In the first major category, focus 25% on cells, 25% on DNA, and 50% on organization and interaction. Cells should cover theory, history, types, structure, and integration with DNA. DNA should cover structure, inheritance, and the genome. Organization and interaction should cover biological tiers, reductionism, structure-function, ecosystems, energy conversion, and regulatory mechanisms.
In the second major category, focus half on diversity and unity and half on evolution. Diversity and unity should cover species, domains, and kingdoms. Evolution should cover history, diversity, natural selection, and descent with modification.
In the third major category, focus 75% on the scientific method and 25% on science and technology. The scientific method should cover inductive reasoning, the steps of the method, control and experiment groups, and theories. Science and technology should cover conceptual aspects.
