...what are you waiting for?
Mastering Real Estate Investment: Examples, Metrics and Case Studies not only takes you through the key calculations that every real estate investor needs to understand, but also through four sample investment scenarios that are very much "real world:" a single-family home as a rental, a re-hab project, an apartment building, and a small shopping center.
This is some of the same material I teach in my grad-school classes. Skip the dorm life and dining hall food, and go directly to a fuller understanding of how investment real estate really works.
