Additional Things to Know
How to Choose between Biology-E (Ecological) and Biology-M (Molecular)
- Take Biology E if you feel more comfortable answering questions about biological communities, populations and energy flow.
- Take Biology M if you feel more comfortable answering questions about biochemistry, cellular structure and processes, such as respiration and photosynthesis.
- Indicate choice of Biology E or Biology M by filling in the appropriate circle on your answer sheet for the test you have chosen to take on test day. You must indicate Biology E or Biology M on your answer sheet on test day for the test to be scored correctly
- You cannot take both tests on the same test date, but you can take them on two different test dates.
Please note that this test reflects what is commonly taught in high school. Due to differences in high school classes, it’s likely that most students will find questions on topics they’re not familiar with. This is nothing to worry about. You do not have to get every question correct to receive the highest score (800) for the test. Many students do well despite not having studied every topic covered.
