Track your progress before test day
50% of your score on the AP biology exam is based on the multiple-choice question. By practicing and tracking your progress, you can go into test day with confidence on the MCQ question and ready to apply your knowledge on the Free Response Questions (FRQ).
All about AP Biology
Aligned with the rigorous course content defined by the College Board, this examination delves into the fundamental principles that govern life. From the intricate mechanisms of cell communication to the marvels of gene expression, students explore the big ideas shaping the field of biology. Through a blend of multiple-choice questions, students demonstrate their comprehension of structure and function at various biological levels. They unravel the mysteries of natural selection and its impact on the diversity of life forms.
Master multiple-choice questions for every AP Bio unit
AP Biology History has eight units, covering the chemistry of life to ecology. Our platform offers specific practice questions for each unit to build confidence for test day.
Unit 1: Chemistry of Life
Master the properties of macromolecules like nucleic acids, proteins, and lipids that form the foundation of biological systems.
Unit 2: Cells
Explore cell structure, including plasma membranes, cell size constraints, and the importance of compartmentalization in cellular efficiency.
Unit 3: Cellular Energetics
Study cellular energy flow, focusing on enzyme catalysis, cellular respiration, and the production of ATP.
Unit 4: Cell Communication and Cell Cycle
Understand signal transduction pathways, tonicity, and the complex regulation of cell cycle checkpoints.
Unit 5: Heredity
Tackle meiosis, Mendelian genetics, and the complexities of non-mendelian genetics and chromosomal inheritance.
Unit 6: Gene Expression and Regulation
Practice questions on DNA replication, transcription, translation, and the regulation of gene expression.
Unit 7: Natural Selection
