ConceptOrbit is nearly ready.
We’re finishing the last lessons and simulations now. Everyone on the waiting list gets an email the day we open.

Try a real simulation
Revision guides tell you what happens; a simulation shows you why. Every ConceptOrbit simulation asks for your prediction first, then sets you tasks and checks your result. It’s the physics, maths or code itself, not an animation of it.
Free to try here, with no account.

Tasks0 of 3 done
Demo tools
Every course comes with calculators and tracers to open beside your homework. Here are three of them, working.
y = x² − 2x − 3
Interactive past papers
Every part has its own answer box and is marked against the mark scheme the moment you check it. Practise part by part, or sit a whole paper against the clock.
A shop sells notebooks for $2.40 each.
Work out the cost of 15 notebooks.
[1]In a sale, the price of a notebook is reduced by 15%. Work out the sale price of one notebook.
[2]Amir pays $30.60 for some notebooks at the sale price. How many notebooks does he buy?
[1]The questions on this page are exam-style, written for it in the format of Cambridge IGCSE papers.
Three courses at launch
Every lesson is free to read. Simulations, interactive past papers, mastery and the AI Tutor come with a course.
Motion to space physics, plus practical skills, with experiments you run yourself.
Simulations include
Number to statistics, Core and Extended, with the working a mark scheme wants.
Simulations include
Data representation to databases and logic, with pseudocode you can trace.
Simulations include
More subjects and qualifications will follow after launch: more IGCSE subjects, O Level, AS & A Level, and other exam boards such as Pearson Edexcel.
The same four steps in every course, so you always know where you are and what comes next.
Learn it
A short lesson in plain English, written to the syllabus. Free for everyone.
Experiment
Predict first, then change the variable in a simulation and see if you were right.
Practise it
Marked questions, and interactive past papers marked against their mark schemes.
Know it’s secure
Your mastery updates from marked work, so your revision goes where it’s needed.
For teachers
Your students learn from the same lessons you teach from. You open simulations and interactive past papers as you reach each topic, set work, and see who needs help while there’s still time to help.

Moments: 3 of 6 students are still emerging. Open “Balance the beam” for the class, or set a short quiz on it.
Gone quiet: Hamza R. has had no marked work for 12 days.
Students join with a seven-character code or an email invitation, and you let each one in.
Choose which simulations and interactive past papers your class can open, topic by topic. Every lesson is free already.
Quizzes, assignments, exams and study tasks with deadlines. Mark them yourself, or let AI mark first and approve each result before it’s released.
Every student against every topic, weakest first, and who has gone quiet since their last marked work.
Present mode puts a simulation on the classroom screen, and many come with notes on running them with a class.
Joining your class opens the course’s study tools for them, and they pay nothing.

ConceptOrbit is an online learning platform for Cambridge IGCSE Physics (0625), Mathematics (0580) and Computer Science (0478), with free lessons written to the syllabus, simulations, past papers marked against the mark scheme, and an AI Tutor. It opens soon with those three courses, and more subjects and qualifications will follow. The simulations and tools on this page are working pieces of it.
Yes, for learning. Every lesson in all three courses is free to read, with its practice questions, the course tools and a free simulation in every unit. Every simulation, all the interactive past papers and the AI Tutor come with the Student plan, from $8 a month, or with a teacher’s class.
At launch, Cambridge IGCSE Physics (0625), Mathematics (0580) and Computer Science (0478). Physics and Mathematics cover Core and Extended, and Computer Science has a single tier. O Level students will find most topics overlap, but we don’t claim the syllabuses are identical.
Yes. ConceptOrbit opens with three Cambridge IGCSE courses: Physics, Mathematics and Computer Science. More subjects and qualifications will follow after launch: more IGCSE subjects, O Level, AS & A Level, and other exam boards such as Pearson Edexcel.
No. ConceptOrbit is independent, and it isn’t affiliated with or endorsed by Cambridge University Press & Assessment. Its lessons follow the Cambridge IGCSE syllabuses, and the past-paper questions on this site are original exam-style questions.
Yes. Lessons, simulations and past papers work in a phone’s browser, and the simulations respond to touch. There’s nothing to install.
Most past-paper websites give you a paper and its mark scheme to read. ConceptOrbit marks each part on screen against the mark scheme, shows where marks are usually lost, and gathers every question on a topic into interactive topical past papers.
No. A teacher sees their students’ marked work and progress by topic, never what a student asks the AI Tutor. Only the student can read their conversations.
Soon. We’re finishing the last lessons and simulations now, and everyone on the waiting list gets an email the day we open.
The first 50 people to confirm their email address get 50% off, and the next 50 get 25% off. The discount is saved to your account and taken off when you choose a plan.
Places are numbered in the order people confirm their email, and we keep them private while the list is open. When ConceptOrbit opens, we’ll email everyone who earned a discount, and it will already be on their account.
No. You need an email address and a password, nothing else. There is no card to enter.
Every lesson stays free. The Student plan is $8 a month for your first course and $5 for each extra one, and a Class is $30 a month for 20 students. A place on the waiting list takes your launch discount off those prices.
No. Your class gives them progress, a study planner and the AI Tutor (7 questions a day, 70 a month) for that course, plus interactive topical past papers and the simulations and interactive past papers you open for them. Buying the course themselves opens everything in it.
Only if you choose. For each assessment you pick who marks it: you, AI with your approval, or AI on its own. With AI and your approval, nothing is released until you approve it.
They’re optional. Only the team building ConceptOrbit reads them, to decide what to build first.
The simulations and tools on this page are working pieces of it. If you tick “I’d like to test new features” after you sign up, we may invite you to try more before launch.
