On the day of the test, you will decide to take the Biology E (Ecology) test or the Biology M (Molecular Biology) test. You may not take both tests on the same test day. Here’s how you should decide which test to take:
Biology Ecological (Biology-E)：Leans more toward biological communities, populations and energy flow
Biology Molecular (Biology-M)：Geared toward biochemistry, cellular structure and processes, such as respiration and photosynthesis

Take the Biology E test if you are more comfortable with questions about energy flow, biological interactions, and populations and communities. This section of the biology test is focused on ecology.
Take the Biology M test if you are more comfortable with topics such as biochemistry, cellular biology, and processes such as photosynthesis and respiration. This section of the test concentrates on molecular biology.
选择考生物科目的同学只需要选择其一就好，Biology-E和Biology-M都是80到题，前面60个题是完全一样的，后面20个有所不同。Biology-E偏重于生态方向，Biology-M偏重于分子方向。
选择E，意味着生态之类的题目多一些，做E部分的20个题目，就是60-80;
选择M，意味着分子，遗传等之类的题目多一些，做M部分的20个题目，就是80-100。
其实虽然分出E和M，但是天道小编提醒考生，不会说我选择M的部分，生态就不考，只是说会比例小一点，而分子部分比例大一点，反之亦然。
有人说选E和M的方法很简单，你物理好就选E，化学好就选M。当然个人觉得这种观点是偏颇的。
所以说，选E和M还是要看个人兴趣所在。 |
