Watching the Ferguson video reminded me of the 4-color briefing methods.

Generally, the color coded journaling methods are color coding very surface things or applicable things, not conclusions and main points.
By the end of my paralegal studies, I was using a 4-color pen, a pencil, and a yellow highlighter very systematically. I have found myself marking up my current handwritten notes and coursebook with pencil, yellow highlight, and red pen, without any real plan, yet.
I am on lesson 6 of the WVBS Genesis course, and there is a video on doctrine that appears to be preparation for the term paper, and a bunch of videos on Noah's ark. There is so much distraction from the excellent outlines of the Bible text that are the core of the coursebook, and remind me of my law studies.
I really appreciate the link to that video, Mikey: it was timely.
