Anyone use mind maps here?

I’ve always thought about the test as sections within each session. For instance, on level 2 it was “master pension accounting” and then “master financial asset account.” They never linked. Here I’m beginning to see overlap with, say, the BF theory and the TF ideas on MVF versus BPT. Has anyone utilized mind maps in their studying to help relate the sessions to one another, or would it be a waste of time versus just putting in the time to memorize/understand the lists given session by session?
