About the Course
Students who plan to major in a science at the undergraduate level, or who are hoping to enter a pre-medical, pre-pharmacy or pre-veterinary program, can take an SAT Biology subject test to try to stand out from other college applicants. Both tests - the Biology Ecological (Biology-E) and Biology Molecular (Biology-M) - cover five content areas: cellular and molecular biology, ecology, genetics, organismal biology, and evolution and diversity. However, the percentage of questions focusing on each of these areas differs by test. For example, the Biology-E is highly focused on ecology and evolution and diversity, while the Biology-M is more concerned with cellular and molecular biology and genetics.
Our online biology course can help you prepare for both SAT Biology subject tests. The course opens with a chapter on science basics, before offering a review of inorganic chemistry and introducing organic chemistry. You'll also explore metabolic biochemistry, physiology and human genetics, as well as ecology and social biology. Other chapters in this course cover the following topics:
- Nucleic acids: DNA and RNA
- Cell biology
- Genetic mutations
- Cell division
- Plant reproduction and growth
- Animal reproduction and development
- Human impact on the environment
- The origin and history of life on Earth
- Phylogeny and the classification of organisms
- Analyzing scientific data
The Biology-E and Biology-M both feature 80 multiple-choice questions, which you'll have an hour to complete. These tests are offered just six times a year, with test dates in January, May, June, October, November and December.
SAT Biology Preparation & Registration
Our team of experienced, professional educators crafted the videos in this course to be brief and easy to follow yet comprehensive. Each lesson also includes a written transcript and a short, multiple-choice quiz, which allows you to test your mastery of the material.
Registration for the Biology-E and Biology-M tests can be completed by mail or through the College Board website. You must register at least a month before your preferred test date. When registering, you'll be prompted to choose up to four colleges or universities that you'd like to receive your test scores.
SAT Biology Scoring
Your score from the SAT Biology-E or Biology-M will be available online around three weeks after you take the test. Your report will indicate your total score, presented on a scale of 200-800, as well as your percentile rate, which compares your score to that of other test-takers. It also will give you your subscore in each of the following content areas:
Cellular and Molecular Biology
Questions on cell structure and organization, enzymes and biological chemistry are included in this section of the test. You also might be asked about the processes of mitosis, photosynthesis, biosynthesis and cellular respiration. Approximately 15% of the questions on the Biology-E focus on cellular and molecular biology, compared to 27% of the Biology-M.
This content area covers populations, communities, ecosystems and biomes. Questions also might focus on energy flow and nutrient cycles, in addition to conservation biology and effects of human intervention on the environment. The Biology-E features approximately 23% questions on ecology, while the Biology-M includes around 13%.
In this section of the test, you're likely to find questions on Mendelian, molecular and population genetics, as well as meiosis and inheritance patterns. Approximately 15% of questions on the Biology-E and 20% of questions on the Biology-M center on genetics.
Approximately one-quarter of the questions on both SAT Biology subject tests focus on organismal biology. You might be asked about the structure, function and development of plants, animals and other organisms, as well as animal behavior.
Evolution and Diversity
Around 22% of questions on the Biology-E and 15% of questions on the Biology-M revolve around evolution and diversity. This could include questions about speciation, as well as classification and diversity of organisms. This section also covers evidence and patterns of evolution, natural selection and origins of life.
