Students often underestimate Chemistry of Life because it appears early in the syllabus, but AP questions here test application, not memorized definitions alone.
Biochemical foundations: water properties, macromolecules, and chemical reactions vital to living systems. Expect questions involving Properties of water, pH, buffers; Structure and function of macromolecules: carbohydrates, lipids, proteins, nucleic acids; Basic energetics of biochemical reactions.
Mix MCQ practice with sketching diagrams or timelines from memory. AP Biology rewards recall under time pressure, not just recognition.
