AP Biology Examination 2025: A Complete Overview

The AP Biology examination, a rigorous evaluation of scholars’ information and understanding of organic ideas, will bear important modifications in 2025. These modifications intention to align the examination extra carefully with present scientific practices and research-based pedagogy. This text supplies an in-depth overview of the AP Biology examination 2025, highlighting key modifications and offering steering for college kids and educators making ready for the examination.

The revised AP Biology examination will encompass two major parts: a multiple-choice part and a free-response part. The multiple-choice part will embody 80 questions, growing from 60 within the present format. These questions will cowl a broad vary of subjects from molecular biology to ecology and evolution. The free-response part will stay largely unchanged, consisting of six open-ended questions requiring college students to show their analytical and problem-solving abilities.

One of the important modifications to the AP Biology examination 2025 is the incorporation of a “Science Practices” part inside the multiple-choice element. This part will comprise roughly 10 questions and assess college students’ capability to interact in scientific inquiry, analyze knowledge, talk scientific arguments, and relate science to societal points. The inclusion of this part aligns with the growing emphasis on scientific literacy in increased training and workforce readiness.

Moreover, the 2025 AP Biology examination can be extra student-centered, with an emphasis on formative evaluation and suggestions. The School Board will present lecturers with a spread of sources, together with apply supplies, evaluation instruments, {and professional} growth alternatives, to help college students of their studying journey.
