HESI A2 Exam: The No-Fluff Guide to Getting a Higher Score

If nursing school is the goal, the HESI A2 is one of the gates you need to pass. This guide keeps it simple and practical so you know exactly what the test covers, how it’s scored, and how to study without burning out.

What is the HESI A2?

The HESI Admission Assessment (HESI A2) is a standardized test many nursing programs use to evaluate your academic readiness. Schools choose which sections they require, so your exact test may vary. Most programs include Reading Comprehension, Vocabulary, Grammar, and Math. Some add Biology, Chemistry, Anatomy & Physiology, and sometimes Learning Style and Personality Profile.

Test Format at a Glance

• Question type: Multiple choice
• Common sections: Reading, Vocabulary, Grammar, Math; often A&P, Biology, Chemistry
• Time: Varies by school and section mix
• Delivery: Computer based, usually at a testing center or online with proctoring

Scoring Basics

Each section gets its own percentage score. Many programs set minimums per section rather than one overall cutoff. Aim for the highest possible scores, especially in Math and Reading, since those are widely required.

What Each Core Section Covers

Reading Comprehension
Main ideas, inferences, supporting details, purpose, tone, and understanding charts or passages quickly.

Vocabulary & General Knowledge
Medical and academic terms, prefixes, suffixes, and root words. Knowing word parts builds speed and accuracy.

Grammar
Parts of speech, sentence structure, punctuation, subject–verb agreement, and common usage errors.

Math
Fractions, decimals, ratios, proportions, percentages, basic algebra, measurements, and dosage style word problems.

Science (if required)

• Anatomy & Physiology: Body systems, organ functions, homeostasis.
• Biology: Cells, genetics, metabolism, basic microbiology.
• Chemistry: Atoms, bonds, solutions, pH, equations at a basic level.

How to Build a Focused Study Plan

1. Check your school’s required sections
   Confirm which sections you will take. No wasted effort.
2. Take a quick diagnostic
   Do a short practice set for each required section to find weak spots. Let results guide your plan.
3. Set a realistic schedule
   Study 45–60 minutes per block, 5–6 days a week. Rotate sections. Example:
   • Mon: Reading + Vocab
   • Tue: Math
   • Wed: Grammar
   • Thu: Science
   • Fri: Mixed review + practice questions
   • Sat: Timed mini test
   • Sun: Rest or light flashcards
4. Use active methods
   • Create flashcards for vocab and formulas.
   • Teach a tough concept to a friend out loud.
   • Work problems step by step, then re-work errors.
   • Keep a “missed question” notebook and revisit it twice a week.
5. Simulate the test weekly
   Do one timed session in the same order you will test. Train accuracy first, then speed.

Section-Specific Tips

Reading
Read the questions first to anchor your purpose. Find evidence for every answer choice. Eliminate options that overgeneralize or add facts not in the passage.

Vocabulary
Break words into parts. Build a personal glossary of medical terms and review it daily for 10 minutes.

Grammar
Memorize high-yield rules: subject–verb agreement, comma use, pronoun clarity, parallel structure. Practice rewriting messy sentences into clear ones.

Math
Know conversions, fraction–decimal–percent moves, and proportion setups. Show work neatly. Estimate to catch obvious mistakes.

Science
Sketch simple diagrams of body systems. For chemistry, keep a one-page formula and concept sheet. For biology, connect terms in mini mind maps.

Test-Day Game Plan

• Sleep and hydrate the day before.
• Arrive early with required IDs.
• Pace yourself: mark and skip time-sink questions, then return.
• Double-check math units and answer reasonableness.
• Stay calm: one question does not define the entire test.

Common Pitfalls to Avoid

• Studying every topic equally even when some are not required.
• Cramming only with passive reading.
• Ignoring timing practice until the week of the test.
• Forgetting to review wrong answers and patterns.

FAQs

1) What is a good HESI A2 score?
Many schools look for 75–80% or higher per required section, and competitive programs often prefer scores in the 80s and 90s. Check your program’s posted minimums and aim to exceed them.

2) How long should I study for the HESI A2?
For first-time test takers, 3–6 weeks of consistent study works well for core sections. If you’re adding Science, plan 6–8 weeks with weekly timed practice.

3) Can I retake the HESI A2 if I do poorly?
Most schools allow retakes, often with a waiting period and a limit on attempts per year. Policies vary, so confirm details with your program before scheduling.

4) Is a calculator allowed?
Yes. The testing software typically includes an on-screen basic calculator. Physical calculators are usually not permitted.

5) Do HESI A2 scores expire?
Many programs accept scores for 1–2 years, but this varies by school. If your scores are older, you may need to retest.
