TEAS Science practice tests are a great way to study for one of the hardest exam sections. You might feel overwhelmed because you’ll be tested on chemistry, biology, anatomy and physiology, and the scientific method. Improving your TEAS test science score requires studying several tricky subjects.
Number of TEAS Science scored questions on the TEAS 7:
- 18 Anatomy and Physiology
- 9 Biology
- 8 Chemistry
- 9 Scientific Method
- 6 Unscored Questions (you won’t know which these are)

How to Use Your TEAS Science Practice Questions
You’ll have a little over a minute per question during the TEAS Science section. One of the best ways to prepare is to master and memorize specific topics. I call these High-Value Concepts. These are the concepts that are most likely to appear on every version of the test.
For example, some High Value Concepts for the TEAS Science section include:
- How the respiratory and cardiovascular systems work together
- How the endocrine and nervous systems communicate
- Bonding across the periodic table
- Monomers for biological macromolecules
- Differences between axial and appendicular skeletal bones
- Cellular organelles for energy production, protein synthesis, and replication
- Sites of carbohydrate, lipid, and protein digestion
When you are confident in these core concepts, you can buy yourself time for the harder, more complicated questions. Focusing on these kinds of questions can help you prepare to take the TEAS science test more easily too!
What kind of TEAS Science Questions will you see?
Every TEAS test will have the same number of scored questions across a standardized content map. When you prepare with TEAS science practice questions, make sure you cover each of the topics listed below.

TEAS Test Science FAQ
A “good” TEAS score is usually above 70%. Once students score in the 80s on the science section, they are usually in the 90+ percentile nationwide.
This is an important distinction! The percentile is like the curve of the TEAS test. Usually, if you are a pre-nursing student, you are used to getting As on your exams. But on the TEAS, getting a B (getting around 80 percent of the questions right) actually puts you in the top of the class across the country.
Read more about how to pass the TEAS.
You have 60 minutes to answer 50 questions on the TEAS 7, which means you have a little over one minute per TEAS science question.
Yes. These are confirmed scored questions on the ATI TEAS 7 in 2026. You will need to know the steps of mitosis and meiosis, and you’ll need to be able to compare and contrast them. For example, it’s good to know at which stage cells are haploid or diploid during meiosis.You will also need to be able to read a Punnett square and apply Mendel’s laws.
No, not in the science section. You’ll only get a calculator during the math section.
No. You will need to be familiar with trends, however. For example, you need to memorize that all elements in column one are alkali metals, transition metals have d orbitals, etc.
You don’t need to memorize positions of all the elements and their number of protons, etc. If a question requires information from the periodic table to answer, the TEAS will provide relevant information.
No. This might appear as an unscored question, but earth science is not a standardized section of the TEAS in 2026. This includes TEAS test science questions on plate tectonics and the earth’s atmosphere.
Probably not! These might appear as questions that are likely not scored.
Generally speaking, at least one month just dedicated to science. Since anatomy and physiology is such a large part of the TEAS, you’ll want to make sure you have time to commit lots of facts to memory.

Here’s what Prenursing Smarter student Alex said about my TEAS Science practice lessons: “I haven’t taken Anatomy or Physio yet, and Math/Bio/Chem haven’t been used in like 10 years. But I just got home from my first test attempt and managed an 82.3%. I’ll be submitting my application to a Nursing program this fall 🙂 The structure and information provided in your course was honestly so helpful.”
