Practice modes

  • Timed mock exams: build pacing, endurance, and decision-making under time pressure.
  • Topic drills: fix weak areas fast (best for spaced repetition).
  • Mixed review: combine recent misses with high-yield topics to reinforce retention.
  1. Skim the syllabus and mark high-weight topics.
  2. Drill one topic at a time (untimed first, then timed).
  3. Review explanations immediately and keep a short miss log.
  4. Run a timed mock to measure pacing and coverage.
  5. Re-drill weak sections, then retake a fresh mixed set or mock.

Timing tip

  • Use untimed sets for learning and timed sets for performance.
  • If you keep running out of time, reduce re-reading and aim for a first-pass answer, then review flagged items.

What to pair with practice

  • Overview: what is tested and how to approach questions -> read
  • Syllabus: objectives by topic/domain -> open
  • Cheatsheet: high-yield formulas, tables, and decision pickers -> review
  • Study plan: a simple 30/60/90-day path -> use
  • FAQ: common candidate questions -> see
  • Resources: official references and exam pages -> browse

Tip: The fastest way to improve is to turn every miss into a one-sentence rule and re-drill that topic 48-72 hours later.

Generative AI Professional is a “production judgment” exam. You’re tested on building GenAI systems that are grounded, safe, and operable.

What you should be able to do

  • Choose between prompting, RAG, and fine-tuning based on constraints.
  • Design retrieval: chunking, embeddings, metadata filtering, and top‑k selection.
  • Evaluate GenAI systems beyond “it sounds good”: groundedness, relevance, and safety.
  • Defend against prompt injection and data leakage.
  • Operate deployments: monitoring, rollback, and cost/latency control.
  • Understand OCI’s GenAI and Data Science service areas at a conceptual level.

How to prepare efficiently

  1. Use the Syllabus as your checklist.
  2. Practice scenario reasoning (why each wrong choice fails safety/ops).
  3. Use the Cheatsheet for last-week pickers and templates.
