I've just signed up for it lol ! Am I crazy - not sure how I am going to do it. But great that it is free and I might surprise myself hopefully. It would be good to get a better understanding of the immune system
No worries, Rosie. I've taken many courses on coursera and other sites and, while I've finished a handful, there are many others I started but didn't finish. Even when I don't finish a course, I learn a lot! I am so grateful to have these opportunities!
