📝 Exam Strategy i Test-Taking Tips

Strategic Exam Preparation

EXAM PREPARATION STRATEGY:

PHASE 1: KNOWLEDGE CONSOLIDATION (2 weeks before exam)
□ Review all hands-on labs completed during course
□ Practice jeden lab z każdego domain daily
□ Create summary notes dla each service i use case
□ Identify weak areas i focus additional study

PHASE 2: PRACTICE TESTING (1 week before exam)  
□ Take full-length practice exams daily
□ Time management practice (2.5 minutes per question average)
□ Review incorrect answers i understand reasoning
□ Focus na scenario-based questions (highest difficulty)

PHASE 3: FINAL PREPARATION (3 days before exam)
□ Light review of key concepts only
□ Practice exam timing i breaks
□ Prepare physical/mental state dla exam day
□ Review exam policies i requirements

TEST-TAKING STRATEGIES:

DURING EXAM:
1. READ CAREFULLY: Pay attention do keywords like "must", "least", "most appropriate"
2. ELIMINATE WRONG ANSWERS: Rule out obviously incorrect options first
