Chem / Phys

Chemical and Physical Foundations of Biological Systems

Tests general and organic chemistry, physics, and biochemistry — all applied to biological systems. Quantitative reasoning heavy.

Expect dimensional analysis, equation manipulation, and applying physics/chemistry to physiology. Memorizing formulas isn't enough — you need to apply them.
