Let's start with the Guardians. Guardians work best when they have a specific place set aside for studying, generally with a desk, proper lighting, and a computer as needed. It is usually important for them to make sure everything is in its proper place. A piece of paper not neatly lined up can drive them to distraction. They like to get everything they need in one place, organize it, and then get to work. Guardians usually do best with an environment which is restful or business-like, but not too stimulating.

Inspectors (ISTJ) work best in a very quiet environment with no interruptions. Inspectors will generally start their studying and end their studying with a completely clean desk. William's study corner looks like a shrine. Everything is organized neatly in drawers while the surfaces are free of all dust and dirt. The best environment for Inspectors is a space that can be closed off, is removed from phones and people, and is orderly.

Supervisors (ESTJ) are usually a little more comfortable with mess than Inspectors. They also tolerate a lot more noise, but interruptions can easily derail them. Supervisors often do well with a study partner. Talking out loud can help them get a handle on the material they are learning. Taryn studies for history with Michael. They each develop questions based on the material. Then they test each other. Taryn's grades have gone up.

Providers (ESFJ) still like order, but they are the most tolerant of the Guardians of some mess. They often like to have a study group. Lauren is in a study group for economics with three other women. Over time, they have developed a breakdown of jobs so everything gets covered. They also spend part of each session in girl talk. Providers are the most likely of the Guardians to get off-topic when studying since they find the latest people happenings much more fascinating.

Protectors (ISFJ) are the most sensitive of the Guardians to the emotional atmosphere. They have difficulty studying when there is unresolved conflict. Garrett's roommates are having a fight and trying to make Garrett the middle man. He really doesn't want to get involved, but the only way he's found to get them off his back when he's home is to study. Then he's too busy to talk. His studying is less productive because of the conflict, but he's doing so much of it, he's actually learning more.
