What is the Exam?

The HESI A2 (Health Education Systems, Inc. Admission Assessment) is a highly standardized entrance exam administered by Elsevier. It is extensively used by university nursing schools and allied health programs across the United States to evaluate the academic readiness of prospective students. This exam matters because it serves as a critical gatekeeper for nursing program admissions. It effectively predicts a student's ability to handle the rigorous, fast-paced coursework of a nursing curriculum and assesses their likelihood of ultimately passing the NCLEX licensure exam.

Exam Format and Passing Score

While the exact length of the official exam depends on which specific modules your chosen nursing program requires, the standard exam format generally follows these parameters:

• Number of Questions: The full, comprehensive exam can contain up to 326 questions. (Note: This premium 2026 practice test PDF is strategically condensed into 140 high-yield questions targeting the most frequently tested concepts).

• Time Limit: Candidates are typically allotted a maximum of 4 to 4.5 hours to complete the official computerized exam.

• Passing Score / Percentage: There is no universal passing grade, as each institution sets its own admission criteria. However, most competitive nursing programs require a minimum composite score of 75% to 80% (often corresponding to a score of 800–850 out of 1000) on all required sections. A score of 90% to 100% (900+) is considered excellent and significantly increases admission chances.

Core Exam Topics / Categories

Nursing programs customize the HESI A2 exam based on their specific prerequisites. Depending on your school's requirements, you will be tested on a combination of the following core categories:

• Basic Math Skills: Fractions, decimals, ratios, proportions, basic algebra, and standard metric/household conversions.

• Reading Comprehension: Extracting main ideas, understanding context, and making logical inferences from health-related reading passages.

• Vocabulary & General Knowledge: Fundamental vocabulary and terminology frequently used in general healthcare and academic environments.

• Grammar: Essential grammatical principles, sentence structure, parts of speech, and written communication skills.

• Anatomy & Physiology: General human physiology, bodily systems, and anatomical terminology.

• Biology: Cellular biology, metabolism, photosynthesis, and basic genetics.

• Chemistry: Atomic structure, the periodic table, chemical equations, and introductory biochemistry.

• Physics: Basic physical principles including motion, energy, and thermodynamics (required by a select few programs).

• Learning & Personality Styles: Brief, unscored assessments designed to identify your individual learning preferences and study habits.
