Top 10 Majors Backed Up by AP Biology

The AP Biology exam primarily supports majors and fields related to biology and the life sciences. It is designed to assess a student’s understanding of fundamental concepts in biology and their ability to think critically and apply that knowledge.

Some of the majors and fields that the AP Biology exam can support include:

1. Biochemistry: Biochemistry majors study the chemical processes that occur within living organisms, and a strong foundation in biology is essential.

2. Neuroscience: While neuroscience is a specialized field, a solid understanding of the biological basis of the brain and nervous system can be advantageous, and AP Biology provides a good foundation for this.

3. Agricultural Sciences: Those interested in agriculture and crop sciences can benefit from a strong biological foundation, as it’s relevant to plant biology and agriculture.

4. Biomedical Sciences: Students pursuing careers in research or healthcare may find the foundational knowledge in biology from the AP exam helpful.

5. Environmental Studies: This interdisciplinary major combines aspects of biology, ecology, and sustainability, making AP Biology knowledge valuable.

6. Microbiology: Understanding the fundamentals of life sciences is crucial for microbiology, which deals with the study of microorganisms.

7. Ecology and Conservation Biology: AP Biology covers principles related to ecosystems, population dynamics, and conservation, which are vital in these majors.

8. Molecular Biology and Genetics: These majors focus on the molecular and genetic processes in living organisms, and a good grasp of biology is essential.

9. Environmental Science: Understanding ecological principles and ecosystems is crucial in this field, and AP Biology covers many relevant topics.

10. Zoology and Botany: These majors focus on the study of animals and plants, respectively, and AP Biology provides a foundational understanding of these organisms.
