The Science section of the TEAS tests your foundational knowledge of chemistry, human anatomy, physiology, and general biology. To help you prepare for this section of the TEAS, this page contains everything you need to know, including what topics are covered, how many questions there are, and how you can study effectively.

If you are wanting to be fully prepared, Mometrix offers an online TEAS prep course. The course is designed to provide you with any and every resource you might want while studying. The TEAS course includes:

Hi! My name is Megan DuMond, and I recently took the DAT on MAY 2 and received my unofficial scores of a 23AA, 22TS, and 23PAT. I am a full-time student and military member at the United States Air Force Academy. While studying for my test I was concurrently taking 15.25 credit hours and performing my military duties. I studied from the beginning of January (Jan 6) to the day of my test (May 2). My recorded hours of studying came to about 240 hours.

I was hoping for a slightly higher score in this section, as I was averaging around a 23 on my practice tests. My method of choice was to read every question in a section, then start reading through the passage and highlighting as I went, returning to answer the questions I saw in the passage. On my real DAT, the transition between questions lagged quite a bit, up to like 5ish seconds, so if you choose this method I would say plan for a little less time. Overall, find a method that works for you, and perfect it.

I was really proud of this section. I struggled on the ACT and SAT in math, so I knew I would have to put a little extra work into this section. Doing practice problems, and learning how to do problems with the shortcuts that Bootcamp teaches is crucial to finishing this section on time. I would highly recommend doing the practice question banks on problems that you struggle with.

My scores on this section would bounce back-in-forth from a 19-20 to a 24 in this section. Same as RC, find a rhythm that works for you, and stick with it. I personally jumped to Angle Ranking, Hole punching, Cube counting, and pattern folding, and then jumped back to TFE, and then Keyholes. Do practice problems, and then actively see if you just guessed, or actually got your reasoning right by checking the explanation that Bootcamp gives you. It is a very useful tool.

When a few founding organisms make it to an isolated area, niche differentiation can lead many new species to evolve in a process called adaptive radiation. Darwin came up with his theory of evolution by natural selection based on the species he found on the Galapagos Islands, where adaptive radiation had occurred. The history of evolutionary theory, the mechanisms of natural selection and evolution, and the different types of evidence we have for evolution are all fair game, as is the evolutionary history of humans and other species.

Humans are real game-changers in the process of evolution. Social biology includes a look at how human populations grow and how we are affecting other organisms and our environment (pollution, genetic engineering, habitat destruction, etc.) and ourselves (modern medicine).

Science is a process, and you will be expected to understand something about how to design experiments, collect data, and interpret experimental evidence. This will be incorporated into the topics of the exam already described.

You may be given some experimental evidence to interpret or be asked about how information is collected or hypotheses are made, or even about the social consequences of scientific endeavors. So be sure you understand something about the scientific method and experimental design, as well as human impacts on the biosphere.

Explanation: The highest enzyme activity is seen around this temperature. It's likely that the enzyme operates at around this temperature in whatever organism it was extracted from. At 100 C, the enzyme doesn't seem to be working at all. Probably it was denatured and inactivated by the heat.

Explanation: Eutrophication can happen naturally but is often accelerated and more severe due to human activities. Eutrophic lakes can sometimes disappear entirely, becoming filled in by the sediments from dead organisms and bacteria.

Explanation: Homologous structures are thought to be evidence of evolution because the same basic body plan appears to have been adapted over time to perform different functions. Vestigial structures are homologous structures that have lost their use, such as the tiny vestigial tailbone in humans. Analogous structures perform the same functions, but aren't actually related. The wing of a butterfly and the wing of the bird are examples of analogous structures.

I. Both uracil and thymine nucleotides will pair with adenosine

II. The genetic code is redundant

III. Single nucleotide substitutions rarely have much effect

IV. The substitution is likely to be detected and repaired because DNA does not ordinarily contain uracil.

I. Pyruvate is converted to Acetyl Coenzyme A

II. In the mitochondrion, electron carriers donate electrons to the electron transport chain to produce a proton gradient.

III. A molecule enters the citric acid cycle, or Krebs cycle, leading to the production of 3 NADH, 1 FADH2, and 1 ATP

IV. During glycolysis, a molecule is cleaved into two parts, producing 2 NADH and 2 ATP molecules

V. ATP synthase admits protons into the interior matrix of the mitochondrion, producing up to 34 ATP.

Explanation: Stabilizing selection favors intermediate traits and tends to cause traits to cluster more tightly around an optimum value. Directional selection causes traits to become more extreme in a favored direction. For example, if the fastest cheetah gets more prey and so is more likely to survive, then there is selective pressure for cheetahs to get faster and faster. Disruptive, or diversifying, selection favors a lot of variation. The human immune system is under disruptive selection, because the more variation we have in our receptors to recognize invading pathogens, the better.

Two sperm travel down the pollen tube to the embryo sa One fertilizes the egg, and the other fertilizes a polar nucleus to produce diploid endosperm. Two sperm travel down the pollen tube to the embryo sa One fertilizes the egg, and the other fertilizes the two polar nuclei to produce triploid endosperm. The zygote splits in two. One of these cells produces the embryo, and the other makes the endosperm. The endosperm is produced entirely by the maternal cells, without the need for fertilization.

While quite short on the study side of things, the official CLEP book is the go-to final practice test. Since this is the only official practice test available, I normally use it as my final spot check before taking the test.

REA offers a great combination of study guide and practice questions. This book functions well as the central pillar of a strong CLEP prep strategy, with resources like the Official CLEP Study Guide (above) providing a great final practice test at the end.

All U.S. and Canadian dental schools require their applicants to take the DAT as part of the admission process. Each school uses its own criteria to determine how to weigh DAT results as part of admission decisions.

Prospective dental students should take the DAT during the second semester of their junior undergraduate year, or during the summer between junior and senior years. Make sure you have taken the subjects covered by the test, especially organic chemistry.

The DAT is offered year-round at Prometric Test Centers throughout the U.S. and Canada (except the providence of Quebec). Once you have received your eligibility letter confirming that your test application has been accepted, you must contact Prometric to secure an appointment. We recommend doing this at least 60 to 90 days before your desired test date, since schedules fill up. Visit the Prometric website to find a testing center near you, see current COVID-19 procedures, and schedule your test.

All fee waivers that were available have been granted. Additional fee waivers will be available starting July 1. On that date you will be able to follow the instructions below to submit a fee waiver request. The following information is for informational purposes only.

In documented cases of severe financial hardship, a limited number of partial fee waivers are available to DAT examinees each calendar year (January - December). The partial fee waiver covers 50% of the DAT fee. The partial fee waiver does not apply to any charges associated with rescheduling/canceling a test date or score reporting after the time of initial application. Partial fee waivers are granted on a first-come, first-served basis to eligible examinees who have submitted the required documents.
