I took a quiz and ran out of time. Is there any way to retake the quiz?

I'm pretty sure that the answer is no, but don't fret. The quizzes are to prepare you for the final certification exam. As long as you understand what you did answer, you should be fine. If you have questions about anything on the quiz, please go to the summer of learning section of the forum. We won't want to discuss specific questions, but we can certainly discuss the concepts.
