Grade 12 · Chemistry · Semester 1 · 2026–2027

The semester, mapped out like reaction pathways through chemical dynamics.

Every week your student advances through the fundamentals of physical and organic chemistry — starting with reaction rates and thermodynamics, balancing chemical and acid-base equilibria, and diving deep into organic carbonyls, carboxylic acids, and molecular chirality.
