I've been taking Master's courses from them since the summer of 06, and will be 50% complete in AUG 07.

Most of the instructors are superb, they are also very flexible in assignments as required.

Most of the courses I've taken are paper-writing based, although all of them also have had a discussion board that you need to use for grades - it surrounds the topics that you are reading about. I have not taken a single test yet.

Can't recommend them highly enough - where else can one study Unconventional Warfare?
