• Week 8: Domain 5: Post-exploitation — Windows/Linux privilege escalation techniques
• Week 9: Domain 5: Pivoting — Lateral movement, port forwarding, tunneling, AD attacks
• Week 10: Domain 6: Reporting — Report writing, risk ratings, remediation recommendations
• Week 11: Index Building: Create open-book index for exam day, organize notes by topic
• Week 12: Full Review: Practice exams, Index refinement, Weak areas, Exam logistics

Top Study Tips

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