Exam Structure: What to Expect 📚
Let’s break down the exam structure so you know exactly what you’re getting into:
- Total Questions: The exam contains 65 questions in total.
- Scored Questions: 50 of these questions will count towards your final score.
- Unscored Questions: 15 questions are unscored and used by AWS to evaluate potential future questions. These are not identified, so treat every question as if it counts!
- Question Types: Be prepared for various formats, including:
- Multiple choice: One correct answer out of four options
- Multiple response: Two or more correct answers out of five or more options
- Time Management: While the exam guide doesn’t specify a time limit, typically AWS practitioner-level exams allow 90-120 minutes. Pace yourself accordingly!
- Passing Score: The minimum passing score is 700 out of 1000.
Exam Strategy: Tips for Success 📝
- Answer Every Question: There’s no penalty for guessing, so don’t leave any questions unanswered.
- Time Management: With 65 total questions, pace yourself to ensure you have time for all sections.
- Read Carefully: Pay attention to the wording in questions and answers. Look for key phrases that might change the meaning.
- Process of Elimination: If unsure, try to eliminate obviously incorrect answers to improve your chances.
- Flag for Review: If you’re unsure about a question, flag it and come back later if time allows.
- Stay Calm: Remember, you only need to pass. It’s okay if you don’t know every single answer.
Final Thoughts: Embrace the Challenge! 💪
Remember, this certification journey is as much about learning as it is about the credential. Embrace the challenge, stay curious, and you’ll not only pass the exam but also gain valuable skills for the AI-driven future!
