Also, while we're at it, ditch most of chemistry, beyond the basics (Conservation of mass, atoms and molecules, formulas for basic chemical reactions, combustion, acids and bases, temperature, pressure, and ideal gases, the common forms of matter are all good, and can be covered in three months, tops. You didn’t cut anything. You just described everything that is in a basic sophomore chemistry class and it does take a whole year. In regards to smaller class sizes, everyone wants that but no one wants to pay for it. Communities and politicians have bitter fights over 0.2% changes in education budgets when meaningfully changing class sizes would require increases of at least 50%. Source: I teach HS chemistry.
