The TEAS Science section tests your knowledge of human anatomy, physiology, biology, chemistry, and scientific reasoning.
This section plays a crucial role in nursing program admissions across the country. Strong performance here can make the difference between acceptance and rejection.
TEAS science questions cover complex topics that require thorough understanding and practice.
TEAS practice test sessions help you master these challenging concepts before exam day.
This guide provides comprehensive practice materials and proven strategies. You’ll uncover effective study methods and gain confidence for test success.
Understanding the TEAS Science Section Structure
The TEAS Science section follows a specific format designed to assess your readiness for healthcare education programs.
Understanding this structure helps you allocate study time effectively and approach each topic with confidence.
Section Format and Timing Requirements
The Science section contains 53 questions that must be completed within 63 minutes, allowing approximately 70 seconds per question. This timing requires efficient reading skills and quick decision-making under pressure.
The section includes both traditional multiple-choice questions and interactive formats like drag-and-drop exercises.
Alternative question types test the practical application of scientific knowledge rather than simple memorization, making thorough content understanding essential for success.
Subject Area Distribution and Topics
The TEAS Science section prioritizes healthcare-related content while maintaining a comprehensive approach to scientific knowledge.
Each subject area requires different preparation strategies based on question weight and complexity.
| SUBJECT AREA | QUESTION COUNT | PERCENTAGE | KEY TOPICS |
|---|---|---|---|
| Human Anatomy & Physiology | 32 questions | 60% | Body systems, organ functions, and physiological processes |
| Biology | 9 questions | 17% | Cell structure, genetics, evolution, ecology |
| Chemistry | 8 questions | 15% | Atomic structure, chemical bonds, reactions, and solutions |
| Scientific Reasoning | 4 questions | 8% | Scientific method, data analysis, experimental design |
Note: The heavy emphasis on anatomy and physiology reflects the healthcare focus of nursing programs, making this area your highest study priority.
