Questions Parents Ask.

Most tuition is passive: the teacher explains and the student copies. In a review of 225 studies, students in lecture-style classes were 1.5 times more likely to fail than students who actively worked through problems. Our lessons keep asking your child to predict, answer and apply.

Re-reading feels productive but fades fast. Pulling an idea out of memory is what makes it stick: in one study, students who practised recall remembered about 80% a week later, against about 36% for those who re-studied. Every lesson ends with a knowledge check, and ideas come back for spaced revision.

Exams test recall, not recognition, so that is what we practise: questions after every lesson, practice sets at three levels, and past-paper questions with a timed option. Recalling under pressure becomes a habit.

People learn best in the zone between too easy and too hard, which the psychologist Lev Vygotsky called the zone of proximal development. A class pitched at the average misses both ends. In our live sessions, experts ask questions to find where your child really stands, and practice comes in three levels.

A bit of struggle helps memory, as long as help is at hand. In one study, students who practised mixed problem types scored 63% on a test a week later, against 20% for those who practised one type at a time. Hard questions come with worked examples, hints and a reason for every wrong answer.

In 11 out of 11 experiments, students learned more from words with pictures than from words alone. We show the real thing first, then the diagram, and each scene shows only what is being explained.

Every lesson is interactive. Videos stop to ask questions, study guides include games, and every lesson ends with a knowledge check. Enrolled students also get weekly live sessions and a moderated community, and parents get progress reports.

It is our own way of teaching science, built on four research-backed pillars: Structural Visualisation, Cognitive Synthesis, Strategic Retrieval and Institutional Support. See the Science of Learning page.

We would rather show you than claim it, so here is what every student gets. Compare it with any class you are considering. Our teaching is built on some of the best-evidenced methods in learning science: a major review of 10 study techniques rated only two as “high utility”, practice testing and spaced practice, and we use both. It also draws on research published in the journals Science and PNAS. Every lesson is interactive, no lesson video runs over 12 minutes, and every video has English captions. Practice goes up to Olympiad level. Every week, subject experts run Socratic live sessions, and parents get a monthly progress report. Try it free for 5 days.

Every week, enrolled students meet The Collective, our global faculty of subject experts. Sessions are Socratic: experts ask questions to find where each student's understanding really stands, then teach from there.

Our moderated community lets students solve problems together, with subject experts on hand.

You get a progress report every month, and we contact you early if your child seems to be slipping and may need support.

The Collective, our faculty of subject experts, led by Dr Susnata Karmakar, Founder and Academic Director. Meet the team.
