How Learning on Brixus Works
Rereading feels productive but fades fast. Every Brixus course is built around answering instead.
Mistakes come back first
Practice sessions bring back the questions you got wrong until you get them right, so your time goes where it is needed.
Flashcards that space themselves
Key terms become spaced-repetition flashcards, shown again just before you would forget them.
Progress per chapter
See which chapters you have mastered and which still need work, so you always know what to study next.

Frequently Asked Questions
Can I try a course before I buy it?
Yes. Every course page offers a free sample, and you can try a question right here on this page. A free account lets you read the first pages and start practice sessions. You only pay to unlock the full book.
What do I get when I buy a course?
The whole course: every chapter with its embedded questions, practice sessions that bring your mistakes back first, flashcards for the key terms, and your progress per chapter.
Is it a subscription?
No. You pay once per course and there is no subscription. Prices are shown on each course page, and VAT is calculated at checkout.
How long do I keep access?
There is no time limit: a course you buy stays in your library for as long as it is available on Brixus.
Does it work on my phone?
Yes. Courses work in any modern browser on your phone, tablet or computer, and in the Brixus Android app, with layouts made for small screens.
How are the courses made and kept current?
Each course is drafted with the help of AI from the official sources, such as an exam’s skills outline or the CEFR level descriptions, then reviewed and corrected by hand before it is published. Courses are updated when the underlying exam or material changes.
