ATI TEAS 7 Course Notes

High-yield TEAS math. Build the equation before calculating, keep units attached, and estimate before choosing an answer. For fractions, decimals, percents, proportions, ratios, and percent change, the setup is usually more important than difficult arithmetic. Use the on-screen calculator strategically, but do not let it replace number sense.

• Using 25 instead of 0.25 for 25%.

• Write the relationship first; calculate second.

The most heavily tested science subcontent is A&P. Study pathways and structure-function relationships rather than isolated labels. Be able to trace air, blood, food, nerve signals, hormones, filtrate/urine, and immune responses and explain how organ systems maintain homeostasis.

• Calling pulmonary arteries oxygenated because they are arteries.

• Trace pathways from start to finish out loud.

This section is data + geometry + conversions. Read the visual before calculating: identify title, variables, units, scale, and legend. For statistics, know what each measure tells you and how outliers affect it. For geometry and conversion problems, write the formula or conversion factor first and keep units visible.

• Reading the bar height but ignoring that the axis starts above zero.

• Visual first: title → axes → units → legend → scale.

Read for what the passage actually says. A strong summary keeps the central idea and essential support while dropping examples and minor detail. An inference is not a guess—it is the conclusion best supported by textual evidence. Directions and visuals are tested literally, so labels, sequence words, and qualifiers matter.

• Choosing the most interesting detail as the main idea.

• Ask: 'What is this mostly about, and what is the author saying about it?'

This is synthesis reading. The core pattern is CLAIM → EVIDENCE → REASONING. Decide what each source contributes, whether the evidence actually supports the claim, and how multiple sources agree, disagree, or fill different parts of the same picture.

• Treating a claim as evidence for itself.

• Label mentally: claim, evidence, reasoning.

This is the mechanics section. Read the entire sentence because punctuation and spelling depend on meaning and structure. Identify independent clauses first; then decide how they should be joined. Most traps are fragments, run-ons, comma splices, apostrophe errors, or agreement problems.

• Using an apostrophe to make a word plural.

• Find the subject and verb before judging agreement.

Knowledge of Language is about effective writing, not merely error hunting. Choose wording and organization that make the writer's purpose clearest for the intended audience. Watch pronoun references, tense shifts, modifiers, redundancy, paragraph order, transitions, and tone.

• Choosing the grammatically correct sentence that does not fit the audience.

• Ask: Who is the audience? What is the purpose?

Know which writing stage solves which problem. Revision changes ideas, organization, clarity, and support; editing/proofreading correct mechanics and final surface errors. For vocabulary, break unfamiliar words into meaningful parts, then verify the likely meaning against the sentence context.

• Calling grammar correction 'revision' when the issue is editing.

• Big change = revision; surface correction = editing/proofreading.

Craft and Structure asks how the author built the message. Distinguish verifiable statements from judgments, identify slanted language, use context rather than a memorized dictionary definition, and separate purpose (why the author wrote) from point of view/perspective (the position or lens the author brings).

• Calling every strong statement biased.

• Fact? Ask whether it can be verified.

Biology is mostly structure-function and information flow. Know what organelles do, how substances cross membranes, how DNA information becomes protein, how Mendelian inheritance predicts probability, and how the four major biomolecule classes differ.

• Confusing ribosomes with mitochondria.

• Organelles: memorize one primary job each.

Scientific reasoning rewards disciplined use of evidence. Identify what was changed, what was measured, what was held constant, and whether the data actually support the conclusion. Repeated consistent results improve reliability; good design and control of confounders improve confidence that the investigation measures what it intends to measure.

• Confusing the measured outcome with the manipulated variable.

• Ask four questions: What changed? What was measured? What stayed constant? What do the data show?

Keep TEAS chemistry fundamental. Focus on atoms, matter, reactions, reaction-rate conditions, solutions, and acids/bases. The review draft went beyond the ATI outline with topics such as colligative properties and detailed equilibrium calculations; those are not necessary for a quick-pass TEAS 7 sheet.

• Using mass number as the number of neutrons.

• Atomic number = protons. Neutrons = mass − atomic number.
