Free self-paced course · No exam board

Understand AI — a free course in 15 topics

How these systems actually work, why they get things wrong, how to use them well and honestly, and how to stay safe when other people use them badly.

Written for secondary students and adults alike — including teachers, parents and anyone meeting these tools at work. No prior knowledge of computing or maths is assumed, and it is not tied to any exam board, so you can work through it on its own.

How the course works

1. Read the notes

Each topic has full written notes — key terms, worked examples with mark allocations, common mistakes, and a revision summary. Free to read, no account needed.

2. Answer 40 questions

Then test yourself on that topic. Every question explains its answer, so a wrong one teaches you something rather than just marking you down.

3. Move to the next

Topics build on each other, so work forward in order. Nothing is timed and nothing expires — come back whenever you want.

Who this is for

Secondary students

Written at the level of the other courses on Kramizo, with worked examples and mark allocations. Useful alongside any syllabus, and the only place most students will meet this material.

Adults

Nothing here assumes school. If you are meeting these tools at work and want to know what they actually do, where they fail and what you should not put into them, start at topic 1 like everyone else.

Teachers and parents

Readable as a whole, or topic by topic. The last three topics cover online safety, name real reporting routes, and are written for a young person to read alone.

The topics on online safety discuss grooming, fabricated sexual images, blackmail and harassment. They are written plainly and without detail that would help anybody do harm, and they point to named helplines and to the safeguarding staff every school has. Nothing in the course is legal advice.

Questions

Who is this AI literacy course for?

Anyone who wants to understand AI properly rather than just use it. It is written for secondary school students and for adults — including teachers, parents and people meeting these tools at work. No prior knowledge of computing or maths is assumed.

Does it cost anything?

No. All 15 topics of written notes are free to read without an account, and the practice questions are free to answer.

Is it tied to an exam board?

No. There is no exam board qualification in AI literacy, which is part of why we wrote it. It is a standalone course, so you can work through it alongside any syllabus or on its own.

How long does it take?

It is self-paced. Reading one topic and working through its 40 questions takes most people around 45 minutes to an hour, so the full course is roughly 12 hours spread over as long as you like.

Do I have to do the topics in order?

The order is deliberate — later topics build on earlier ones — so working through from topic 1 is the best way. But each topic also stands on its own if you only need one.

Does it cover online safety?

Yes. The last three topics cover people using AI to deceive and befriend others online, fabricated images and impersonation, and AI features inside everyday apps. They name real helplines and reporting routes, and they are written to be read by a young person on their own.
