Concise Summary of AP Biology Course and Exam Description

  • AP Biology Overview

    • College-level course for high school students.
    • Covers evolution, cellular processes, genetics, and ecology.

  • AP Course Structure

    • 8 Units:
    1. Chemistry of Life
    2. Cell Structure and Function
    3. Cellular Energetics
    4. Cell Communication and Cell Cycle
    5. Heredity
    6. Gene Expression and Regulation
    7. Natural Selection
    8. Ecology
    • Each unit has specific learning objectives and exam weightings.

  • Science Practices

    • 6 practices students must develop:
    1. Explain biological concepts
    2. Visual representations
    3. Questions and methods
    4. Represent and describe data
    5. Statistical tests and analysis
    6. Argumentation

  • Exam Format

    • 3 hours total:
    1. Multiple-Choice: 60 questions (50% of score)
    2. Free Response: 6 questions (50% of score)
    • Assessment of students' understanding across units and science practices.

  • Key Exam Topics:

    • Evolution principles, genetic variation, processes of life (metabolism, cellular processes), and ecological interactions.
    • Focus on analysis, interpretation of data, and experimental design throughout the course.

  • Laboratory Component

    • 25% of instructional time must be spent in labs.
    • Integrates inquiry-based investigations to apply concepts.
    • Lab work enhances understanding of scientific principles and practices.

  • Important Equations:

    • Hardy-Weinberg Principle: p^2 + 2pq + q^2 = 1 , with p+q=1
    • Surface area-to-volume ratios for cells to maximize diffusion efficiency.
