Review Every TEAS Science topic On The Test
The science section of the ATI TEAS is arguably the most difficult section. There’s probably not a person out there who has taken the TEAS that will tell you that science wasn’t the hardest most in-depth area.
For this reason we’re going to do a deep dive into all the topics you might see on the test. We’ll go over all the topics but also some of the more anecdotal things like tips, strategies and the types of questions that you might see.
The science section of the TEAS is going to have 50 questions in 60 minutes.
The test does have unscored questions, for this section 44 questions are scored and 6 questions are unscored, but you won’t know which ones.
A&P is by far the area you need to know the most about, and roughly 18 of the 50 questions will be on A&P.
So this is your high value topic that you should be spending the most time studying.
The Smart Edition Academy online course covers every topic covered on this page in a very detailed way so that you can really learn and understand each topic, and you have the option to learn it with lesson modules, video lessons, test banks, flashcards, and practice tests.

Cardiovascular System
You will see lots of questions on the cardiovascular system on the TEAS.
You need to know the flow of the heart like the back of your hand. You will likely have 3-4 questions on the cardiovascular system.
One great tip that can help you is to draw or label diagrams of the heart with your book or online course closed, if you can do this then that’s how you know that you’re really starting to understand how these systems work.
In the Smart Edition Academy online course, we have a lot of diagrams and illustrations that go into detail on this topic with interactive questions.
An example would be where you have to drag and drop the labeling of the heart or an EKG chart which really helps you to know this system by working with interactive questions and activities like this. Practice more questions like this in our Free TEAS science practice test.
@smart_edition_academy Hey prenursing students! It’s Nurse Melissa with a helpful mnemonic for remembering blood flow through the heart. 🫀🩸 it’s “TP MA” or Toilet Paper My A—!

A&P Support and Movement: TEAS Science Practice Test
Skeletal System
The lesson from the Smart Edition Academy TEAS online course introduces the anatomy and functions of the skeletal system.
This lesson also explores how bone forms, remodels, and constantly changes as a person grows.
When a human is born there are 270 bones in the body and as you grow bones fuse together. By the time you are an adult you have 206 bones.
The skeletal system consists of bones, cartilage and ligaments, you should know what they are, what they do and how they work.
There are two main parts to the skeletal system:
- axial skeleton
- appendicular skeleton
It’s likely you’ll see questions on bone shape and structure so you should know the types of bones:
- long bones
- flat bones
- irregular bones
- sesamoids
- short bones
@smart_edition_academy Can you answer this TEAS 7 practice question? The overall structure of bone consists of an outer shell called compact bone. It closes another type of bone tissue that is loosely organized called spongy bone. Compact bone is made up of units called osteons. These structures look like cylinders they contain a mineral, matrix and living bone cells. The tibia is a long bone and it is designed to provide strength and flexibility, and it has spongy bone on the inside. This spongy bone is important because it is lightweight, it absorbs shock, it has red bone marrow, and it helps provide support flexibility. ##prenursingmajor##prenursingstudent##prenursingschool##futurenurse##atiteas7##teas7 ♬ original sound - SE Nursing
An example of what you are not going to see on the test is “What is a flat bone?”
That’s too easy. That’s not what the TEAS is about. The TEAS test is going to give you something more like:
“Which of these bones is a flat bone”? And then you’ll have a list of bones to choose from, so not only do you need to know what a flat bone is, you’ll need to go a step further and know, of the bones in the answer choices, which ones are flat bones.
That’s kind of the level of detail that you can expect, now that you know that, do your studying accordingly.
Make sure you are getting into those details and know that you can’t stop on that really topical level of just knowing the definition of a short bone.
Ossification and bone remodeling is also going to be a part of the skeletal system to know.
Check out this replay of one of our group tutoring sessions reviewing the Smart Edition TEAS online course skeletal system lesson module with Nurse Melissa.
