SAT Biology Subject Test: Your Questions Answered

While SAT and ACT tests are a standard part of applying to colleges, many students also find themselves confronted with the SAT Subject Tests. In short, these 20 separate tests cover specific topics such as math and biology.

The SAT Biology Subject Test, also known as Biology SAT II, is one of the more popular in this group of extra SAT tests because most high schoolers take Biology classes in high school and find the subject less intimidating than physics or chemistry.

Taking the SAT Biology Subject Test is not only a great way to stand out from other applicants, but it can also fill some requirements of selective schools. It’s especially a good idea for students that plan to study biology at university.

If you’re planning on taking the exam, but aren’t sure where to begin, the experts at AdmissionSight are here to clear the air. We’ve put together a helpful guide to answer all of your questions surrounding the SAT Biology Subject Test.

What is the SAT Biology Subject Test?

The SAT Biology Subject Test is actually composed of two separate parts. Students can opt to take the Biology Molecular (Biology M) or Biology Ecological (Biology E) tests. While there are definitely some overlaps, the former tends to focus more on cellular processes, cellular structure, and biochemistry.

The latter, on the other hand, leans towards energy flow, populations, and biological communities. Both versions of the SAT Biology Subject Test have to be taken in one-hour and feature 80 multiple-choice questions. The score you receive will range anywhere between 200 to 800. Unlike some other SAT Subject Tests, no calculators are allowed to be used during the exam.

Many students are surprised to realize that 60 of the questions between the two tests are completely identical. It’s only the final 20 that are specialized for either Biology E or M. Both exams are offered on SAT Subject Test dates December, November, October, August, June, and May.

When should I think about taking the SAT Biology Subject Test?

Before we can dive into the differences between the Biology E and M tests, it’s pertinent to look at the reasons a student might consider taking the SAT Biology Subject Test over the 19 other potential options. Here are some specific cases when AdmissionSight would recommend a student to go this route:

1. You recently took a biology course.

Ideally, you could take the SAT Biology Subject Test immediately following a biology course in high school. This not only drastically cuts down on studying time you have to dedicate to the test, but it also ensures that all of the concepts you learned in class are still fresh in your mind.  Having laboratory experience, a year-long course in algebra and a biology course focused on college preparation are additional benefits that would make it a great idea to take the Biology Subject Test. If you’re in AP Biology and have already prepped for an AP test, you can rest assured that the Subject Tests aren’t as difficult as their AP counterparts. If you find yourself in this position, you’re more than prepared.

2. You have yet to take a science-related Subject Test

Many colleges require, or at the minimum recommended, applicants, to take one SAT Subject Test in the sciences and one in the humanities. Of course, there are some outlying schools that want more specific tests due to their specialties. Students who find themselves required to complete this qualification but remain wary about taking a science-related Subject Test might want to consider opting for the biology exam. Typically, students find it much easier to handle than the Chemistry or Physics Subject Tests. This can be boiled down to the fact that the Biology test includes fewer difficult calculations and advanced concepts. Relying on basic logic and memorization is usually enough to get you by. This way, you’ll be fulfilling college requirements without sacrificing a good score.

3. You’re interested in pursuing biology in the future.

These subject tests are a great way to illustrate to colleges your specific interest in a given field and your dedication to pursuing it as a future career. If you envision yourself being a biologist or holding a position within the field after college, it’s clear that you should take the SAT Biology Subject Test. Even if you only plan on pursuing this field academically and not professionally, it’s still a good option. You’ll be able to demonstrate your ability to handle the concepts and your willingness to put forth the effort needed to succeed. If you already have established a trend of academic interest for biology in your application, this Subject Test will only work to tie it together more completely and impressively – something that can always help you stand out more to admission officers.

 What does the SAT Biology Subject Test Contain?

Assuming some or all of the factors listed above apply to you, and you’ve decided to take the test, there’s still one more decision to make: Biology E or Biology M?

On the exams

Topics

Percentage of Each Subject Test

EM
Molecular and cellular biology

Subtopics: biological chemistry, biosynthesis, enzymes, cellular respiration, photosynthesis, mitosis, cell organization, and cell structure

15%27%
Ecology

Subtopics: human intervention, biodiversity, conservation, biomes, ecosystems, communities, populations, nutrient cycles, energy flow

23%13%
Genetics

Subtopics: population genetics, molecular genetics, inheritance patterns, Mendelian genetics, meiosis

15%20%

Subtopics: animal behavior, development of organisms (especially with regard to animals and plants), function, structure

25%25%
Diversity and evolution

Subtopics: diversity and classification of organisms, speciation, natural selection, patterns of evolution, evidence of evolutions, the origin of life

22%15%

As these charts illustrate, there are more questions about Molecular and Cellular Biology on the SAT Biology M Subject Test. Alternatively, more questions about Ecology are found on the Biology E Subject Test. Clearly, their names offer a good indication of what can be found on each exam. You might notice that there’s a slightly greater number of Genetics questions on Biology M while Biology E seems to have slightly more on Diversity and Evolution.

Both exams feature the same amount of questions regarding Organismal Biology. If you’ve recently taken a biology course or have any experience in the field for that matter, these topics should be fairly familiar to you. Keep in mind though that a good majority of the topics and even the questions are identical between these tests.

What kind of skills are tested on the SAT Biology Subject Test?

Knowing what subjects are covered on the Subject Tests is only one half of the battle. The other half is learning what kind of skills will be tested. As you become more familiar with collegiate-level testing, you’ll notice that there is a stark difference between being familiar with a subject and being able to display certain skills with that knowledge. Keeping that in mind, here are the different skills tested on both the Biology E and M Subject Tests:

  • Recall certain facts and fundamental concepts. This takes up roughly 30% of each test.
  • Apply your knowledge of biology to practical examples offered on the exam and solve problems by applying some math as well. This constitutes around 35% of each exam.
  • Make inferences and form deductions based on both quantitative and qualitative data. This accounts for about 35% of each test.

When broken down like this, you can see that nearly 70% of questions on the overall SAT Biology Subject Test will offer you a certain scenario and require you to make calculations and assumptions about it. The remaining 30% is easily distilled to basic biological facts. They’re straightforward, easy to remember and don’t take up much time during the exam. Therefore, it’s equally important to know the general concepts of biology, such as the basic steps of an experiment, as well as some more specific facts. You’ll need to synthesize these skills on the exam.

How can you decide between the E and M SAT Biology Subject Tests?

Now that you have a better idea of the similarities and differences between Biology E and M, it’s time to decide which is better for you. The experts at  AdmissionSight recommend you take Biology E if you’re more confident in your ability to answer questions regarding energy flow, populations, and biological communities.

On the other hand, we’d recommend opting for Biology M if you’re more comfortable in your ability to handle questions regarding biochemistry, cellular processes, and cellular structures. If these answers seem pretty straightforward, it’s because the differences between the tests are clear, making it easier to decide between the two. If you really want to take both exams, you can, but not on the same day. To properly indicate which test you want to take, circle the associated circle on the answer sheet you’re given on test day.
