You studied for weeks. You read every whitepaper AWS published. Then you sat a mock exam and scored 58%. Sound familiar?

You have gone through all the tutorials. You have created several clusters. And yet you do not feel prepared.

You have finished reading the text. You have already completed the course. You've told your manager that you are "basically ready." But until exam day, no one asks the uncomfortable question: Are you actually ready, or do you just feel ready?
