Kala's TEAS Study Hub

Study guide — the short version of everything

These are the high-yield topics per section. Work the guide, then drill the same section under Practice Tests.

📖 Reading

• Main idea vs. detail: the main idea covers the whole passage; details only cover a piece. If an answer choice is true but narrow, it's a detail, not the main idea.
• Inference: pick the answer the passage supports, not one that's merely possible. Every correct inference has evidence in the text.
• Author's purpose & tone: to inform, persuade, entertain, or describe. Watch charged words — they leak the author's bias.
• Craft: know text structures (cause/effect, compare/contrast, sequence, problem/solution) and what headings, bold terms, and captions signal.
• Practical texts: practice following multi-step directions exactly, reading a chart/table, and pulling requirements out of a job posting or memo.

➗ Mathematics

• Percents: part = percent × whole. Percent change = (new − old) ÷ old. Convert fluently: fraction ↔ decimal ↔ percent.
• Ratios & proportions: set up equal fractions and cross-multiply — this is also the dosage-calculation engine (dose ordered ÷ dose on hand × quantity).
• Conversions: metric ladder (kilo → base → milli = steps of 1,000; 1 kg = 2.2 lb, 1 in = 2.54 cm, 1 L = 1,000 mL, 30 mL ≈ 1 fl oz).
• Algebra: solve one- and two-step equations; inequalities flip the sign when you multiply/divide by a negative.
• Data: mean (average), median (middle), mode (most often), range (max − min). Read bar/line/pie graphs by their axes and legends first.
• Geometry: area/perimeter of rectangles and triangles, area/circumference of circles (πr², 2πr), volume of a box (l×w×h).

🔬 Science — Anatomy & Physiology first

• Directional terms: anterior/posterior, superior/inferior, medial/lateral, proximal/distal; planes: sagittal, frontal (coronal), transverse.
• Cardiovascular: blood flow path (body → right atrium → right ventricle → lungs → left atrium → left ventricle → body), heart valves in order, arteries carry blood away, veins toward.
• Respiratory: gas exchange in the alveoli; diaphragm drives breathing; medulla sets the rate from CO₂ levels.
• Nervous: neuron parts, CNS vs PNS, sympathetic = fight-or-flight, parasympathetic = rest-and-digest.
• Endocrine: master gland = pituitary; insulin/glucagon from the pancreas regulate blood sugar; negative feedback runs most systems.
• Digestive & urinary: path of food; the nephron filters blood — glomerulus → tubules; kidneys regulate water, salts, and pH.
• Biology: organelles (mitochondria = ATP), DNA → RNA → protein, mitosis (growth, identical) vs meiosis (gametes, half), Punnett squares for dominant/recessive traits.
• Chemistry basics: atom structure, pH scale (below 7 acid, above 7 base), states of matter, solutions and concentration.
• Scientific reasoning: independent vs dependent variable, controls, and why sample size and repetition matter.

✏️ English & Language Usage

• Punctuation: commas in lists and after introductions; apostrophes show possession or contractions, never plurals; quotation marks for direct speech.
• Agreement: subject-verb and pronoun-antecedent must match in number. Watch collective nouns and "each/everyone" (singular).
• Sentence sense: fragments lack a subject or complete verb; run-ons need a period, semicolon, or comma + conjunction.
• Homophones: their/there/they're, its/it's, affect/effect, then/than, to/too/two.
• Medical word parts: cardio- (heart), neuro- (nerve), hepat- (liver), nephr- (kidney), hyper- (over), hypo- (under), -itis (inflammation), -ectomy (removal), -ology (study of), brady- (slow), tachy- (fast). These pay off on the TEAS and in nursing school.

Practice tests

Every question is original, written to the real TEAS 7 blueprint, with an explanation for every answer. Two ways to train:

Section drills

One section at a time, real question count and real time limit. Best for most study days.

Full mock exam

All 170 questions, 209 minutes, sections in real order with their own clocks — the full dress rehearsal. Set aside about 3½ hours.

Start the full mock exam

In drill mode you can check each answer as you go. In the mock, answers lock section by section — just like the real thing, there's no going back to a finished section.

A 6-week study plan (bend it to your test date)

Built for someone working full-time: short weekday sessions beat weekend marathons. About 45–60 minutes a day, one longer session a week. Everything in the “Do this” column is a link — tap it and it takes you straight there.

Week	Focus	Do this
1	Baseline	Take the free NurseHub or Mometrix 170-question diagnostic. Note your two weakest sections — they get double time from here on.
2	Science I	A&P systems: cardiovascular, respiratory, nervous. Guide + Science drill in this hub. Start the 3D anatomy tool tours.
3	Math	Percents, ratios/proportions, conversions, dosage math until they're automatic. Math drill twice.
4	Reading + English	Passage strategy (read questions first), grammar rules, medical word parts. Do the Reading drill and the English drill.
5	Science II + weak spots	Remaining A&P systems, biology, chemistry. Re-drill week-1 weaknesses. Take ATI Practice Test A if you have it.
6	Dress rehearsal	Full mock in this hub (or ATI Practice Test B) under real timing. Review every miss. Light study only the last two days.

Test-week rules: sleep beats cramming; eat before a 3½-hour test; use the 10-minute break after Math to actually stand up and reset. If a question stalls you past ~90 seconds, mark it, move on, come back.

Already took APHY 101 or deep into it? Compress weeks 2 and 5 — the science is partly banked. Weak in math after years away from it? Give week 3 a twin.

Resources — free first

Free stack ($0)

• NurseHub free practice test — full 170-question diagnostic (nursehub.com — beware the lookalike "nursehub.online", it's a scam selling "real questions").
• Mometrix free TEAS practice test — second full-length check mid-way through studying.
• Union Test Prep — free TEAS study guides section by section.
• Khan Academy — free A&P and math lessons; also linked from Ivy Tech's own library guide.
• Pocket Prep app — free daily TEAS questions on your phone for spare minutes.
• Ivy Tech Indianapolis library — Anatomage Table: a life-size 3D cadaver dissection table, free for students during library hours. Best hands-on anatomy you'll get anywhere.

Worth paying for (when Devon says go)

• ATI Practice Tests A & B package — $69: the only practice written by the test-maker. A early as a diagnostic, B last as the dress rehearsal.
• NurseHub — $30/mo or Smart Edition — $29.99/mo (video explanation for every question — the most listenable option).
• ATI Comprehensive — $199: includes SmartPrep's adaptive study plan, the strongest Proficient→Advanced engine, if the budget stretches.
• Visible Body Suite — $34.99/yr: the 3D anatomy + physiology pick (phone and browser). Skip Kaplan's TEAS book — it's TEAS 6-era (2019).

Tell your sexy hubby 🪽

This app is yours, Kala. Want something added, changed, or fixed — a topic that's missing, a lesson you'd love to listen to, colors, anything? Write it here and it goes straight to your hubby's inbox crew — Wren reads every word and builds what you ask for (yes, Devon set this up, and yes, he picked the name of this page). Small changes get made; big ideas get brought straight to the sexy hubby himself.

What this button is actually for: anything about this app. A topic you want covered, a quiz or lesson you'd like added, something that looks wrong, a color you hate, a feature you wish existed — if it's about the app, this is the button. Your note lands with Wren, who built this thing with Devon and Sunny, and small changes usually get made the same day. (For grocery lists and actual husband duties, use the real hubby. 😄)

What kind of feedback is it?

💌 Send to your sexy hubby

Tapping Send opens your email app with the message already written — just press send there. No account, no form, no fuss. You can also always just tell Devon and he'll pass it on.

Anatomy 3D — tap a structure

Real 3D organs, built from medical scan data. Pick an organ, drag to spin it, pinch or scroll to zoom, and tap any part to learn its name. In Test mode I'll name a structure — you tap it.

Pick an organ above to load its 3D model.

Physiology — how the body works

Anatomy is the parts; physiology is the story of what they do. Play with each one — these four ideas carry a huge share of TEAS Science and your A&P classes.

🫀 Cardiac Cycle

Step through one heartbeat — watch which chambers squeeze and which valves are open — then take the 5-question recall check.

Open the Cardiac Cycle →

⚡ Action Potential

Step through a neuron action potential — membrane voltage, threshold, and which ion gates are open at each stage — with a recall check at the end.

Open Action Potential →

🍞 Blood Glucose Feedback

Pick a cause, then step through the negative feedback loop — insulin and glucagon — that brings blood glucose back to normal. Recall check included.

Open Blood Glucose Feedback →

🫁 Breathing Mechanics

Step through one breath — the diaphragm, chest volume, and pressure in the lungs compared to the air outside — then check what stuck.

Open Breathing Mechanics →

🎧 Listen — audio lessons

Lessons read aloud by your device's voice — made for the car, the couch, and the closing shift. Tap a lesson and listen; finished ones get a ✓ and a gold border.

Headphones + a walk = a study session. If the voice sounds robotic, your phone's text-to-speech settings can swap in a warmer one.
