Cambridge Physics · 0625 · 9702

Physics, taught properly.

A teaching practice in the open, built by an educator with sixteen years across five countries: classroom teaching, coordination, teacher training, and education research. Cambridge-certified for IGCSE 0625 and A-Level 9702, with published research in cooperative learning and concept mapping.

Choose your path.

Students study by syllabus; teachers plan by topic. Both deserve materials designed for how they actually work.

Written by a practising teacher.

Everything here is built and reviewed by one teacher in one classroom, not assembled by a content team.

The Author

Rejo Raghuvaran

Physics Educator · Teacher Trainer · Education Researcher · Cambridge since 2017

Sixteen years in education internationally. My roles have spanned classroom physics teaching, academic coordination, assistant professorship at a teacher education college, teacher training, and research as a Junior Research Fellow at the University of Kerala. I have been teaching the Cambridge curriculum since 2017, delivering IGCSE Physics (0625) and AS / A-Level Physics (9702).

My academic foundation is in physics (MSc, Bharathidasan University) and science education (MEd, Mahatma Gandhi University). My published research focuses on cooperative learning strategies, particularly the Jigsaw-IV method, and on concept mapping as a tool for physics comprehension. That research quietly informs how this site is built.

Everything on this site comes out of work I actually do: lessons I plan for my own students, misconceptions I see weekly, the practical demos that finally make a concept click. The Teacher Portal is where I share what works.

What makes this different.

There are plenty of revision sites. This one is built around three commitments.

01

Visual first, formula second.

Every concept gets an intuitive diagram or thought experiment before the algebra. Physics is hard because the textbooks usually do it the other way around.

02

The examiner's mind, surfaced.

For every worked question, you'll see what an examiner is looking for, and what they're not. The hidden mark-scheme logic, made visible.

03

Teaching, backed by research.

The Teacher Portal draws on my own published research in cooperative learning strategies, surfacing the active-learning techniques (Jigsaw-IV, concept mapping) that actually work in a real Cambridge classroom. Free, and always will be.
