ATI TEAS Science can jump from body systems to chemistry, biology, experiments, and data in the same practice session. NursingMocks keeps the work focused on Science so you can answer questions, review what you missed, and see whether the issue is content knowledge, prompt wording, or evidence.
Start Practice by Set
Choose a Science set to start a new test, continue an unfinished one, or review a completed set. After the set, use the missed-answer pattern to decide whether to spend more time on Human Anatomy and Physiology, Biology, Chemistry, Scientific Reasoning, prompt wording, or evidence-based questions.
Use the guide navigation to move through the full saved content without scrolling through one long article.
The official ATI TEAS Science section gives you 60 minutes for 50 questions. Of those, 44 are scored and 6 are unscored pretest questions.
Science section detail | Value |
Total questions | 50 |
Scored questions | 44 |
Unscored pretest questions | 6 |
Time limit | 60 minutes |
Human Anatomy and Physiology | 18 scored questions |
Biology | 9 scored questions |
Chemistry | 8 scored questions |
Scientific Reasoning | 9 scored questions |
Human Anatomy and Physiology has the largest scored share, so it should not be treated lightly. Still, Science is not only A&P. Biology, Chemistry, and Scientific Reasoning each test a different kind of thinking.
Answers to common questions about using NursingMocks for ATI TEAS Science practice.
Choose a Science set, answer the questions, and review your results after the set. The page is built for Science-only practice, so you can focus on Human Anatomy and Physiology, Biology, Chemistry, and Scientific Reasoning without moving through the other TEAS subjects.
NursingMocks Science practice is organized around the ATI TEAS Science areas: Human Anatomy and Physiology, Biology, Chemistry, and Scientific Reasoning. Use the sets to see which area is causing the most missed questions.
No. NursingMocks is an independent practice resource. It does not provide official ATI questions and does not claim affiliation, authorization, or endorsement from ATI.
Yes. After completing a set, use your missed answers to find the pattern behind the score. The issue may be a knowledge gap, a relationship error, a prompt interpretation error, or an evidence error.
Start with a full Science set if you are not sure where the weakness is. If your results show repeated misses in body systems, then move more attention to Human Anatomy and Physiology.
Choose the next set based on what your last review showed. If you missed chart or experiment questions, practise more Scientific Reasoning. If you missed body-system questions, spend more time with Human Anatomy and Physiology.
