FAQs:

1. Which video courses do I need to take?
   If you are like me and have completed the other two associate certifications, then I recommend completing Stephane's course.

2. How long does it take to prepare?
   It took me about 6 months as I prepared in conjunction with Solution Architect Professional.

3. What happens if I don't pass the practice exams?
   Try to score close to 70% in any practice exam in your first attempt. Don't be worried if you don't pass on your first attempt.

4. What do I do if I discover that I still have some weak areas after doing the practice exams?
   During the practice exams, if you find any areas that you seem to be weak in, then read more about those particular services in the AWS documentation.

3. Exam Tips

1. During the exam, I marked the questions I was unsure of for review. At the end of the exam, I had about 15 questions for review, which made me feel slightly confident that I might pass the exam.

2. Make sure that you don't leave any questions unanswered as there is no negative marking.

3. DO NOT attempt to answer the questions based on key words alone, ensure you read all the answers as well.

4. If English is your second language, you can request for ESL+30 mins before booking the exam from certmetrics > Request Exam Accomodations and wait for the approval. It might take a couple of days for the approval to come through.
