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. Focus on heavily-weighted domains first. Domains with higher percentages appear more on the exam. Master these before moving to lower-weighted areas.

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.
