Is there a proper way to take a case?

Ok. As a practitioner, you have read the Organon, or… you have attended lessons where the Organon was read to you and the teacher explained what was required.

Now, given the variety of practices that are used under the banner of Homoeopathy, It seems that depending upon your teachers bent, you may or may not have been taught Hahnemannian case taking. So.. I ask again, is there a proper way to take a case, and if so, what is it.?

Your comments please.
