Study notes and exam details

• Reference: English exam guide updated October 15, 2026. The guide does not state a separate skills-effective date or numeric edition; numeric coverage IDs are editorial.
• The current credential page publishes 120 minutes and possible interactive components. Practice uses choice questions and does not simulate labs or interactive tasks.
• 50 questions is an internal practice default; no AI-300-specific count is published on the retrieved pages. Prices depend on the proctored country or region.
• The official passing score is 700 (scaled score).
• The guide includes embedding model selection and fine-tuning. Customization support varies by model and hosting option; this is not a claim that Azure OpenAI text-embedding deployments support fine-tuning. Re-embed the corpus when changing its representation and validate retrieval.
