HESI A2 Study Schedule: Your Complete Week-by-Week Plan
The HESI A2 (Health Education Systems Inc. Admission Assessment) is your gateway to nursing school — and your score directly affects your chances of admission. Unlike most exams where you simply pass or fail, nursing programs rank applicants by HESI A2 score. A higher score means a better chance of getting in.
This guide gives you a structured, day-by-day study schedule based on your available timeline. Whether you have 2 weeks or 8 weeks, there's a plan here that works.
HESI A2 At a Glance
The HESI A2 is modular — each nursing program selects which subtests you must take. The table below reflects the full set of available subtests; you will likely take 4–7 of them depending on your school.
| Subtest | Scored Questions | Total Items | Time Limit | Topics |
|---|---|---|---|---|
| Math | 50 | 55 | 50 min | Fractions, ratios, proportions, conversions, Roman numerals, basic algebra |
| Reading Comprehension | 50 | 55 | 60 min | Main idea, inference, supporting details, author's purpose |
| Vocabulary | 50 | 55 | 50 min | Medical/academic terms, context clues, commonly confused words |
| Grammar | 50 | 55 | 50 min | Parts of speech, subject-verb agreement, punctuation, sentence structure |
| Anatomy & Physiology | 25 | 30 | 25–30 min | Body systems, structures, functions, terminology |
| Biology | 25 | 30 | 25 min | Cells, metabolism, DNA, photosynthesis, cellular respiration |
| Chemistry | 25 | 30 | 25 min | Matter, periodic table, bonding, reactions, acids/bases |
| Physics | 25 | 30 | 50 min | Not required by most programs; offered at some schools |
| Critical Thinking | 30 | 30 | 25 min | Optional; scored separately on a different scale |
Total if all subtests taken: ~335 questions, 4–5.5 hours. Most students take 4–7 subtests and finish in 3–4.5 hours. Five unscored pilot items are embedded in each academic subtest.

How Long Should You Study for the HESI A2?
The answer depends on three factors:
| Factor | Less Time Needed | More Time Needed |
|---|---|---|
| Science background | Recent A&P and Biology courses | Haven't taken science in 2+ years |
| Sections required | 4 core sections (Math, Reading, Vocab, Grammar) | Up to 9 sections (incl. A&P, Biology, Chemistry, Physics, Critical Thinking) |
| Target score | 75% (minimum for most programs) | 90%+ (competitive programs) |
Recommended Study Timelines
| Timeline | Best For | Daily Commitment |
|---|---|---|
| 4 weeks | Students who recently completed prerequisite courses and need 4 core sections only | 2–3 hours/day |
| 6 weeks | Most students; good balance of depth and urgency | 1.5–2 hours/day |
| 8 weeks | Students who need up to 9 sections or haven't studied science recently | 1–1.5 hours/day |
| 12 weeks | Working students with limited daily time | 45 min–1 hour/day |
Most successful students study for 6–8 weeks with 1.5–2 hours of daily study. This is the sweet spot for thorough preparation without burnout.
Per-Section Study-Time Budget
If you're planning a 6-week schedule (roughly 75–90 total hours), here's how to divide your time across subtests. Adjust based on your diagnostic results — weak areas get more time.
| Subtest | Recommended Hours | % of Total | Priority |
|---|---|---|---|
| Anatomy & Physiology | 18–22 hrs | ~25% | Highest — broadest content, hardest for most students |
| Math | 12–15 hrs | ~17% | High — fastest gains if you drill conversions and word problems |
| Reading Comprehension | 10–12 hrs | ~14% | Medium — improve via timed passage practice |
| Vocabulary | 10–12 hrs | ~14% | Medium — flashcard-heavy, steady daily reps |
| Grammar | 8–10 hrs | ~11% | Medium — rule-based, quick to master |
| Biology | 8–10 hrs | ~11% | Medium — if required |
| Chemistry | 6–8 hrs | ~8% | Lower — only if required |
| Physics | 4–6 hrs | ~6% | Lowest — only if required |
| Critical Thinking | 3–5 hrs | ~5% | Optional — familiarize with format |
Rule of thumb: Spend 50% of your time on your two weakest subtests and 25% on science. The remaining 25% goes to maintaining your strongest areas.
Step 1: Take a Diagnostic Test First
Before you pick a schedule, you need to know where you stand. Spend your first study session on a diagnostic assessment:
- Take a practice test covering all your required sections
- Score each section separately
- Rank your sections from weakest to strongest
- Allocate more study time to your weakest areas
Scoring Targets by Program Competitiveness
| Program Type | Target Composite Score | Score Interpretation |
|---|---|---|
| Open enrollment/community college | 75–80% | Minimum acceptable |
| Moderately competitive BSN | 80–85% | Solid application |
| Highly competitive BSN | 85–90% | Strong application |
| Accelerated BSN / Direct-entry MSN | 90%+ | Very competitive |

The 4-Week Accelerated Schedule
For students who recently completed prerequisites and need only core sections:
| Week | Focus | Daily Time |
|---|---|---|
| Week 1 | Math + Vocabulary (fundamentals) | 2–3 hours |
| Week 2 | Grammar + Reading Comprehension | 2–3 hours |
| Week 3 | A&P + Biology (if required) | 2–3 hours |
| Week 4 | Full practice exams + weak area review | 2–3 hours |
Warning: The 4-week schedule is only recommended if you scored 70%+ on a diagnostic test without any preparation. If your diagnostic score is below 70%, use the 6-week or 8-week schedule.
The 2-Week Crash Schedule
Only attempt a 2-week plan if you recently completed A&P and Biology prerequisites, scored 75%+ on a diagnostic covering all required sections, and need 4 or fewer core sections. You will study 3–4 hours daily — this is intense and not ideal for most students.
| Day | Focus | Time | Activities |
|---|---|---|---|
| Mon–Tue | Math fundamentals + conversions | 3 hrs/day | Drill fractions, ratios, percentages, Roman numerals, metric/household conversions |
| Wed–Thu | Vocabulary + Grammar | 3 hrs/day | 100+ flashcards, grammar rule sheets, error-identification drills |
| Fri–Sat | Reading Comprehension + (A&P if required) | 3.5 hrs/day | Timed passages, main idea/inference practice; A&P system overview |
| Sun (Wk 1) | Full-length practice exam | 3 hrs | Simulate test conditions, score each section |
| Mon–Tue (Wk 2) | Weak-area deep dives | 3.5 hrs/day | Target the two lowest diagnostic/practice scores |
| Wed–Thu | Mixed practice + second full exam | 3.5 hrs/day | Randomized question sets, second timed practice test |
| Fri | Light review + logistics | 2 hrs | Formula sheet, flashcards, confirm testing location/ID |
| Sat | REST — no studying | 0 | Sleep 7–8 hours, prepare mentally |
| Sun | EXAM DAY | — | Arrive early, confident |
Honest caveat: A 2-week plan risks under-preparing for science sections. If your program requires A&P, Biology, or Chemistry and you haven't taken those courses recently, extend to at least 4 weeks.
The 8-Week Relaxed Schedule
For working students or those who prefer a gentler pace:
| Week | Focus | Daily Time |
|---|---|---|
| Week 1 | Math fundamentals | 60–75 min |
| Week 2 | Vocabulary + Grammar | 60–75 min |
| Week 3 | Reading Comprehension | 60–75 min |
| Week 4 | Anatomy & Physiology (Part 1) | 60–75 min |
| Week 5 | Anatomy & Physiology (Part 2) | 60–75 min |
| Week 6 | Biology + Chemistry (if needed) | 60–75 min |
| Week 7 | Full practice exams + gap analysis | 75–90 min |
| Week 8 | Final review + weak area focus + rest | 60 min, then taper |
Section-by-Section Scoring Tips
Math (Most Improved Section for Most Students)
- Memorize conversions: 1 kg = 2.2 lbs, 1 inch = 2.54 cm, 1 cup = 8 oz
- Practice word problems daily — the HESI presents math as healthcare scenarios
- Use the on-screen calculator wisely — it's basic (four-function only)
- Roman numerals appear — know I through X minimum (some questions use them for medication doses)
Reading Comprehension
- Read the questions first, then the passage — you'll know what to look for
- Focus on main idea questions — they're the most common type
- Healthcare passages are common — practice with scientific articles
- Don't bring outside knowledge — answer based only on what the passage states
Vocabulary
- Academic definitions, not colloquial — the HESI tests formal/clinical definitions
- Learn word parts: If you know 50 common prefixes, suffixes, and roots, you can decode hundreds of words
- Context clue strategy: Even if you don't know a word, the surrounding sentence often reveals the meaning
- Focus on commonly confused words: affect/effect, complement/compliment, discrete/discreet
Grammar
- Subject-verb agreement is the #1 tested concept
- Know your comma rules — commas before conjunctions in compound sentences, commas after introductory phrases
- Commonly confused: their/there/they're, its/it's, who's/whose, your/you're
- Sentence types: simple, compound, complex — know the difference
Anatomy & Physiology
- Study general concepts, not minutiae — the HESI tests understanding, not memorization of every bone name
- Focus on how systems interact — How does the cardiovascular system support the respiratory system? How do hormones affect organ function?
- Know the basics of each system: main organs, primary functions, common disorders
- Organ functions > organ locations for most HESI questions
Biology
- Cell structure is high-yield — know organelles and their functions
- DNA/RNA basics — replication, transcription, translation (the central dogma)
- Photosynthesis vs. cellular respiration — inputs, outputs, where each occurs
- Genetics fundamentals — dominant/recessive, Punnett squares, phenotype vs. genotype
What to Expect on HESI A2 Exam Day
| Detail | Info |
|---|---|
| Format | Computer-based, proctored |
| Location | Your nursing school's testing center (not Pearson VUE) |
| Sections | Determined by your program (up to 9 subtests) |

| Cost | $40–$100 depending on school and number of sections |
School Variability: Why You Must Check Your Program's Policy
The HESI A2 is not a standardized single test — it's a modular exam administered by each nursing school, and nearly every major policy is set locally, not by Elsevier. Before you build your study schedule, confirm these details with your specific program:
| Policy | Common Range | Why It Varies |
|---|---|---|
| Required subtests | 4–9 sections | Programs pick which subtests matter; some require only Math/Reading/Vocab/Grammar, others add A&P, Biology, Chemistry, Physics, or Critical Thinking |
| Minimum score | 70%–90% per section or composite | Community colleges often set 75%; competitive BSNs set 80–85%; accelerated programs may require 90%+ |
| Retake attempts | 1–3 per year | Chamberlain allows 1 retake; Lone Star and TCC allow retakes every 60 days; some schools allow up to 6 attempts per year in 3 eligibility periods |
| Waiting period | 2 weeks – 3 months | UTRGV requires 3 weeks; Gateway and CNM require 30–45 days; ECU requires 3 months |
| Score validity | 1–2 years | Scores expire; most schools require testing within 12–24 months of application |
| Score usage | Highest, most recent, or averaged | Some schools use your highest attempt; others use most recent; a few average all attempts |
| Testing location | On-campus or remote proctoring | Some schools require on-site testing; others (e.g., Chamberlain) use remote proctoring via ProctorU |
| Cost | $35–$100 | Gateway charges $54; fees vary by school and number of sections |
Action step: Email or call your nursing program's admissions office to confirm required subtests, minimum scores, retake policy, and testing format before you start studying. Studying the wrong sections wastes weeks.
