For context: I'm studying nursing and I haven't fully fleshed out these documents because I started this method only fairly recently. Lots of memorization involved I my classes and I haven't retained last semester's information. And later classes build on top of each other heavily. Some of the classes I've taken are:

Pathophysiology Pharmacology Fundamentals & Health Assessment

Each of these classes/subjects have their own link to a document (except I actually find it easier to have Health Assessment and Fundamentals combined into one link/document).

Each link/document can have several sheets, which help me organize the material within these subjects by organ system. For example, for Pathophysiology I have it divided into the following sheets all in one link:

Cardiovascular System Respiratory System Integumentary System Nervous System Urinary System Digestive System etc

So now I can organize all my information from my classes in a way that's very easily accessible and easy to understand. The tables are organized, sorting everything by Disease Name, Definition/Pathophysiology, Causes/Risk Factors, Signs and Symptoms of the Disease (including the reason these manifestations occur), and potential complications that the disease may lead to down the road.

If this were Pharmacology, it would be separated by Drug name, Drug Class, Mechanism of Action, Side Effects, etc.

It's super nice to have everything all in one place, easy to find, easy to understand, easy to compare/contrast, and easy to edit. Plus, it's all saved online in the cloud (I used to do written notes with multiple notebooks I wouldn't even really go back to). I highly recommend this method of studying for subjects that are memorization-heavy.
