How many tests should one take before AWS certification?

Hello Dwit, Our assessments are there to verify you have absorbed the knowledge from the courses and hands-on labs. If you are regularly achieving a percentage of high 80's - 90's in the assessments then you are doing great! If however, you are scoring 50%- 80% then we recommend repeating the assessments and understanding where your weak points are allowing you to review the relevant content to help you increase your score. When you are confident you are hitting those higher scores then you will be better prepared to take the certification. Should you need further assistance, feel free to reach out to support@cloudacademy.com. Thank you!
