I took this class with Kathryn Southall. It was completely asynchronous and at your own pace except for the midterm and final which had due dates. You use the software Caduceus which includes powerpoints that you click through on the information, and then a quiz based on the information. There is a practice quiz that you go through first which has all of the same questions, so you are basically guaranteed an A! The midterm and final also use all of the same questions from the practice quizzes throughout the year. Since you can do it totally at your own pace, you could totally finish this class in like 2 weeks. The midterm and final have due dates but are open all year long. Super easy one credit class!
