Where to Focus Your Study Time
Domains with higher weight have more exam questions — allocate your study hours accordingly.
Study Tips
- Create a 14-week study schedule and assign specific domains to each week
- Focus more time on higher-weighted domains — they have more exam questions
- Use practice quizzes to identify weak areas early, then revisit those domains
- Study in focused 25-minute blocks (Pomodoro technique) with 5-minute breaks
- Create flashcards for key terms, acronyms, and port numbers
- Review domain objectives weekly to track your progress and adjust your plan
