TEAS 7 Science Practice

What this section actually tests

Science is the longest section on the clock: 50 questions in 60 minutes, with 6 unscored pilot items. Questions are drawn from four content areas. Human anatomy and physiology is the largest, covering body systems and how they work together. Biology covers cells, genetics and the basic processes of living things. Chemistry covers matter, atomic structure, reactions and solutions. Scientific reasoning covers how experiments are designed and how data is read - variables, controls and drawing conclusions from results.

Question types you will meet

• Body-system function - identify the role of an organ or system, or the sequence of a process such as blood flow or digestion.
• Cell and genetics questions - match structures to functions, or work with inheritance patterns.
• Chemistry fundamentals - recognise atomic structure, chemical bonds, reaction types or the properties of solutions.
• Experimental design - identify the independent and dependent variables, or spot the control.
• Data and results - interpret a table or graph from a described experiment and reach a supported conclusion.
• Ordered response - place the steps of a process into the correct sequence.

Where marks are lost

• Learning isolated facts without the connections between them. The exam often asks how two systems or processes relate rather than for a single definition.
• Confusing similar structures or terms - arteries and veins, mitosis and meiosis, atoms and ions - because the definitions were memorised as one line each.
• Misreading an experiment question as a recall question and answering with a remembered fact instead of the data shown.
• Spending equal time on every area when anatomy and physiology carries the greatest share of scored items.

How to use these ten tests

Because the content areas are unevenly weighted, use a first test to find your weak area rather than to chase a score. Every question carries an explanation, so read it for each item you missed and sort your errors by content area. Then work a fresh test with the same attention to your weakest area, and retake earlier tests freely to check that a topic has actually stuck - a repeated pass on a set you have seen before is only useful if the reasoning feels immediate.
