They cover all 9 domains of the OGBA-101 exam: Value Streams (17.5%), Introduction and Concepts (15%), Business Capabilities (15%), Introduction to the ADM (12.5%), Business Modeling (10%), TOGAF Business Scenarios (7.5%), Information Mapping (7.5%), Organization Mapping (7.5%), Applying Business Architecture Techniques within the TOGAF ADM (7.5%). Each section is weighted in the same proportion as the real exam, so nothing high-value is buried.
The OGBA-101 exam has approximately 40 questions in 60 minutes, with a passing score of 60%. Use the practice questions to confirm you are consistently above that line before booking the real exam.
Read a domain, then immediately answer practice questions on it — recall is what moves knowledge into long-term memory. Start with Value Streams, and finish with a mixed set so you practise switching between topics.
They cover the content, but reading alone is not enough. Answer practice questions for every domain and take a timed practice exam; the notes are most useful when you return to them after a wrong answer.
