This course was an excellent introduction to the stem cells and allowed me to develop the stem cell literacy quickly. The course is about 5-weeks long with deadlines for each module. That said, you can work ahead and finish the course as soon as you like (which I really appreciate!). Videos and resources are great for learning, and quizzes make sure that you're grasping information and demonstrating your knowledge. It was well organized and concise that it makes it easy to learn, play around, and spend more time on the various topics. I also would like to acknowledge that it gives you multiple tools to seek out/research extra information if you want to.
