One of the important aspects of the E2R System is to build one "Memory Scene" on another.
See how all of thes 4 Anatomy scenes interact and one scene helps you with another.
We have the same thing with history, zoololgy and other courses.
You are not learning 40+ presidents, or 26 phyla, or 4 enzymes.
You are learning one scene where all of the items relate to each other.
One item helps you remember all of the others.
Use the E2R scenes to help you get started and build your own inventory of scenes.
Plan to make this a permanant part of your memory. You should rmember facts from the 8 th grade when you ae 80 years old
