This practice quiz is required. Please be diligent in your camera setup for this practice. Follow all testing protocols including the room scan. This should be treated as if you are taking a real exam. Your video will be reviewed by the instructor and feedback provided. It is critical that you are actively monitoring your ACC email for feedback and correspondence. You will be prohibited access to the first exam if your testing environment does not meet protocol or you fail to complete this assignment on time. The exam deadline will not be extended and you will receive a zero. After approval or at any time during the semester you fail to follow protocol, you will be locked out of exams or given an automatic zero (see syllabus). Repeated violations will result in course failure.
