CLEP Natural Sciences cheat sheet

A condensed reference for the formulas, graph-reading rules, and must-know facts most worth reviewing before exam day.

Biology essentials

  • Cell theory; DNA → RNA → protein; mitosis vs meiosis.
  • Genetics: dominant/recessive, Punnett squares.
  • Evolution by natural selection; ecology (food chains, cycles).

Physical science + method

  • Energy is conserved; kinetic vs potential; basic forces and motion.
  • Matter: atoms, elements, states, simple reactions.
  • Scientific method: hypothesis, independent/dependent variables, control group, valid conclusions.

Practice this first: Biological science — Cells, genetics, evolution, and ecology are roughly half the exam.

Reviewing the sheet is step one. Passers are usually hitting about 70-80% on realistic practice before test day (CLEP costs about $93, with a 3-month retake lockout on a miss), so the fastest way to know you are ready is to start answering real questions.
