The Course

This course is offered to highly motivated students who wish to pursue their interests in the life sciences. The College Board recommends a successful completion of high school biology and high school chemistry, before commencing AP Biology, although the actual prerequisites vary from school to school and from state to state. Many schools, for example, require no background in biology to take the course. There are critics of the AP program that believe that the high school science curriculum does not adequately prepare students with a background college-level scientific studies and that students who have studied AP Biology do not perform as well in college science classes as might be expected of someone who successfully completed an AP course in the subject matter.

Topics covered

Topics covered by this course include:
  • Anatomy
    Anatomy
    Anatomy is a branch of biology and medicine that is the consideration of the structure of living things. It is a general term that includes human anatomy, animal anatomy , and plant anatomy...

     & Physiology
    Physiology
    Physiology is the science of the function of living systems. This includes how organisms, organ systems, organs, cells, and bio-molecules carry out the chemical or physical functions that exist in a living system. The highest honor awarded in physiology is the Nobel Prize in Physiology or...

  • Biochemistry
    Biochemistry
    Biochemistry, sometimes called biological chemistry, is the study of chemical processes in living organisms, including, but not limited to, living matter. Biochemistry governs all living organisms and living processes...

  • Biodiversity
    Biodiversity
    Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire planet. Biodiversity is a measure of the health of ecosystems. Biodiversity is in part a function of climate. In terrestrial habitats, tropical regions are typically rich whereas polar regions...

  • Botany
    Botany
    Botany, plant science, or plant biology is a branch of biology that involves the scientific study of plant life. Traditionally, botany also included the study of fungi, algae and viruses...

  • The Cell
    Cell (biology)
    The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life. The Alberts text discusses how the "cellular building blocks" move to shape developing embryos....

  • Developmental biology
    Developmental biology
    Developmental biology is the study of the process by which organisms grow and develop. Modern developmental biology studies the genetic control of cell growth, differentiation and "morphogenesis", which is the process that gives rise to tissues, organs and anatomy.- Related fields of study...

  • Ecology
    Ecology
    Ecology is the scientific study of the relations that living organisms have with respect to each other and their natural environment. Variables of interest to ecologists include the composition, distribution, amount , number, and changing states of organisms within and among ecosystems...

  • Evolution
    Evolution
    Evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organisation, including species, individual organisms and molecules such as DNA and proteins.Life on Earth...

These topics that are covered may change due to a new course curriculum that will take place in 2013. The new course description is now on College Board. It will include less of the topics information to be known about some of the topics above and will focus on more important topics and lab procedures.

The exam

The AP test
Advanced Placement Exams
Advanced Placement examinations are taken each May by students at participating American, Canadian, and international educational institutions. The tests are the culmination of year-long Advanced Placement courses. All but one of the AP exams combine multiple-choice questions with a...

 for this course consists of two sections. Section I, administered over a period of 1 hour 20 minutes (80 minutes), consists of 100 multiple-choice questions. Section II, which lasts 1 hour and 30 minutes, consists of 4 essay prompts to be answered comprehensively by the student. A mandated 10 minute reading period is held prior to beginning to write the four essays. The 10 minutes provided for the reading period are NOT included in the total 1 hour and 30 minutes allowed for writing the essays; during this time, a student may record notes in the exam booklet containing the essay prompt, though the booklet used to record official essay responses must remain sealed until the reading period is completed. Overall, the exam thus lasts 180 minutes, or three hours.

The exam grade is weighted unevenly between Section I and Section II, with 60% of the score dependent on success in Section I and the remaining 40% determined by results from Section II.

Most colleges award credit in an introductory biology course for a score of 3 or higher. Higher tier schools generally only accept a score of 4 or 5.

Grade distribution

In the 2007 administration, 144,796 students took the exam from 8,486 schools. In the 2008 administration, the exam grades were recalibrated, resulting in a substantial decrease in the top scores and increase in the bottom scores. In the 2009 and 2010 administrations, 159,580 and 172,512 students took the test, respectively.

The grade distributions for 2007, 2008, 2009, and 2010 were:
Score 2007 2008 2009 2010
5 18.2% 18.6% 19.5% 18.7%
4 20.3% 15.6% 15.5% 15.1%
3 21.2% 16.1% 15.8% 15.4%
2 23.2% 15.2% 15.1% 14.1%
1 15.9% 34.6% 34.0% 36.6%
Mean 3.04 2.68 2.71 2.65
