Understand the TEAS Science Section

If you always feel overwhelmed with the TEAS test science section, worry no more; this part will answer most of your questions. This science section tests students in different areas, including biology, chemistry, scientific reasoning, physiology, and human anatomy. Some subtopics you could encounter include human biological systems, scientific research methods, cell biology, chemical reactions, and genetics.

1. Questions Format and Breakdown

The TEAS test science section covers a total of 50 questions. There are 44 scored questions and 6 unscored questions. Below is the breakdown of the questions:

  • Biology scored questions – 9
  • Anatomy and physiology scored questions – 18
  • Scientific method scored questions – 9
  • Chemistry scored questions – 8

The 6 unscored multiple-choice questions will not count in the final result nor be identified by test-takers. Remember, the paper version will give you a question stem and four answer options. Other question types are available in the online edition, such as drag-and-drop, typing your response, and clicking on the proper image.

Your objective will be to select the best answer based on your knowledge and understanding of the subject. You can use the proctor’s simple calculator or a drop-down calculator that will display on the screen. Scientific calculators with specific functions are not permitted, but scratch paper can be used to take notes. Manage your time effectively during the test to attempt all questions in the allocated time.

2. Length of the TEAS Test

Like the other test sections, the TEAS science section is timed. It should take 60 minutes. However, the science section accounts for only a portion of the total test period. The time limit for completing all four sections is 209 minutes.
Consequently, you should plan your time strategically to ensure that you cover all of the questions. Understanding the question types and becoming accustomed to the topics presented will allow you to establish effective strategies for approaching the TEAS test science section. This will allow you to organize your time better, focus on the most relevant key areas, and increase your chances of success.

Effective Study Strategies for Success

Preparing for the TEAS test science section necessitates a deliberate approach to developing knowledge and skills in various scientific concepts. Here are some useful recommendations to help you study and prepare:

1. Understand the Topics

Familiarize yourself with the topics covered in the TEAS science section. This encompasses life sciences, physics, and scientific reasoning. Review the ATI topic outline to ensure you understand the major ideas in each section.

2. Take TEAS Science Practice Tests

Taking TEAS science practice tests can help you examine your knowledge and become familiar with the format and style of questions in the TEAS science section. These assessments can reveal significant information about your skills and limitations, allowing you to focus your study efforts.

Review your answers after taking the practice tests and ensure you understand the explanations provided. Identify any points where you struggled or made mistakes. This will allow you to identify your deficiencies and prioritize those areas. Concentrate on improving your comprehension of concepts you find difficult to grasp.

3. Use Science Study Materials

In addition to practice tests, employ TEAS study resources to solidify your knowledge. Look into alternative resources like credible science textbooks, educational websites, and instructional YouTube videos.

This broad approach can help you gain fresh perspectives and improve your comprehension. Ensure you only use materials from reliable sources, such as the online platform. These well-structured materials touch on all examinable aspects of the test. Take as many practice tests as possible. These will help you familiarize yourself with the test format and timing. You will also pinpoint your weak areas and address them appropriately.

4. Emphasize Key Scientific Concepts

Science is a broad subject and requires some level of commitment to grasp all concepts. To ace your TEAS test science section, consider looking at some of these key scientific concepts in science. By understanding these topics, you are one step ahead as far as passing the test is concerned:

  • Genetics
  • Cell Biology
  • Human biological systems
  • Kinetic and potential energy
  • Human anatomy and physiology

Test-taking Tips and Strategies for the TEAS Science Section

1. Manage Your Time

Time management is crucial when handling any TEAS test, especially the science section. Here are some tips to help you manage time effectively during the exam:

  • Plan time accordingly – allocate different time limits for every section in the science test. For example, you can look at the total number of questions to handle and the time allocated and then divide to get the time required to answer each question.
  • Prioritize questions – avoid spending too much time on one question. If you encounter a challenging question, put a mark on it and handle the easier ones first. That way, you will answer more than wasting time on a single question. If time allows, you can return to the challenging questions after tackling the simple ones.
  • Avoid overthinking. You can always trust your instinct and write the first response that comes to mind. Do not overthink a question, as this will only waste time that could be used to tackle other questions.

2. Think Critically

Critical thinking is an important skill in handling science questions for the TEAS test. It will enable you to analyze, evaluate, and make decisions based on the evidence provided. Critical thinking will help you comprehend complex concepts by breaking them into manageable parts. Critical thinking also helps in problem-solving, allowing you to devise strategic ways to tackle challenging questions. It also helps to avoid misinterpretation and, hence, more accurate answers.

Application of Critical Thinking in Answering TEAS Test Science Section

  • Read carefully – pay close attention when reading and identify key variables and terms and how they relate.
  • Evaluate options – critically analyze every answer and eliminate any obvious incorrect answers.
  • Use prior knowledge – using your knowledge of scientific principles, assess the validity of every answer, and choose one that aligns with what you know.
  • Predict outcomes—before picking an answer, you could predict the outcome and eliminate answers that lead to improbable conclusions based on your knowledge.

Honing your critical and reasoning thinking will make your work easier when sitting for the TEAS test. Apply these TEAS science tips to pass the exam.


The TEAS test science section is not complicated in the exam. All you have to do is prepare adequately, and you will pass. Ensure you use reputable online resources such as tutorials and TEAS prep courses. Some students even prefer to look for a personal tutor to help them understand the concepts better, which is also a great option.
