About this exam

The HESI A2 Anatomy & Physiology (A&P) exam is a subject-area admissions assessment used by many nursing and health-science programs to gauge whether applicants have the foundational biology knowledge needed for clinical coursework. It is aimed at prospective nursing students and other health-program applicants who must demonstrate readiness before or during admission, and it is typically one section within the broader HESI A2 battery rather than a stand-alone license. The A&P section tests core body-system content: terminology and body organization, the integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, respiratory, digestive, urinary, and reproductive systems, plus fluid and electrolyte basics. Expect identification of structures, function-to-structure matching, and applied reasoning about how systems interact. Preparation works best in layers: start with a broad review of each system's anatomy and function, then drill high-yield topics such as cell transport, blood flow through the heart, gas exchange, nephron function, and hormone actions. Use labeled diagrams, spaced repetition for terminology, and short practice sets to find weak systems, then revisit those systems with focused reading. Confirm with your specific program which sections it requires, how scores are weighted, and whether a retake is permitted, since policies vary by institution.

What you'll study

Common questions

About HESI A2 A&P preparation

What does the Anatomy & Physiology section actually test?

It tests structure and function across the major body systems, plus basic terminology, body organization, and cell-level concepts such as transport and metabolism. Questions tend to ask you to identify structures, match organs to functions, and reason about how systems interact rather than perform calculations.

How long is the exam and how many questions are there?

Those figures are set by the exam publisher and are not confirmed here, so treat any specific number you hear as unverified until your program or the official publisher materials state it. Check your admissions packet for the current section length and item count before you plan timing practice.

Is the A&P section hard?

Most candidates find it moderately demanding because it rewards memorization of terminology plus applied reasoning. The content is broad rather than deeply mathematical. Difficulty usually comes from volume, not trick questions, so spaced review across all systems beats last-minute cramming of one or two favorite topics.

Can I retake it if my score is low?

Retake rules are set by the school or program that requires the exam, not by this page. Some programs allow one retake after a waiting period; others limit attempts or average scores. Ask your admissions office in writing before you sit the exam so you know your options.

What score do I need to pass?

There is no single universal passing score published here. Programs set their own minimums or use the score competitively alongside GPA and other admission factors. Ask your target program directly what A&P score it expects and whether a higher score improves your ranking.

In what order should I study the body systems?

A practical order is terminology and body organization first, then cells and tissues, then systems in a logical sequence such as integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, respiratory, digestive, and urinary. End with reproductive and fluid/electrolyte content, then run mixed practice sets so recall is not tied to one topic.

What are the most common mistakes candidates make?

Cramming terminology without linking it to function, skipping systems they find boring, and never practicing mixed questions under time pressure. Another frequent error is studying from unverified question sets that teach outdated or wrong facts. Verify content against a current anatomy textbook and your program's objectives.

How far in advance should I start preparing?

Give yourself several weeks of consistent short sessions rather than a few long ones. A common approach is four to eight weeks, depending on how recently you took anatomy. Build in at least one full mixed review near the end so you can identify weak systems while there is still time to fix them.

Does this page come from the exam's publisher?

No. This is independent study material written for candidates searching for the exam. It is not affiliated with, endorsed by, or produced by the exam publisher or any nursing program. Always confirm format, timing, scoring, and retake policy with your school and the publisher's current official materials.
