What Is the HESI A2?
The HESI A2 (Health Education Systems Incorporated Admission Assessment) is the primary entrance exam for nursing school admission. Hundreds of nursing programs — BSN, ADN, and LPN — require HESI A2 scores as part of their application. Most programs want a composite score of 75% or higher, with competitive programs requiring 80-85%+.
Unlike the HESI Exit Exam (which is taken at the end of nursing school), the HESI A2 is taken before you get in. A low score can block you from your program of choice entirely. The exam covers up to 8 subjects depending on your school’s requirements — not all schools test all sections.

How to Study for the HESI A2
Buy the Official Elsevier HESI A2 Study Guide
Elsevier publishes the official HESI A2 study guide — it’s written by the same company that makes the exam. This is your primary resource. Work through each required section chapter by chapter. The practice questions at the end of each chapter closely mirror the real exam format.
Prioritize A&P — It’s the Highest-Yield Section
Anatomy and Physiology is the section most nursing programs require AND the one most students struggle with. Focus on: cardiovascular system (heart chambers, valves, blood flow), respiratory (gas exchange, lung volumes), renal (nephron function, filtration), and endocrine (major hormones and their target organs). These topics appear most frequently.
Math: Master Dosage Calculations and Ratios
HESI A2 Math heavily tests dosage and medication calculations, ratio/proportion problems, and unit conversions. Practice these until they’re automatic: converting mg to mcg, mL to L, calculating drip rates, and solving proportion problems. These are the most commonly missed questions.
Vocabulary: Study Medical Prefixes, Suffixes, and Roots
HESI A2 Vocabulary heavily tests medical terminology. If you know common prefixes (brady-, tachy-, hyper-, hypo-), suffixes (-itis, -ectomy, -plasty, -oscopy), and roots (cardio, neuro, hepato, nephro), you can figure out words you’ve never seen before. This is the most efficient vocabulary study strategy.
Take Full Practice Tests for Every Required Section
Study section by section, then take full-length practice tests under timed conditions. Elsevier’s online practice exams are the closest to the real thing. Your practice scores predict your real score. If you’re consistently below your target, identify your weakest subsections and drill those specifically.
