Hi Leigh Anne,
Good question!
Yes, you could do that, but there are a couple of things to keep in mind.
1.The only score we can see on our dashboard is the most recent one you’ve taken. So, if you accidentally scored lower on your second attempt, we would no longer see your first score. You can prevent this from interfering with earning Certification by archiving all of your emails with your quiz scores, so if you needed to, you could forward proof to me that you had a higher score on a first attempt.
2. We encourage you to understand the correct answers to as many of the quiz questions as possible before moving on in the course, both for the sake of the knowledge itself, but also to increase your chances of passing the Module Exam. Sometimes you can glance at a quiz result and realize what the correct answer is, without needing to retake it. But sometimes retaking the quiz is going to be more effective.
Hope that helps! Let me know if you have any other questions.
