Online IB Tutor

Looking for an expert online IB tutor? I offer flexible, high-quality online IB lessons for students anywhere in the world. With a PhD in Physics, 10+ years of IB tutoring experience, and 200+ five-star reviews, every lesson is one to one and built on real past papers.

How Online IB Tutoring Works

My online lessons are interactive and structured, using shared whiteboards, screen sharing, and real-time problem solving. Each session is tailored to your specific needs — whether it's exam preparation, Internal Assessment guidance, or building foundational understanding.

Flexible scheduling across time zones
Interactive whiteboard and screen sharing
Whiteboard and lesson summaries kept for revision
Full attention, one to one, for the whole hour

When results don’t move, more practice is rarely the answer.

Something specific is costing the marks, and until it is named, extra hours only repeat it. In my experience, the cause usually falls into six areas, often in combination.

Conceptual gaps
Problem solving
Exam technique
Time management
Reading the question
Gaps from earlier years

Does this sound familiar?

Do you recognise your child?

Works hard, but the grade doesn’t move.

The hours go into what already works.

Understands in class, loses it in the exam.

Exam performance is a separate skill, and it was never trained.

Has lost confidence in the subject.

Anxiety now costs more marks than the subject does.

Already strong, aiming for a 7 at HL.

The last boundary is decided by the hardest questions and the IA.

What is usually happening, and what changes

The approach

Diagnosis before repetition.

1
Assess
A real official past paper, worked through while I watch how the student thinks.
2
Diagnose
Conceptual, technical and exam-performance problems, separated.
3
Rebuild
Work on the areas with the greatest impact, on real papers.
4
Measure
Timed papers against the baseline. Progress measured, not assumed.
