TEAS 7 Science Topics and Study Priorities
TEAS 7 Science becomes more manageable when you organize facts into systems, processes, and cause-and-effect relationships. Use the current ATI outline as your authoritative scope, then use this guide to structure your review.
Prioritize anatomy and physiology
Study each body system through four questions: What are its major structures? What does each structure do? How is the system regulated? How does it interact with other systems? This approach makes isolated terms easier to retrieve in a scenario.
- Cardiovascular and respiratory exchange
- Digestive absorption and metabolism
- Nervous and endocrine control
- Urinary balance and waste removal
- Immune defense, reproduction, and musculoskeletal function
Understand biology as a set of processes
Connect cell structures to their functions, then trace information and energy through the cell. Practise genetics with simple crosses and interpret how DNA, genes, chromosomes, and proteins relate.
- Cell structure and transport
- DNA, RNA, and protein synthesis
- Mitosis, meiosis, and inheritance
- Macromolecules and enzymes
- Microorganisms and biological organization
Make chemistry concrete
Focus on particle behavior and observable outcomes. Explain how atomic structure affects bonding, how reactions rearrange matter, and how concentration, temperature, or pH changes a system. Include calculation practice where units guide the setup.
Practise scientific reasoning
Identify variables, controls, hypotheses, trends, and conclusions in experiments. Separate what the data supports from what merely sounds plausible. When reading a table or graph, state the relationship in words before selecting an answer.
- Independent and dependent variables
- Control groups and constants
- Measurement quality and sources of error
- Tables, graphs, and experimental conclusions
Use a high-retention review method
After reviewing a topic, close your notes and draw the process, teach it aloud, or answer a fresh question. Add only missed relationships to your error log. Revisit them after two days, one week, and during mixed practice.
