for. Would certainly work with Kenneth again if needed maths support later on at University, as not taking maths in his last year of High School. Kenneth was also accommodating with his schedule and managed to fit in a class on Sundays - we really appreciated that and felt lucky to have come across such a great tutor."

David

"Kenneth has been tutoring my son L3 calculus. He has a well thought-out system for teaching online which enables students to make the most of the sessions. During the lessons, he is well prepared and has the skills to diver deeper into particular areas of difficulty and pivot the learning accordingly. He has provided clear explanation of all topics. His communication is excellent, and he is always on time and invoices promptly. My son has really benefited from having Kenneth as a tutor and we would highly recommend him to others."

Nicole

"Lovely tutor for both maths and physics"

Andrea

"My daughter is enjoying her tutoring with Kenneth. He is knowledgeable and teaches the course material well."

Questions

IB maths tutoring — your questions

Yes — I tutor both IB Diploma maths subjects, at both Standard and Higher Level: AA SL, AA HL, AI SL and AI HL. Whichever route your child is on, the lessons are built around that specific course and its assessment.

The IA is a significant part of the course — worth 20% — and under IB rules it has to be the student's own independent work. What makes the biggest difference to it is genuine mathematical understanding, and that's where lessons focus: making sure the maths behind your child's Exploration is sound and truly their own. Strong fundamentals are the best preparation for a strong IA.

Yes. HL Paper 3 is the extended problem-solving paper unique to Higher Level, and it rewards mathematical thinking over memorised methods. We practise that exact style of long, unfamiliar, multi-part question so it feels familiar by exam day.

Happy to. In short: Analysis & Approaches is the more pure, calculus-and-proof route, and is usually the right choice for engineering, physics, maths or economics at university. Applications & Interpretation is applied and statistics-led, taught with technology throughout, and suits data science, business, social sciences and design. The right pick depends on your child's strengths and where they're heading — tell me about them and I'll give you an honest recommendation.

For almost all students, yes — and often better. We're on live video and both write on a shared interactive whiteboard in real time, so I can work a problem while your child solves alongside me, correcting their working as we go. Every board is saved as revision notes, there's no travel, and scheduling is easier. Most students say they'd never go back.

Earlier is easier, but any point in the Diploma works. Starting in the first year builds strong foundations and gets the IA off to a good start; starting in the second year, we focus on shoring up topics and sharpening exam and Paper 3 technique. Even a few focused lessons before the IA deadline or final exams make a real difference.

Yes — lessons follow the current IB Diploma Programme mathematics syllabus (the AA and AI courses), across all five topic areas: Number & Algebra, Functions, Geometry & Trigonometry, Statistics & Probability, and Calculus.

My main focus is the IB Diploma Programme (DP) — the AA and AI courses. I also help younger students in the Middle Years Programme (MYP) who are building toward the Diploma; get in touch with your child's year level and I'll let you know if I'm the right fit.

One-on-one tuition is $89 per lesson (currently $83 per lesson with the Term 3 Special), and small-group classes are $42 per lesson ($39 per lesson with the special).

Fill in the Get Started form below with a little about your child and their IB course. Your first lesson is risk-free, and I usually reply within 24 hours.
