The courses

Pick your exam. We’ll do the rest.

Every course is written in full before it goes live.

For children aged 5–11

Learning that feels like play.

Animated lessons that read themselves aloud, games full of stars, and a cheerful buddy called Budlet who never says “wrong”.

Hi, I’m Budlet! Let’s learn together.

  • Lessons that talk

  • Stuck? It tries another way

    When a topic is tricky, Budlet teaches it again a different way, then practises with your child until it clicks.

  • Stars, never “wrong”

    Stars and kind words for effort. A slip gets “Not yet”, a look at why and another go, and stars are never taken away.

  • Safe by design

    No ads, chat or videos, and nothing made up by AI on the spot: every lesson and question is prepared and checked in advance. We never ask for a child’s name.

  • A grown-ups area

    Behind a grown-ups lock: progress on every topic, what needs a hand, and the settings.

Pricing

Questions

Asked often.

Each exam page answers its own questions too.

Which exams does Courselo cover?

Complete courses in English proficiency, admissions tests, school qualifications, national exams, IT certifications, professional qualifications and primary school, including the IELTS, SAT, GCSE Maths and ACT. A course is listed only once it is complete, with a lesson for every topic and all of its strategy guides and mock exams written. New courses appear here as soon as they are finished.

What can I do for free?

Read the first lesson and strategy guide of every course in full, and the first part of every other lesson and guide. Answer 10 practice questions a day, take the diagnostic test for every exam, and send the AI tutor 3 messages a day. Pro unlocks every lesson and guide and removes every limit, adding full mock exams and AI marking of essays and speaking.

How is my predicted score worked out?

From your mastery of each topic, weighted by that topic’s share of the real exam and run through the same scoring curves as a full mock. It is always shown as a range, and the range narrows as you answer more questions.

Is Courselo affiliated with the exam boards?

No. Courselo is independent. Each course follows the published specification, and every exam page says when its format and scoring were last checked against official sources.

What do the “AI-drafted” and “AI-generated” labels mean?

A lesson or guide marked “AI-generated · reviewed” was written with AI from the exam’s official specification. A course marked “AI-drafted course · format verified” also had its outline (sections, syllabus and mock plans) drafted with AI, from the exam’s officially verified format. Either way, every lesson, guide and mock is written and checked before the course is listed, and new practice questions are written as you practise. Each item is validated against the course structure and checked for correctness before it is shown, then kept so every learner sees the same material. Pages written entirely by our team don’t carry a label.

Can I cancel Pro at any time?

Yes. Manage or cancel your subscription from the billing portal in your account. Your progress stays with you on the free plan.
