Experienced online tutor of the IB and IGCSE curricula specialising in Biology, Chemistry, Mathematics and Physics. I have good tutor reviews and hold a Graduate Diploma in Educational Studies.

About

I have several years of experience tutoring students with a focus on both academic excellence and learner confidence. I tailor each lesson to the student’s specific academic needs, learning style, and long-term goals.

As an educator, I combine structured lesson planning with flexibility to respond to a student’s evolving understanding. I often use scaffolded questioning, real-world examples, and visual or interactive tools to support comprehension—especially for abstract or complex concepts.

For online tutoring, I integrate screen-sharing, virtual whiteboards, and collaborative documents to create a dynamic and engaging learning experience.

Five stars are not enough — Timothy is the tutor every desperate parent dreams of finding
We found Timothy at what I can only describe as our lowest point. My son was sitting on a 3/10 in Science Double Award and a 4/10 in maths, and the school had handed him four resit exams to prepare in just two months. The situation felt hopeless — we were out of time, out of options, and honestly out of hope.
Then Timothy stepped in, and everything changed.
He worked with my son all summer, covering biology, chemistry, physics and maths. But calling it "tutoring" doesn't do it justice. Timothy is the kind of teacher who doesn't just transfer knowledge — he rebuilds confidence from the ground up. He has this rare gift for making a discouraged student believe in himself again. Patient, encouraging, endlessly patient (yes, it's worth saying twice), he knew exactly when to push and when to lift my son back up. A real-life superhero, minus the cape.
The results speak for themselves: my son not only passed all four resit exams — he scored 8/10 on his very first chemistry test after working with Timothy. From a 3 to an 8.
I recommend Timothy without a single reservation. If your child is struggling, overwhelmed, or has lost faith in their own abilities, Timothy is not just a tutor — he is the turning point. We will be forever grateful.

Teaching methods

My teaching style is adaptive, student-centred, and grounded in both empathy and structure. I believe that every learner brings a unique set of strengths, experiences, and challenges to the table, so I aim to meet them where they are — academically and emotionally — and support them in reaching their full potential.

I primarily use a scaffolded approach: I start by breaking down complex concepts into manageable parts, use clear examples to build understanding, and gradually release responsibility to the student as their confidence grows. For skills-based learning, I often use the PPP method (Present, Practise, Produce) or a guided inquiry approach, depending on the learner’s needs. I also integrate questioning techniques that promote critical thinking and reflection, encouraging students not just to get the right answer, but to explain their reasoning and understand the “why” behind it.
