A clear TEAS study guide for future nursing and healthcare students. Learn what to study, how to practice, what mistakes to avoid, and how to build confidence before test day.
Use this page as your TEAS hub. Start with strategy, then move into the practice tools that match the sections you need most.
Understand the four sections, timing pressure, and the type of thinking each section rewards.
Use anatomy, body systems, medical terminology, and lab-style practice to make science questions feel less random.
Do not just count your score. Track why you missed each question: content gap, rushing, wording, calculation, or confusion.
Use timed sets during the final stretch so pacing does not surprise you on test day.
Most students do not struggle because they lack all knowledge. They struggle because they study too broadly, hesitate under pressure, misread questions, or fail to recognize what the question is actually asking.
The TEAS rewards organized preparation. You need to know the content, but you also need to practice reading questions carefully, eliminating wrong answers, and moving through timed sets without panic.
The TEAS is not just about memorizing facts. It is about recognizing patterns quickly under pressure.
If terminology slows you down in science questions, review: Medical Terminology Guide or Top 100 Medical Terms.
The TEAS exam tests your ability to apply knowledge across four major areas:
Identifying main ideas, supporting details, conclusions, author purpose, and evidence from passages.
Solving calculations, percentages, ratios, proportions, measurements, and word problems.
Understanding anatomy, physiology, biology, chemistry basics, scientific reasoning, and body systems.
Reviewing grammar, punctuation, sentence structure, word meaning, spelling, and language use.
You do not need perfection in one section. You need consistency across all sections and a plan for your weakest areas.
The Test of Essential Academic Skills (TEAS) is a nursing school entrance exam used by many nursing and allied health programs. The exam helps schools evaluate a student's readiness for healthcare education by testing reading, mathematics, science, and English language skills.
The TEAS is commonly required for:
The TEAS does not test advanced nursing knowledge. It evaluates the academic foundation needed to succeed in nursing school.
The ATI TEAS exam contains 170 total questions, including scored questions and unscored pretest questions used for future exam development.
| Section | Approximate Questions | What the Section Measures |
|---|---|---|
| Reading | 45 | Main idea, supporting details, inference, author's purpose, and passage evidence. |
| Mathematics | 38 | Numbers, algebra, measurement, data, ratios, percentages, and conversions. |
| Science | 50 | Anatomy, physiology, life science, chemistry basics, and scientific reasoning. |
| English and Language Usage | 37 | Grammar, punctuation, sentence structure, vocabulary, and standard English usage. |
Because exam formats can change, always verify current details through ATI Testing and your nursing program.
The TEAS test covers four academic areas that support success in nursing school: reading, mathematics, science, and English language usage. The goal is not to test advanced nursing knowledge. The goal is to measure whether you have the foundation needed for early healthcare coursework.
Practice main idea, details, inference, evidence, author's purpose, and passage organization.
Practice fractions, decimals, percentages, ratios, proportions, equations, measurements, and conversions.
Practice anatomy and physiology, biology basics, chemistry basics, body systems, and scientific reasoning.
Practice grammar, punctuation, sentence structure, word meaning, spelling, and language usage.
If you are unsure where to start, take a mixed set of TEAS practice questions first. Your missed questions will show which section needs the most attention.
A strong TEAS plan does not treat every section the same. Each section requires a different study method.
| TEAS Section | What to Focus On | Best Practice Method | Common Mistake |
|---|---|---|---|
| Reading | Main idea, details, inference, evidence, author purpose, passage structure | Short timed passages with answer review | Answering from memory instead of checking the passage |
| Math | Fractions, decimals, ratios, percentages, equations, measurements, conversions | Show every setup step before solving | Rushing the setup and choosing the wrong operation |
| Science | Anatomy, physiology, biology basics, chemistry basics, scientific reasoning | Body system review plus practice questions | Memorizing isolated facts without connecting function |
| English | Grammar, punctuation, sentence structure, word meaning, spelling, prefixes and suffixes | Rule review followed by sentence correction practice | Going by what “sounds right” instead of applying rules |
If you only have limited study time, prioritize your weakest section first, then rotate through mixed practice so you do not lose strength in other areas.
Stop studying like this:
Start studying like this:
Improvement comes from fixing mistakes, not just doing more questions.
A structured study plan helps prevent random studying. Use this as a simple starting point and adjust based on your school deadline and baseline score.
Take practice questions, identify weak sections, and review the types of questions you miss most often.
Focus heavily on anatomy, physiology, math setup, reading strategy, and English rules.
Mix all sections together so you get used to switching between question types.
Use timed sets, review mistakes, and build confidence with pacing before exam day.
The TEAS is much easier to prepare for when you improve small weaknesses every day instead of trying to memorize everything at once.
For many future nursing students, science is the section that feels the most intimidating. The key is to study systems and relationships instead of memorizing random facts.
Know major organs, body systems, basic functions, and how systems work together. Use visual labeling practice to build recognition.
Review cell structures, DNA basics, tissues, homeostasis, and how living systems maintain balance.
Understand pH, acids and bases, bonding basics, molecules, and why chemistry matters in body systems.
Practice reading charts, identifying variables, interpreting results, and understanding simple experiments.
If you struggle with anatomy, start with Anatomy Labeling Practice. If medical words slow you down, use How to Study Medical Terminology.
Focus on identifying the main idea, supporting evidence, and what the question is really asking. Do not rely only on memory of the passage. Go back to the text when needed.
Set up the problem first, then solve. Many math errors happen because the student understood the concept but set up the equation incorrectly.
Focus on body systems and relationships. Anatomy is easier when you understand what each structure does and how it connects to the rest of the body.
Start here: Anatomy Labeling Practice
Focus on grammar rules, punctuation, sentence clarity, prefixes, suffixes, and word meaning. If word parts slow you down, use: Medical Prefix and Suffix Practice.
Many students jump randomly between subjects and lose momentum. A better strategy is to build recognition first, then use mixed practice.
Start anatomy review here: Anatomy Labeling Practice.

Many wrong answers come from misreading the question, not from having no knowledge.
You are getting ready when:
Readiness is not about feeling perfect. It is about seeing consistent improvement and knowing how to handle missed questions.
Use these examples to see how TEAS questions often test recognition, not just memorization.
Question: Which body system is primarily responsible for gas exchange?
Question: A student correctly answers 36 out of 45 questions. What percent is correct?
Question: If a paragraph explains several reasons sleep affects memory, what is most likely the main idea?
Question: Which sentence is written correctly?
Good preparation is not only about what you know. It is also about how you manage the exam.
The goal is not to feel like every question is easy. The goal is to stay calm, use strategy, and make the best choice available.
The TEAS exam becomes much easier when you stop studying randomly. The goal is not to read every topic once. The goal is to identify your weak areas, practice the exact skills being tested, and review mistakes until the same pattern no longer causes missed questions.
Many students find science hardest because it combines anatomy, physiology, biology, chemistry, and scientific reasoning. The fastest way to improve is to study body systems as relationships, not isolated facts.
Focus on the major body systems, organs, functions, and how systems work together to maintain homeostasis.
Review cells, organelles, DNA, tissues, inheritance basics, and the organization of living systems.
Review atoms, molecules, bonds, pH, acids, bases, solutions, and chemical reactions in the body.
Practice variables, hypotheses, experiments, graphs, data tables, conclusions, and evidence-based reasoning.
| Body System | What to Know | Common TEAS Clue |
|---|---|---|
| Cardiovascular | Heart chambers, blood flow, arteries, veins, capillaries, blood pressure | Left ventricle pumps oxygenated blood to the body. |
| Respiratory | Air pathway, lungs, alveoli, diaphragm, oxygen and carbon dioxide exchange | Alveoli are the main gas exchange site. |
| Nervous | Brain, spinal cord, nerves, sensory input, movement, coordination | Cerebellum helps with balance and coordination. |
| Digestive | Mouth, stomach, small intestine, large intestine, liver, pancreas, gallbladder | Small intestine absorbs most nutrients. |
| Urinary | Kidneys, ureters, bladder, urethra, filtration, fluid balance | Kidneys filter blood and make urine. |
| Endocrine | Hormones, glands, insulin, glucagon, thyroid, adrenal glands | Insulin lowers blood glucose. |

TEAS math is not just about calculation. Most mistakes happen during setup. Before solving, decide what the question is asking and what operation is needed.
| Skill | What to Practice | Common Mistake |
|---|---|---|
| Fractions | Add, subtract, multiply, divide, simplify, compare | Using the wrong denominator or skipping simplification |
| Decimals | Place value, rounding, converting between decimals and fractions | Moving the decimal the wrong direction |
| Percentages | Percent of a number, percent increase/decrease, test scores | Forgetting that percent means out of 100 |
| Ratios and proportions | Set up equal ratios and solve for missing values | Setting up the proportion backwards |
| Measurement | Units, conversions, metric prefixes, word problems | Not checking whether the final unit matches the question |
Percent = part ÷ whole × 100
Average = total ÷ number of values
Proportion = one ratio set equal to another ratio
Area of rectangle = length × width
Volume of rectangular prism = length × width × height
Question: A student answers 42 out of 50 questions correctly. What percent did the student get correct?
Question: If 3 notebooks cost $12, how much do 5 notebooks cost at the same rate?
Reading questions often test whether you can find evidence, identify the main idea, and avoid choosing an answer that sounds true but is not supported by the passage.
| Question Type | What It Asks | Best Strategy |
|---|---|---|
| Main idea | What is the passage mostly about? | Look for the broad point that includes the details. |
| Supporting detail | Which detail is stated or supported? | Return to the passage and verify the exact evidence. |
| Inference | What can reasonably be concluded? | Choose what follows from the text, not outside knowledge. |
| Author purpose | Why did the author write this? | Decide whether the author informs, persuades, explains, or entertains. |
| Vocabulary in context | What does a word mean in this sentence? | Use the surrounding sentence, not just the dictionary meaning. |
Mini passage: Sleep helps the brain process information learned during the day. Students who sleep enough often perform better on memory-based tasks than students who stay up all night studying.
Question: What is the main idea?
For English and Language Usage, do not rely only on what sounds right. Learn the rules that appear repeatedly.
Singular subjects need singular verbs. Plural subjects need plural verbs.
A complete sentence needs a subject and a verb and must express a complete thought.
Two complete sentences cannot be joined with only a comma.
Commas often separate introductory phrases, items in a list, and independent clauses joined by conjunctions.
A pronoun should clearly refer to one noun.
Use prefixes, suffixes, roots, and sentence context to understand unfamiliar words.
Question: Which sentence is correct?
| Days | Focus | Goal |
|---|---|---|
| Days 1–3 | Baseline practice and missed-question tracking | Find your weakest section. |
| Days 4–10 | Science and anatomy review | Build body system recognition. |
| Days 11–15 | Math setup and calculation practice | Reduce careless setup errors. |
| Days 16–20 | Reading and English practice | Improve comprehension and grammar rules. |
| Days 21–25 | Mixed practice sets | Practice switching between sections. |
| Days 26–30 | Timed review and weak area repair | Build test-day pacing and confidence. |
Which structure is the primary site of gas exchange?
Which organ filters blood and produces urine?
What is 25% of 80?
If a passage lists several benefits of exercise, what is most likely the main idea?
