About CodingMarble Learn

A free study library where every topic comes with a 3D animation, a plain explanation and questions to practise.

What you will find here

Lessons are arranged in two ways. You can browse by subject, such as maths, physics, chemistry, biology, accountancy, economics, geography or fine arts, and read a topic on its own. Or you can browse by country and class, such as CBSE in India, Ontario in Canada, Germany, England, Korea and others, and follow the syllabus you actually study.

How a lesson is built

Each lesson opens with a short 3D scene that you can turn, zoom and change. A few story steps then explain one idea at a time, each with a plain caption, so the idea makes sense even with the sound off. After that come the written notes, worked examples, common mistakes, a quick quiz and a larger set of practice questions with hints and full solutions. Many lessons also have a recorded voice in English or Hindi.

Who it is for

Students who want to understand a topic rather than memorise it, parents who are helping with homework, and teachers looking for a clear explanation to show in class. The lessons are written for school and early college level.

What it costs

Nothing. You do not need an account, and you can read as much as you like. The site is paid for by advertising, which is why you may see ads next to the notes. Ads are marked, kept away from the 3D scenes, quizzes and practice questions, and never cover the text.

Who makes it

CodingMarble is a small independent team in India. We also run free online tools for PDFs, images, calculators, QR codes, typing practice, yoga and workouts. You can reach us at support@codingmarble.com.

A note on accuracy

We check each lesson before it is published, but syllabuses change and mistakes can slip through. Before an exam, always compare with your own textbook and your board's official syllabus. If you find an error, write to us and we will correct it.
