Total of 80 questions answered by each student:

• 60 multiple-choice questions that are common to both Biology-E and Biology-M

• 20 specialized multiple-choice questions for either Biology-E or Biology-M

Questions cover topics emphasized in most high school courses. Because of course differences, most students will find that there are some questions on topics with which they are not familiar. You may not be able to complete all the questions in the time given, but it’s not necessary to get every question correct to get a high score or even the highest score on the test.

The first 60 of the 80 questions are common to both Biology-E and Biology-M, followed by 20 specialized questions for each section.
How to Choose Between Biology-E and Biology-M

Take Biology-E if you feel more comfortable answering questions pertaining to ecology, evolution, and diversity. Take Biology-M if you feel more comfortable answering questions pertaining to biochemistry, cellular structure, and processes, such as respiration and photosynthesis. Once you decide which emphasis to take, you need to fill in the appropriate circle for the test you have chosen on your answer sheet. Important: If you change your mind, you must change the bubble on the answer sheet to match your test; otherwise, your answers to the 20 specialized questions will not be scored correctly.

You are not allowed to take both Biology-E and Biology-M on the same test date. You can take them on two different test dates.

Skills Covered in Both Biology-E and Biology-M

Knowing fundamental concepts; remembering specific facts; demonstrating straightforward knowledge of information and familiarity with terminology (about 30% of test)
Understanding concepts and reformulating information into other equivalent forms; applying knowledge to unfamiliar and/or practical situations; solving problems using mathematical relationships (about 35% of test)
Interpreting, inferring, and deducing from qualitative and quantitative data and integrating information to form conclusions; recognizing unstated assumptions (about 35% of test)

Important Things to Note on This Subject Test

Calculator use is not permitted.
Problem solving requires simple numerical calculations.
The metric system of units is used.

Cellular and molecular biology:Cell structure and organization, mitosis, photosynthesis, cellularrespiration, enzymes, biosynthesis, biological chemistry

（E：15%， M：27%）
Ecology: Energy flow, nutrient cycles, populations, communities, ecosystems,biomes, conservation biology, biodiversity, effects of human intervention
（E：23%， M：13%）
Genetics:Meiosis, Mendelian genetics, inheritance patterns, molecular genetics,population genetics
（E：15%， M：20%）
Organismal biology:Structure, function, and development of organisms (with emphasis onplants and animals), animal behavior
（E：25%， M：25%）
Evolution and diversity:Origin of life, evidence of evolution, patterns of evolution, naturalselection, speciation, classifi cation and diversity of organisms
（E：22%， M：15%）

以上数据内容可以帮助决定是考Biology E 还是 Biology M，同时可以估计一下多少内容还没学，已拟定学习复习计划。
