TEAS 7 Study Guide

This 6-week TEAS 7 study guide is structured around the exam's actual question distribution. Science comes first because it carries 50 of 170 questions — more than any other section — and has the widest difficulty range. Students who build a strong Science foundation in weeks 1\u20133 almost always achieve a competitive composite score by test day.

“The most common TEAS 7 study mistake is starting with Math or Reading. Science carries 50 questions — it deserves the first three weeks.”

The 6-week TEAS 7 study plan

1Baseline + Science A&P I
Take a full-length diagnostic practice test to establish starting section scores. Then begin Human Anatomy and Physiology: cardiovascular system (heart anatomy, cardiac cycle, blood pressure), respiratory system (mechanics of breathing, gas exchange), and renal system (nephron function, fluid balance). A&P is the highest-weighted topic on the TEAS 7 Science section.
2Science A&P II + Biology
Continue A&P: nervous system (neurons, synaptic transmission, CNS vs. PNS), endocrine system (hormones, feedback loops, major glands), immune system (innate vs. adaptive, antibodies). Then move to Biology: cell structure and function, cell division (mitosis and meiosis), genetics (Mendelian inheritance, DNA structure, protein synthesis).
3Science Chemistry + Scientific Reasoning
Cover Chemistry: atomic structure, the periodic table, chemical bonding (ionic, covalent), chemical reactions and balancing equations, acids and bases, solutions and concentration. Then Scientific Reasoning: experimental design, interpreting data tables and graphs, identifying variables, drawing conclusions from evidence.
4Mathematics
Cover all Math topics systematically: arithmetic (fractions, decimals, percentages, ratios, proportions), algebra (solving equations, inequalities, word problems), measurement and data (unit conversions, reading tables and charts), statistics and geometry. Drill 30–40 timed questions per day. The calculator is permitted — practice using it efficiently.
5Reading + English + Practice Exam
Reading: main idea identification, inference questions, author purpose and tone, vocabulary in context, interpreting visual information. English and Language Usage: grammar rules (subject-verb agreement, pronoun case, modifier placement), punctuation, sentence structure, spelling conventions. Take a second full-length timed practice exam at the end of the week.
6Weak areas + Final exam
Return to your two lowest-scoring sections from the week 5 practice exam. Complete targeted practice questions in those areas only. Take a final full-length timed practice exam in the first half of week 6. Review errors only — do not introduce new content. Stop active studying 24 hours before your exam.

Study guide questions

How long should I study for the TEAS 7?
Most students need 6–12 weeks at 10–15 hours per week. Students with recent college-level Science (Biology, Chemistry, A&P) may need only 6 weeks. Students who have not taken science in several years should plan for 10–12 weeks. The key variable is how strong your Science foundation is — everything else on the TEAS 7 can be prepared for more quickly.
What should I study first for the TEAS 7?
Science first — always. It has the most questions (50 of 170) and the widest difficulty range. Human Anatomy and Physiology is the single most important topic. Students who master A&P typically achieve competitive composite scores even with average performance elsewhere. Starting with Math or Reading first is the most common TEAS 7 study mistake.
How many practice tests should I take for the TEAS 7?
At minimum, take 2 full-length timed practice exams: one at the start to establish your baseline, and one in the final week to simulate test day. More is better if time allows. Each practice exam should be taken under realistic conditions — timed, no notes, no interruptions.
Is the official ATI TEAS study guide worth buying?
The official ATI study materials are useful for understanding the exam format and question style, since ATI makes the TEAS. However, the official guide is often criticized for limited explanations on wrong answers. Many students use ATI for format familiarity and a platform like StudyBuddy for content depth and AI-powered weak-area targeting.
