AP Biology Course Overview and Exam Preparation Notes

About AP Biology

  • Course Framework and Resources: Provides a detailed description and a roadmap for students and teachers to follow throughout the course.

  • AP Program Overview: Founded in 1900, the College Board promotes educational excellence and equity. It offers programs and services in college readiness, including AP courses.

  • Equity and Access Policy: College Board encourages equitable access to AP courses for all academically prepared students and aims to eliminate barriers for underrepresented groups.

Course Overview

  • AP Biology Course: Equivalent to a two-semester introductory college course. Success in this course prepares students for the AP Biology Exam and potential college credit.

  • Laboratory Requirement: 25% of the instructional time is devoted to hands-on lab work emphasizing inquiry-based investigations.

Course Framework Components

  1. Science Practices: Focus on skills like explanation, analysis, and argumentation to engage in science.
  2. Course Content: Organized into units representing key concepts in biology, aligned with college coursework.
  3. Big Ideas: Central concepts include evolution (EVO), energetics (ENE), information storage and transmission (IST), and systems interactions (SYI).

  • Key Concepts: Interactions between species, responses to environmental changes, and conservation.

Instructional Approaches

  • Lab Focus: Engage students in inquiry-based labs where they learn through experimentation and data collection, reinforcing scientific practices.
  • Strands of Inquiry: Incorporate multiple strategies from rich resources, including primary scientific literature, to deepen content understanding and facilitate critical thinking.

Exam Overview

  • Structure: The AP Biology exam consists of 60 multiple-choice items (50%) and 6 free-response items (50%). Skill assessments include explanation, visual representation analysis, questions and methods, data representation, and argumentation.
  • Competencies Assessed: All student learning objectives are measured to evaluate understanding of biological concepts and their applications in real-world scenarios.
