MogyBear,
Astrowill answered your question about themes, so you have some assurance on that point.
You then asked If you use it for textbooks (like a biology textbook), can you learn all of the info thoroughly?
If it takes you 2 hours to learn a chapter in biology, using the PhRing Whole Mind System, you will lessen your study time by a third in the beginning. But, it's a SYSTEM which means steps as opposed to step.
If you practice the full system and get it down, then you'll see the time factor for studying going down. For students, it sure helps to also have memorization techniques in your school career toolbox. Peg systems, links, associations, acronymns, creative sentences, Memory Optimizer, Buzan books in your personal toolbox.
So what i'm getting at is that you are not going to learn the PhRing technique and skip studying; rather you'll lessen the amount of time you need to gather your facts.
Then, using MindMapping and memory techniques, you'll get the material down.
