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.
Study in short, spaced sessions: a card you have not seen for two days is worth more than a card you reread immediately. Filter by Value Streams first, then mix domains so you practise identifying the topic before recalling the definition.
They are the recall half of preparation. Pair the cards with practice questions and at least one timed practice exam — candidates who only review cards usually recognise terms but miss scenario questions.
