Thanks @OmarIthawi !

@OmarIthawi What does CAPA stand for? I understand they are problems/exercises. I web searched and see it referenced in some places in edX pages, but none I look at actually spells out the acronym

Great question @johnbaldwin! It makes a nice brotherhood name.

I don't know, so I had to look it up. It looks like it's a short for LON-CAPA, which is a short for: "Learning Online Network with Computer-Assisted Personalized Approach". A circa 2007 LMS.

In the Open edX context it means: "(multiple choice, drop down, etc)".

edx-platform/common/lib/xmodule/xmodule/capa_module.py

Lines 22 to 29 in facccb9

	class CapaModule(CapaMixin, XModule):
	"""
	An XModule implementing LonCapa format problems, implemented by way of
	capa.capa_problem.LoncapaProblem
	CapaModule.__init__ takes the same arguments as xmodule.x_module:XModule.__init__
	"""
	icon_class = 'problem'

So basically edX copied whatever there's in LON-CAPA in terms of both problem types and underlying format.
