EDIT/FOLLOW-UP (my edit right just disappeared a minute ago):

Here is a link to example patient cases, which may help to see what kind of knowledge is useful. I was not trying to say it is all useless, when I had to solve sample cases e.g. in Medical Neuroscience (Coursera, huge course, great teacher) it sure helps to know the major pathways, and it would take too much time to have to look them up when the patient is in front of you.
