Biology study guide
Biology · Work through your exam, one topic at a time.
The Biology exam is a general, multiple-choice assessment of foundational biological knowledge, organized into five weighted domains: molecular and cellular biology (25%), genetics and evolution (20%), organismal structure and function (20%), ecology and environmental biology (15%), and scientific inquiry, data analysis, and laboratory skills (20%). It is designed for candidates who need to demonstrate broad biological literacy - students preparing for further science coursework, candidates entering health or life-science training programs, and educators or technicians who want an independent check of their knowledge. The Biology study guide has 5 sections and about 2,013 words.
01Molecular and Cellular Biology
The Molecular and Cellular Biology domain tests how cells are built, how they move molecules and energy, and how they regulate reactions, signaling, and division. Expect items that connect structure to function: membrane composition to transport, organelle anatomy to metabolism, and protein shape to catalysis.
439 words, about 2 min02Genetics and Evolution
Genetics and Evolution tests inheritance patterns, how allele frequencies change, and how populations diverge. Questions often require probability calculations, interpretation of pedigrees or crosses, and distinguishing evolutionary mechanisms from outcomes.
380 words, about 2 min03Organismal Biology: Structure and Function
Organismal Biology: Structure and Function examines how animals and plants maintain internal stability, exchange gases and materials, transport substances, and coordinate responses. Items typically ask you to predict a physiological consequence from anatomy or from a feedback loop.
421 words, about 2 min04Ecology and Environmental Biology
Ecology and Environmental Biology tests population dynamics, species interactions, community structure, energy and nutrient flow, and conservation. Expect graph interpretation and questions that ask you to separate short-term change from long-term equilibrium.
383 words, about 2 min05Scientific Inquiry, Data Analysis, and Laboratory Skills
Scientific Inquiry, Data Analysis, and Laboratory Skills tests experimental design, measurement quality, graphing, basic statistics, and common bench techniques. Questions often present a scenario and ask what conclusion is supported, what control is missing, or how to calculate a concentration or colony count.
