SAT2科目中SAT2生物是很多同学愿意选择的科目，SAT2生物考点一直备受同学们的关注。

　　The Biology E/M test contains 60 general biology questions followed by 20 questions in each of the special sections: Biology E or Biology M. You can select the area in which you feel most confident, and, after completing the 60 core questions, you can then take either the Ecological or Molecular sections. That selection can be made when you take the test by filling in the appropriate code for the section you wish to take. You cannot take both sections on the same test date.

　　The test covers the following areas.

　　Cellular and Molecular Biology — 12%

　　Ecology — 12%

　　Classical Genetics — 10%

　　Organismal Biology — 30%

　　Evolution and Diversity — 11%

　　Ecology/Evolution (Biology E Test) — 25%

　　Molecular/Evolution (Biology M Test) — 25%

　　In order to take this test and do well, you should have completed at least a one-year course in biology. In addition, it would be helpful to have also taken algebra, in order for you to understand basic algebraic concepts. Since you will not be allowed to use a calculator while taking this test, it is also important to have basic mathematical skills, although the calculations you will encounter will be fairly simple. In addition, you will encounter some questions utilizing the metric system, so you should brush up on this topic.
