You actually learn by doing. You could master each and every one of these skills with Basic Open Water Certification and experience, the best teacher.
To be clear, you can also die this way too. I agree that fish ID, etc dont make better divers, and only meaty courses should be allowed for MSD. However, some classes are great for a safer entry into territories that aren't familiar to a diver. Even the military doesn't say "here is the water, here is your air, go get some experience." Please dont misunderstand, I hold military divers in the highest regard. Nevertheless, experience alone is a ****ty teacher that will kill you without hesitation. Now guided experience is a different story.
