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.

Clean layout, accurate content and good questions. One or two questions felt easier than the real thing, so do not skip the harder scenario ones.
Studied in the evenings for ten days and passed. The glossary flashcards alone were worth the price.
Passed with 889 after about a week of evenings. The cloud concepts chapter explains high availability, scalability and elasticity with simple examples, and the practice questions after each section showed me exactly which topics I still had to revisit.
Every course is written and kept up to date by Kubilay Tarhan, who founded Brixus in Amsterdam to make studying something you do, not something you reread. Read the story .
Frequently Asked Questions
Can I try a course before I buy it?
Yes. Every course page has free sample questions you can answer without an account, and you can try one right here on this page. You only need an account when you buy.
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 the exam skills outline, then reviewed and corrected by hand before it is published. Courses are updated when the underlying exam or material changes.
Are these the real exam questions?
No. They are exam-style practice questions written against the official skills outline. Brixus is an independent publisher and is not affiliated with Microsoft or any other certification provider.
