• Week 11: Solution and operations excellence: Deployment and Support (Blue-green deployments, canary releases, support cases)
• Week 12: Full Review: Case studies, Architecture diagrams, Practice exams, Weak areas

Top Study Tips

1. Start with the official exam objectives. Download them from the Google Cloud website and use them as your study checklist. Every exam question maps to a specific objective.

1. Use active recall over passive reading. Instead of re-reading notes, test yourself with practice questions after each study session. This dramatically improves retention.

1. Check the official exam guide for section weights first. Put the most study time into the sections that carry the most exam weight, then cover the rest.

1. Build hands-on experience. Set up a lab environment and practice the skills you are studying. Hands-on experience is especially valuable for performance-based questions.

1. Take practice exams under real conditions. Time yourself, eliminate distractions, and simulate the exam environment. Review every wrong answer and understand why it was wrong.
