Introduction

The Biology E/M test assesses your understanding of general biology at the college preparatory level.

How to Choose Biology E or M

  • Take Biology E if you feel more comfortable answering questions pertaining to biological communities, populations, and energy flow.
  • Take Biology M if you feel more comfortable answering questions pertaining to biochemistry, cellular structure and processes, such as respiration and photosynthesis.
  • Indicate choice of Biology E or Biology M on your answer sheet on test day.

Topics on the Test

Material Skills (for both E and M)
E M      
≈15% ≈27% Cellular and Molecular Biology

Cell structure and organization, mitosis, photosynthesis, cellular respiration, enzymes, biosynthesis, biological chemistry

≈30% Knowledge of Fundamental Concepts

Remembering specific facts; demonstrating straightforward knowledge of information and familiarity with terminology

≈23% ≈13% Ecology

Energy flow, nutrient cycles, populations, communities, ecosystems, biomes, conservation biology, biodiversity, effects of human intervention

≈35% Application

Understanding concepts and reformulating information into other equivalent forms; applying knowledge to unfamiliar and/or practical situations; solving problems using mathematical relationships

≈15% ≈20% Genetics

Meiosis, Mendelian genetics, inheritance patterns, molecular genetics, population genetics

≈35% Interpretation

Inferring and deducing from qualitative and quantitative data and integrating information to form conclusions; recognizing unstated assumptions

≈25% ≈25% Organismal Biology

Structure, function, and development or organisms (with emphasis on plants and animals), animal behavior

   
≈22% ≈15% Evolution and Diversity

Origin of life, evidence of evolution, patterns of evolution, natural selection, speciation, classification and diversity of organisms

   

Choose Your Test

On test day you'll indicate if you're taking Biology-E or Biology-M by gridding the code for the chosen test on your answer sheet. Only questions pertaining to the test code that is gridded on the answer sheet will be scored. You may not take both Biology-E and Biology-M on the same test day.

Anticipated Skills

  • Ability to recall and understand the major concepts of biology and to apply the principles learned to solve specific problems in biology
  • Understanding of simple algebraic concepts, including ratios and direct and inverse proportions, and the ability to apply such concepts to solving word problems
  • Ability to organize and interpret results obtained by observation and experimentation and to draw conclusions or make inferences from experimental data, including data presented in graphic and/or tabular form
  • Familiarity with the metric system of units

Due to the differences in high school biology courses, you may find that some questions are on unfamiliar topics.

Recommended Prep

  • One-year college preparatory course in biology (either a general survey course, or one with emphasis in ecology or molecular biology)
  • One-year course in algebra (or one year of an integrated math sequence)
  • Experience in the laboratory

Remember, calculators are not allowed.
