Choosing the right HESI comprehensive review book is one of the most important decisions you will make on your path to nursing school admission. The HESI A2 exam serves as a critical gatekeeping assessment for hundreds of nursing programs across the United States, and the quality of your study materials can mean the difference between a passing score and having to retake the test. Whether you are aiming for an associate degree in nursing or a bachelor of science in nursing program, a solid review book provides the structured, subject-by-subject coverage you need to feel confident on exam day.

The HESI exam tests knowledge across up to nine different subject areas, including Anatomy and Physiology, Biology, Chemistry, Grammar, Mathematics, Reading Comprehension, Vocabulary, Physics, and a Learning Style assessment. Not every nursing program requires all sections, so it is essential to research exactly which subtests your target schools require before you begin studying. A high-quality HESI A2 review book will map out these subject areas clearly and help you allocate your study time according to your individual needs and program requirements. If you want additional hesi practice questions alongside your book, free online resources can complement your reading effectively.

Many students feel overwhelmed when they first open a comprehensive review book and see the sheer volume of content they need to master. The key is not to read every page from cover to cover in a passive way, but rather to use the book strategically. Start by taking a diagnostic practice test to identify your weakest subject areas, then focus your reading time where it will have the greatest impact on your overall composite score. Most review books include both a pre-test and a post-test specifically for this purpose, making them far more effective than reading individual textbooks.

The HESI practice test sections embedded throughout the best review books are arguably their most valuable feature. Research consistently shows that active recall through practice questions is far more effective for long-term retention than passive reading. When you encounter a practice question and get it wrong, the explanation provided by the review book teaches you not just the correct answer but the underlying reasoning, which helps you handle variations of the same question on the actual exam. Look for books that include at least 500 practice questions with detailed rationales.

Online platforms have expanded the definition of what a review book can be. Today, the best HESI study materials come in both print and digital formats, and many publishers bundle their physical books with online question banks and video lectures. These hybrid packages give you the depth of a traditional textbook alongside the flexibility of mobile-friendly practice tests you can use on your lunch break or during your commute. When evaluating your options, check whether the digital companion includes full-length hesi test practice exam simulations that mirror the real test interface.

Budget is a real consideration for nursing students, many of whom are balancing school costs, living expenses, and work schedules. Review book prices range from about $30 for basic editions to $60 or more for premium bundles that include online access codes. Before purchasing, check whether your school library has copies available for short-term checkout, and look for used editions from previous years — the core nursing science content changes very little from one edition to the next, though it is always wise to verify that the subject weightings in an older edition still match your program's current requirements.

This guide will walk you through everything you need to know to choose and use the best HESI comprehensive review book, build an effective study schedule, and walk into your exam with the confidence and preparation that translates into a strong score. From subject breakdowns and top book recommendations to practice strategies and test-day tips, you will find actionable, research-backed advice at every step of your preparation journey.

When it comes to selecting the best HESI comprehensive review book, the market offers several strong contenders, each with distinct strengths. The Elsevier HESI A2 Study Guide is widely considered the gold standard because it is produced by the same company that develops the actual HESI exam. This means the content coverage, question style, and difficulty level are precisely calibrated to match what you will encounter on test day. The Elsevier guide covers all nine subject areas and includes two full-length practice exams with detailed answer explanations.

Mometrix's HESI A2 Secrets Study Guide is another popular option that earns high marks for its readability and strategic test-taking tips. Unlike some densely written textbooks, the Mometrix guide is written in plain language that is easy to understand even for students who have been out of school for several years. It places particular emphasis on test-taking strategy alongside content review, teaching you how to approach unfamiliar questions by using process of elimination, keyword analysis, and educated guessing when necessary. For students who struggle with test anxiety, this strategic focus can be enormously valuable.

Kaplan's HESI A2 Prep Plus is a strong choice for students who want a heavily practice-oriented approach. The Kaplan guide includes over 1,000 practice questions across all subjects, making it one of the most question-rich resources available in a single volume.

Each section opens with a concise content review followed by extensive practice sets, and the book's online companion provides two additional full-length computerized practice exams. If you learn best by doing rather than reading, the Kaplan format aligns particularly well with that learning style. You can further supplement with dedicated hesi exam practice resources to cover specialized nursing pathophysiology content.

McGraw-Hill's HESI A2 Practice Tests is a slightly different kind of resource — it focuses almost entirely on practice rather than content review, offering eight full-length practice exams in a single volume. This format works best when used alongside a content-heavy review book rather than as a standalone resource. Students who feel reasonably confident in the subject matter but want to build speed, endurance, and familiarity with the question format will find the McGraw-Hill approach particularly effective. Using it in the final two to three weeks of preparation, after you have completed your content review, is the most efficient strategy.

The HESI A2 exam has evolved over the years, and review books updated in 2024 or 2025 reflect the most current test blueprint and content weightings. One of the most important things to verify before purchasing any review book is its publication date. An older edition from 2020 or earlier may omit recently added content areas or use a question format that no longer matches the current computerized adaptive testing interface. When in doubt, check the publisher's website for the most recent edition and read recent student reviews on platforms like Reddit's r/prenursing community.

Digital-first learners may prefer to complement their review book with an online question bank subscription service. Platforms like Nurse.plus, PrepU, and the official Elsevier online companion offer thousands of additional practice questions with adaptive difficulty settings that automatically focus your practice on your weakest areas. These platforms track your performance over time, providing analytics that show exactly which subtopics need the most attention. Many students find that the combination of a comprehensive print book and an online question bank produces better outcomes than either resource alone.

Price comparison is worth spending five minutes on before you commit to a purchase. Amazon, Chegg, and Barnes and Noble all stock the major HESI review books, and prices can vary by $10 to $20 for the same edition. Many students also find success purchasing the Kindle or digital PDF version, which is often $5 to $15 cheaper than the print edition and has the added benefit of being instantly searchable.

If you are studying with a classmate or study group, consider splitting the cost of a premium bundle that includes online access and dividing practice sections between you before comparing notes on challenging questions.

Understanding what no HESI policies mean for your nursing school applications is an increasingly important consideration in 2025 and 2026. A growing number of nursing programs have moved away from requiring the HESI A2 as a mandatory admissions assessment, adopting instead a holistic review process that considers GPA, prerequisite grades, personal statements, and letters of recommendation. This shift was accelerated by the COVID-19 pandemic, when testing center closures made standardized admissions testing impractical, and many schools discovered that their admissions outcomes were not significantly different without the test requirement.

However, do not assume that a "no HESI" policy at one school means the same policy at your other target programs. Admissions requirements vary enormously between institutions, and some schools that dropped the HESI requirement temporarily during the pandemic have since reinstated it. Always verify current requirements directly through the nursing school's official admissions page or by calling the department. Application deadlines and testing schedules mean that discovering you need a HESI score at the last minute can seriously jeopardize your admission timeline.

For programs that do require the HESI A2, minimum score requirements typically fall between 70% and 80% composite, though competitive programs at major university nursing schools may expect composites of 85% or higher to be a competitive applicant. Some programs set different minimum scores for different subtests — for example, requiring at least 75% on the science subtests while accepting 70% on the grammar subtest. Understanding the specific scoring thresholds at each of your target programs allows you to focus your preparation energy strategically rather than trying to achieve maximum scores across every single subtest.

The HESI A2 exam is administered through Elsevier's testing system, and most schools use a proctored on-campus testing format or an approved testing center. A smaller but growing number of programs accept remotely proctored HESI results, though the remote format has stricter technical requirements and may not be available at all institutions. When registering for your exam, confirm with your nursing program whether they accept remotely proctored scores or require you to test at a physical location. This information is usually available on the program's admissions FAQ page but can occasionally require a direct phone call to confirm.

Score reporting for the HESI A2 is handled electronically through Elsevier's platform. Your scores are typically available within 24 to 48 hours of completing your exam, and you can request that they be sent directly to your nursing program. Keep a personal copy of your score report, as some programs require you to self-report your scores on the application and then verify them with the official Elsevier transcript later in the process.

Score reports show your performance on each subtest individually as well as your overall composite score, giving you detailed feedback on exactly where you excelled and where additional preparation might be needed if you choose to retake.

The question of when to schedule your HESI A2 exam relative to your application deadline deserves careful thought. Most advisors recommend scheduling your exam at least six to eight weeks before your application deadline. This timeline gives you enough buffer to retake the exam if your first attempt does not produce the score you need.

Most testing centers enforce a 60-day waiting period between attempts, so if you take the exam too close to your deadline and need to improve your score, you may find yourself missing the application window entirely. Build your study timeline backwards from your target exam date rather than from your application deadline.

Students who are applying to highly competitive programs sometimes wonder whether retaking the HESI A2 to improve an already-passing score is worth the investment of time and the $50 to $100 retesting fee. The answer depends on the competitive landscape of your target programs. For open-enrollment community college nursing programs with a first-come, first-served acceptance policy, a passing score is all you need.

For selective BSN programs at research universities where admissions is highly competitive, improving your score from 78% to 88% can meaningfully strengthen your application. Research each program's published acceptance statistics and talk to an admissions advisor before deciding whether to retake.

Effective use of a HESI comprehensive review book requires more than simply reading through the chapters in order. The most successful students approach their review book as a flexible toolkit, moving between sections based on their diagnostic results and adjusting their depth of study based on how much each subject area is weighted in their target program's requirements. This adaptive approach consistently produces better outcomes than the passive cover-to-cover reading strategy that many students default to when they first open their book.

Active note-taking while reading your review book dramatically improves retention compared to highlighting alone. When you encounter a concept that is new or difficult, pause and write a brief summary in your own words in the margins or in a separate notebook. This process of restating information forces your brain to process the material more deeply than passive reading and creates a personalized set of study notes that you can review quickly in the days leading up to your exam. Research in cognitive science consistently supports this elaborative encoding strategy as one of the most effective learning techniques available.

Study groups can be a powerful complement to solo review book study, particularly for students who find it difficult to stay motivated during long solo study sessions. An effective nursing school study group meets two to three times per week, divides content review responsibilities between members, and spends the majority of group time quizzing each other rather than re-reading material together.

If your group includes members with different academic backgrounds — for example, some with strong science foundations and others with stronger English language skills — take advantage of this diversity by having each member teach their areas of strength to the group.

For students who need specialized support with the hesi test prep resources related to health assessment content, supplemental focused guides can fill gaps that a general comprehensive review book may leave. Health assessment, pharmacology, and pathophysiology are areas where some students benefit from dedicated resources that go deeper than a broad overview. The key is to assess whether your review book's coverage of these areas is sufficient for your program's specific subtest requirements before investing in additional resources.

Time management on exam day is a skill that must be practiced, not improvised. The HESI A2 allocates specific time limits for each subtest, and running out of time on one section can significantly drag down your composite score. During your practice sessions, track how many minutes per question you are averaging on each subtest.

For most subtests, a pace of 60 to 90 seconds per question is appropriate. If you consistently find yourself spending three or four minutes on individual science questions, that is a signal to spend more time on content mastery rather than question strategy — slow question-answering speed often indicates gaps in foundational knowledge rather than test-taking inefficiency.

The night before your HESI A2 exam, resist the temptation to cram new material from your review book. By the eve of your exam, you have learned what you have learned, and attempting to absorb new content in the final hours is more likely to increase your anxiety than improve your performance.

Instead, spend 30 to 45 minutes doing a light review of your personalized summary sheets and flashcards, then spend the rest of the evening doing something relaxing. Ensure you get seven to eight hours of sleep, eat a balanced meal before the exam, and arrive at the testing center at least 15 minutes early to give yourself time to settle in before the clock starts.

Interpreting your score report after the exam gives you valuable information regardless of whether you are satisfied with your performance. Each subtest score tells you something specific about your knowledge and test-taking abilities in that domain.

If you scored well on Reading Comprehension and Grammar but below your target on Biology and Chemistry, you now have a very clear roadmap for your retake preparation — one that is far more efficient than starting from scratch with a general review. Many students find that a targeted four-week retake preparation focused exclusively on their weakest two or three subtests produces a more significant composite score improvement than a second full eight-week general review.

Building sustainable study habits is the foundation of any successful HESI A2 preparation strategy. The students who perform best on the exam are rarely those who study the most total hours — they are the ones who study most consistently and who use their time most deliberately.

Research on learning and memory shows that distributed practice, spreading your study sessions out over several weeks rather than cramming everything into a short period, produces significantly better long-term retention of the material. Your comprehensive review book is most effective when used as part of a structured schedule that you follow consistently over six to eight weeks.

The Pomodoro Technique is particularly well-suited to HESI A2 preparation from a review book. This method involves studying in focused 25-minute blocks followed by a 5-minute break, with a longer 20 to 30-minute break after every four cycles. The short, focused intervals help maintain concentration and prevent the mental fatigue that comes from trying to read for two or three hours straight without breaks. During your breaks, avoid screens if possible — a short walk or stretching routine will refresh your focus more effectively than scrolling through social media.

Vocabulary building is one of the most underinvested areas in HESI A2 preparation, partly because it feels less structured than studying biology or practicing math problems. But the Vocabulary and General Knowledge subtest can account for a significant portion of your composite score at many programs, and it is an area where consistent daily practice produces measurable improvement.

Rather than trying to memorize long word lists in single sessions, commit to learning 10 to 15 new vocabulary words per day throughout your preparation period. Over six weeks, this adds up to 400 to 600 new words — a substantial vocabulary expansion that will serve you well both on the exam and in nursing school.

The Reading Comprehension subtest rewards a specific reading strategy that many students do not discover until they have already taken the exam once. Rather than reading the passage in full before looking at the questions, many test-taking experts recommend briefly previewing the questions first, then reading the passage with those specific questions in mind.

This targeted reading approach allows you to identify relevant information more quickly and reduces the time you spend re-reading passages to find answers. Practice this strategy during your review sessions using the reading comprehension sections in your comprehensive book to determine whether it works for your learning style.

One often-overlooked section of the HESI A2 is the Learning Style subtest, which does not have a traditional right-or-wrong scoring format. Instead, it assesses your preferred learning modalities — visual, auditory, reading/writing, or kinesthetic — and provides your nursing program with information about how you learn best. There is no way to study for this section and no reason to stress about it. Simply answer the questions honestly, as the results are primarily used to help nursing faculty tailor instructional approaches for incoming students rather than as an admissions screening tool.

For students balancing work and family responsibilities alongside their HESI A2 preparation, mobile-friendly study tools that complement your review book can maximize the productivity of small pockets of time throughout the day. Flashcard apps like Anki or Quizlet allow you to practice vocabulary, anatomy terms, and key science concepts during a commute, a lunch break, or a few minutes between tasks. Creating your digital flashcard decks directly from your review book's key terms lists means your mobile practice is perfectly aligned with your primary study resource, creating a cohesive and reinforcing preparation ecosystem.

Motivation management is a genuine challenge during multi-week standardized test preparation. Setting intermediate goals and celebrating small wins helps maintain the momentum needed to sustain consistent study habits over six to eight weeks. Consider setting weekly score targets on your practice subtests and tracking your improvement visually on a chart or calendar. Many students find that seeing their practice scores gradually climb from 70% toward 85% over the course of their preparation is highly motivating and provides concrete evidence that their effort is producing results.

Remember that the hesi exam is a learnable test — with the right materials, the right strategy, and consistent effort, virtually every student can achieve the passing score they need to advance to the next stage of their nursing education journey. Resources like new balance hesi low v2 question banks provide extensive additional practice that pairs perfectly with your comprehensive review book for final-stage preparation.
