Google Cloud AI study guides
Interactive study guides for Google Cloud AI and machine learning certifications, with labs, calculators, sample outputs, scenarios, flashcards and practice quizzes.
Professional Machine Learning Engineer (PMLE)
Follows the exam guide dated June 1, 2026. Exam sections: low-code AI ~13%, data and models across teams ~16%, scaling prototypes ~21%, serving and scaling ~20%, pipelines ~18%, monitoring ~13%. Vertex AI is now Gemini Enterprise Agent Platform; the guides use the new names and map them to the old ones. Stars show how much exam weight a guide carries (★★★ heaviest).
Suggested study path
- Exam overview to see the scope and the renames.
- The two ML fundamentals guides: most scenario questions hinge on leakage, imbalance, overfitting and choosing the right metric.
- The three gen AI guides: Model Garden, Agent Platform, RAG failure modes and LLM evaluation.
- The six exam-section guides, in order, for the Google Cloud product choices.
- Retake each guide's quiz until you score above 85%, then review its gotchas list the day before the exam.
