ATI TEAS 7 Science: what ATI tests, how the 60-minute block works, and how to prepare

How Science fits the full ATI TEAS 7

The live exam is 170 questions · 209 minutes in a fixed order. Science does not share time with any other section.

• Reading, 45 questions · 55 minutes
• Mathematics, 38 questions · 57 minutes
• Science, 50 questions · 60 minutes (you are here)
• English and Language Usage, 37 questions · 37 minutes

ATI’s three Science reporting areas

TEAS 7 Science content is reported under three ATI categories. A single item can touch more than one, for example a blood-pressure graph tests scientific reasoning and cardiovascular A&P.

High-yield topics for TEAS 7 Science

Anatomy & physiology (ATI emphasis)

• Directional terms, planes, cavities, and major organ locations
• Skeletal and muscular basics, including joint movement and contraction language
• Cardiovascular pathway: chambers, valves, pulmonary vs. systemic flow, pulse and pressure ideas
• Respiratory mechanics, gas exchange, and ventilation vs. perfusion
• Digestive tract order, absorption, and enzyme roles at overview depth
• Urinary: nephron, filtration, reabsorption, and fluid balance cues
• Endocrine feedback (for example insulin/glucagon, ADH)
• Nervous: CNS vs. PNS, reflex arc, sympathetic vs. parasympathetic responses
• Immune: innate vs. adaptive, inflammation, vaccination concept

Life science on TEAS 7

• Organelles, transport, mitosis vs. meiosis
• Central dogma and basic inheritance vocabulary
• Punnett-square style probability (not full genetics coursework)
• Photosynthesis and cellular respiration inputs and outputs
• Ecology: populations, limiting factors, energy in ecosystems

Chemistry & physics at TEAS difficulty

• Atoms, periodic trends, ionic vs. covalent bonding, polarity and water
• pH, acids and bases, simple reaction language
• Solutions, concentration terms, and unit sense (no calculator on TEAS)
• Force, motion, work, simple machines, and energy forms

Scientific method & data on this section

• Independent vs. dependent variables and control groups
• Interpreting line graphs, bar charts, and short experiment summaries
• Correlation vs. causation and overstated conclusions
• Metric prefixes and conversions when a science item embeds numeric reasoning

What happens when you sit ATI TEAS 7 Science

After Mathematics you get a 10-minute break, then Science begins on a fresh 60-minute clock. Time from Reading or Math does not carry over.

• Expect 50 Science items on the scored TEAS 7 form, plus additional unscored pretest items mixed through the full exam. ATI does not label which are pretest, so answer every Science item as if it counts.
• Item types are multiple choice with four options; you may see short passages with follow-up questions or standalone stems.
• No calculator is permitted on TEAS 7 Science; numbers are chosen for mental math or estimation.
• Diagrams (heart, nephron, cell, etc.) and experiment tables are common; read labels before the answer choices.
• You can move within the Science section until you submit it; there is no penalty for guessing on TEAS.

Strategies that match ATI TEAS 7 Science items

1. Study by organ system the way ATI blends A&P (cardiovascular + related hormones in one block).
2. Sketch pathways (blood flow, nephron, reflex arc). TEAS often asks “what happens next if…”
3. Link term → function → clue (for example medulla and filtration) instead of isolated vocabulary lists.
4. Narrate graphs in one sentence before you look at distractors.
5. Eliminate answers that break physiology or contradict the passage, then guess if needed.

Mistakes we see on TEAS 7 Science prep

• Drilling college organic chemistry while skipping integrated A&P scenarios ATI actually asks.
• Memorizing bone lists without joint or muscle action context.
• Treating reasoning-heavy Science items as “Reading” and leaving easy Science points on the table.
• Losing the section clock on one diagram when several one-step recall items were still open.
• Using a professor’s chapter order instead of ATI’s mixed reporting categories.

Four-week plan aimed at TEAS 7 Science

Week 1: Body organization plus chemistry/physics refresh aligned to TEAS (atoms, bonds, pH, units). Short mixed Science-style sets daily.

Week 2: Cardiovascular, respiratory, and fluid balance; finish each day with one experiment-style passage.

Week 3: Digestive, urinary, endocrine, nervous, and immune topics; draw pathways every other day.

Week 4: Full 60-minute Science blocks using the 5 ATI TEAS 7 Science Exams quizzes on this page (213 practice questions) ; review every missed rationale the same day.
