The point of reviewing the introductory and aid material is to help focus my attention on those other areas of knowledge that are most useful for the development of science. I intend to widen my coverage of physics and chemistry, begin another review of astronomy, and widen my coverage of biology; I've just finished a review of cell biology and will be looking at organisms.
In the area of personal studies, I've finished a review of the human body in time to start over with all major sections.
I've also started looking at human geography. In areas of culture, I've finished a look at graphics and am going on to mathematics, finished a review of performing arts and moved on to events, and finished a review of transportation technology and am going to communications technology.
My studies of the institutions of society has been too slow lately, so I've started a double track and am looking at both economics and government.
In history, I've started at the beginning with prehistory; currently taking a look at the 4th-8th millennia BC, and I'm also looking at the early classical period, with the 5th century BC, which includes the classical Greeks and the decline of the Persian Empire.
