Not too easy. Not too difficult.
Dr. Coursen is an excellent resource for anything to do with physiology and health care. You may not realize this as he is very humble, but he was previously a fairly high ranking person in the Samaritan Health Care (now Banner Health / Honor Health). He definitely knows his stuff!
Dr. Coursen would often go on tangents related to the material offered. If you pay attention they will definitely help you remember the material, and they're pretty interesting. This course taught me a great deal about physiology, but the histology was definitely my favorite.

Advice for students:
Dr. Coursen recommends you buy a CD with some physiology learning software. Get it. It is pretty awesome for learning the material. He also tests material directly covered by it.
