Question counts, time limits, and what each section tests.
The HESI A2 is delivered section by section, each on its own timer. The table below is the per section format our app's mock exams mirror: the question counts and minutes applicants prepare against. Your program chooses which of these sections you actually sit, and its exam instructions are the authoritative version of the details.
Sitting all seven academic sections adds up to 272 questions across 285 minutes of section timers. Almost nobody sits all seven: the common requirement is math, reading, vocabulary, and grammar, with anatomy and physiology added by many programs and biology or chemistry by fewer.
| Math | 50 questions, 50 minutes |
|---|---|
| Reading | 47 questions, 60 minutes |
| Vocabulary | 50 questions, 50 minutes |
| Grammar | 50 questions, 50 minutes |
| Anatomy & Physiology | 25 questions, 25 minutes |
| Biology | 25 questions, 25 minutes |
| Chemistry | 25 questions, 25 minutes |
| All seven together | 272 questions, 285 minutes |
Every section averages roughly a minute per question, and reading is the only section with meaningful slack. That pace is comfortable if you have practiced at it and brutal if you have not. The practical rule: practice untimed while you are learning a topic, then switch every session to timed once you are two weeks out.
The one minute average also explains the highest value skills: instant unit conversions in math, decoding vocabulary by word parts instead of recall, and reading questions before hunting through the passage. Each one converts seconds saved into questions attempted.
Whether tools like an on screen calculator are provided is part of your program's exam instructions; practice the arithmetic by hand and the answer to that question stops mattering.
Math: fractions, decimals, percents, ratios and proportions, measurement conversions, and dosage style word problems. Reading: comprehension of health related passages, main idea, detail, and inference. Vocabulary: medical word parts and academic vocabulary, in and out of context. Grammar: sentence structure, punctuation, agreement, and commonly confused words.
Anatomy and Physiology: body organization and directional terms, cells and tissues, organ systems, and homeostasis. Biology: cell biology, energy and metabolism, DNA and genetics. Chemistry: atomic structure, bonding, reactions, moles, and acids and bases.
Deeper study advice per section lives in the study guide; you can feel the real question style in the free practice test.
Do I sit all seven HESI A2 sections?
Almost certainly not. Your program picks the sections it requires, most commonly math, reading, vocabulary, and grammar, often plus anatomy and physiology. Check your program's admissions page for the exact list.
Are there breaks between HESI A2 sections?
Break policy is part of your testing center's or program's exam instructions rather than a fixed universal rule, so confirm it when you register. Plan your energy for a multi hour sitting either way.
Is there a personality or learning style part?
Some programs add Elsevier's unscored profile inventories to the sitting. They do not affect your academic scores. Your registration instructions will say whether they are included.
