• Week 5: Domain 3: CI/CD Pipelines — CodeCommit, CodeBuild, CodeDeploy, CodePipeline, deployment strategies
• Week 6: Domain 3: SAM & CloudFormation — SAM templates, sam build/deploy, Elastic Beanstalk, containers
• Week 7: Domain 4: Observability — X-Ray tracing, CloudWatch Logs/Metrics, Lambda Insights, debugging
• Week 8: Full Review: Practice exams, Hands-on labs, Weak areas, Exam logistics

Top Study Tips

1. Start with the official exam objectives. Download them from the AWS 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.
