Why do you need to do this? As a Ni, this should come easy to you. You need to trust your intuition and allow the knowledge you pick up on coalesce in the background on it's own; this is what Ni-types are good at. Ni take things in and it knows. Ni-types don't need to try and turn this into a conscious process. It's already in their heads. They make the connections unconsciously and then look for application with their Fe and Ti.
What you're doing here, breaking things down and hoarding more and more knowledge, and the way you described it as a forest, it actually kinda sounds rather Fi-Ne-ish to me...
This would be the ideal, but the problem I've found with certain subjects is that they don't necessarily make sense to my intuition. . . so I end up going through some crazy bullshit mental process that doesn't suit me to try to memorize stuff.
Personally I have a terrible time memorizing names of anything. It's why I always hated history classes, and was drawn into science. There are definitely famous people in science, but the learning and testing is rarely about naming them, but on the system that was built by them . . . history classes are ONLY about naming them, even though it's the impact on history which should be the main point. I can easily remember anyone's actions, or impact on a given topic. . . . those silly words that people use to identify a person never seem to stick. Worst grade I ever got was when I took a greek mythology class . . . I could have summarized any story we read and discussed it's meaning and importance, but the test was multiple choice:
Who was the first robber Theseus met?
a) Pheotheces
b) Periphetes
c) Phycrotes
I had no clue . . . if only I could have written in "the guy with the club"
I've heard that some people think in words, and that they need a word to describe something in order to have a place in their memory for it. I think in pictures for the most part, and the only reason I associate words with those things I'm thinking of are when I have to describe it to someone else. It is incredibly common for me to go about describing something as, "you know those things on doors that people have to turn to get it to open" . . . though less efficient, that explanation seems fully sufficient in describing the object I'm imagining. Names just seem like a trivial formality.
The problem with that, is that I don't do well with words as a source of information. Words can start to build the picture in my mind. . . but it doesn't necessarily build the right picture for what the professor wants. Think to something like physics and acceleration due to gravity. You can describe it with equations:
X = Gt^2 + Vit + Xi
V = Gt + Vi
A = G
The descriptions of all those only make sense to me because I can visualize the plots of what they mean, and their impact on reality . . . only then can I start assigning meaning to those equations and build them into my understanding of the topic. It seems most other people can take those equations at face value and manipulate them from there, but they don't have a good grasp on how that translates into the reality of the physical world.
In coming to understand what a professor expects, I've found that old exams are awesome. It seems they often make them available these days because it's more fair than random people passing them around, and others being left out. These give real examples of what they're actually grading, the style of the questions, and hints at what they believe are the most important points.
