Could the Voynich Manuscript be a private educational system?

I also wonder whether the author could have been someone highly intelligent but outside formal academic structures, possibly even a woman with limited access to official education in the 15th century. Such a person might have created a private symbolic system to organize botanical, medical and astrological knowledge gathered from fragments of learning available around them.

In general, I agree that the manuscript was created for educational purposes. But I don't think this is the personal notebook of a very smart person, and it's also obvious that the manuscript is not a visual manual.
Rather, some kind of conditional community of anatomists decided to write down their knowledge in encrypted form, so that they could later show it to other students and use it themselves. Or maybe other students were not included in this scheme, and the community just made the book for themselves.
