Here is a shortlist (for a detailed discussion see: Advantages of incremental learning).
In short, with incremental learning you learn fast, you acquire massive loads of knowledge, retain memories for life, remember almost all that you have learned, understand things better, develop harmoniously in all directions, enhance your creativity, and all that while having incredible fun!
That knowledge is relatively stable and lasts in student's memory as long as the process continues, and well beyond.
The cost of high knowledge retention is very small when compared with various traditional learning methods.
Incremental learning is the fastest and the most comprehensive way of learning available to students at the moment of writing (2013).
Incremental learning is a consolidation of computer-based techniques that accelerate and optimize the process of learning from all conceivable material available in electronic form, and not only.
In incremental learning, we often quickly move from one subject to another.
Such interruptions may occur many times during a single learning day. It is true that incremental learning may lead to "learning impatience" and "craving interruption", however, these have never been proven detrimental beyond showing that once you employ incremental learning, you may never want to go back to traditional "book at a time" learning.
Narrow horizons and narrow perspectives only make it harder to further rationalize the selection of the learning material.
Incremental learning is the opposite of the irrational school system learning in which a heavy focus is put on just a few areas of knowledge in a semester (at the cost of other, equally important, areas of learning).
If that sounds too good to be true, please read more below or just give it a solid try.
