Section-Specific Strategy

Chem/Phys

Estimate before calculating: round constants ($g \approx 10$, $\ln 2 \approx 0.7$) and eliminate answers by magnitude and units. Unit analysis alone answers a surprising number of questions.

CARS

Never skim-and-hunt; read for the author's argument once, then answer from your map. The right answer is the most defensible modest claim — extreme wording ("always," "proves") usually marks a trap.

Bio/Biochem

Pathways and figures dominate. When a passage describes a mutant or inhibitor, trace one arrow at a time: what accumulates upstream, what disappears downstream.
