A subject map, not a maze
Know where you are in a subject
Biology, exam readiness, writing, STEM, computer science, languages, and study planning each follow a sequence you can actually see — what leads into what, and where you are on it. Anything still being built is labelled as such, so you always know what you are clicking into.

Coming soon
A tutor that explains, not one that just answers
Stuck at 11pm the night before? Academy's tutor will walk you through the how and the why, then check that you can do the next one yourself. We would rather open it late than open it half-built, so it stays closed until it is genuinely good — and it will never invent an answer to look clever.

Study alongside other people, without the noise
Quiet rooms with a shared timer, so the long hours feel less lonely — the accountability of working together without a group chat going off every ninety seconds. Rooms open once we can keep them genuinely safe and calm, and not before.
See what's comingCourses with a beginning and an end
Each one is a sequence you work through in order, built from activities you can open right now. You always know what you are learning next, and why.
- Physics and engineeringCircuits from scratchBy the end you can read a circuit diagram, predict what a change will do before you build it, and explain why a series branch and a parallel branch behave differently.Start the course →
- MathematicsAlgebra you can trustBy the end you can solve linear equations, inequalities and pairs of simultaneous equations without guessing — and say why every step you took was allowed.Start the course →
- Logic and reasoningThinking straightBy the end you can take an argument apart, name exactly what is wrong with it, and build one of your own that holds up.Start the course →
- StatisticsRead the dataBy the end you can summarise a set of data honestly, say what it does and does not show, and spot a chart that is lying to you.Start the course →
- Computer scienceDebug itBy the end you can read code you did not write, find the bug in it, and explain why it was a bug.Start the course →

Built to be trusted — and straight with you about what it is

Built for a real schedule
Activities sized for the gaps in your day — between classes, on the bus, after practice.
A study aid, not a substitute
Academy strengthens your coursework and test prep. It is independent, and not affiliated with any official testing authority.

You can see what is ready, what is coming, and what makes sense to do next — no hunting.
One Koydo, all the way up
Academy is the 14–18 tier of a learning ladder that starts at age two. Looking for a different age band? Each tier has its own Koydo.
Questions, answered
Who is Koydo for?
Students roughly 14 to 18 — high-school age — who want study tools that treat them as capable, and are straight with them about what is finished and what is coming.
What can I actually do in Academy?
Browse hundreds of interactive activities across every subject and work through Academy's subject map. Lessons, scored practice, flashcards, saved progress, tutoring and study rooms are on the way, and each is labelled so you know what you are opening.
Is scored Academy practice available?
Not yet — it is coming. We would rather hold it back than hand you a score you cannot trust. The activity library is open now and does not depend on it.
What does ‘coming soon’ mean here?
It means we are building it and it is not open yet. We label it rather than dress it up as finished, so nothing on Academy surprises you.
Where should I start today?
Open Explore and pick an activity, or open Subjects to see the map and choose a direction.
Is Academy affiliated with an official exam board?
No. Academy is an independent study aid built by Koydo. It is designed to strengthen your coursework and test preparation, not to replace your school or any official testing authority.
Start where you are
Open something today. Build from there.
Start with an activity that fits this afternoon, then use the subject map to see what naturally comes next. More is on the way — saved progress, scored practice, the tutor, study rooms — and you will see each one arrive rather than being sold it early.
