How Hard Is the Nursing Entrance Exam? Complete Difficulty Guide 2026 July
How hard is the nursing entrance exam? 🎯 Learn what topics are tested, pass rates, and proven strategies to prepare effectively for the NEX.

If you are asking how hard is the nursing entrance exam, you are not alone. Every year, thousands of aspiring nurses across the United States sit down to face a standardized test that will determine whether they gain admission to a competitive nursing program. The nursing entrance exam is designed to measure academic readiness across multiple domains — from science and mathematics to reading comprehension and critical thinking — and nursing schools use these scores to screen applicants fairly and rigorously.
The difficulty of the nursing entrance examination varies depending on which version your target school uses. The most widely administered versions include the NLN NEX, the Kaplan Nursing Entrance Exam, the TEAS, and the HESI A2. Each test covers similar academic content but differs in format, timing, and weighting. Understanding which exam your program requires — and what that exam specifically measures — is the most important first step in your preparation journey.
Most students who have never taken a standardized science or math exam since high school find the nursing entrance exam moderately to highly challenging. The science sections in particular demand knowledge of anatomy, physiology, biology, and chemistry that many applicants have not revisited in years. However, the exam is absolutely passable with focused, structured preparation over several weeks or months. Students who begin studying early and use targeted practice materials consistently outperform those who cram in the final days before the test.
One important distinction to understand is that nursing entrance exams are not designed to trick you — they are designed to assess baseline academic competency. The questions measure whether you can apply core science and math concepts in healthcare-relevant contexts, read dense passages carefully, and think critically about clinical scenarios. The exam rewards genuine understanding over rote memorization, which means that deep comprehension of foundational concepts will serve you far better than memorizing lists of facts.
Another layer of difficulty comes from time pressure. Most nursing entrance exams are timed, and many students find themselves racing through the later sections because they spent too long on early questions. Developing pacing strategies during your practice sessions is just as important as mastering the content itself. Knowing when to skip a question and return to it later, and how to eliminate obviously wrong answer choices quickly, can add several points to your final score without any additional content knowledge.
The good news is that free, high-quality preparation resources are widely available, and structured practice tests closely mirror the real exam experience. The more familiar you become with the format, the question style, and the time constraints, the less anxiety you will feel on test day. This guide will walk you through the structure of the exam, the difficulty level of each section, proven preparation strategies, and everything else you need to know to approach your nursing entrance exam with confidence.
Nursing Entrance Exam by the Numbers

Exam Format
| Section | Questions | Time | Weight | Notes |
|---|---|---|---|---|
| Verbal Ability | 40 | 40 min | 24% | Vocabulary, reading comprehension, word associations |
| Science | 60 | 75 min | 35% | Biology, chemistry, anatomy, physiology, health |
| Mathematics | 40 | 40 min | 24% | Arithmetic, algebra, geometry, fractions, dosage calc |
| Critical Thinking | 30 | 25 min | 17% | Inference, argument analysis, logical reasoning |
| Total | 170 | 3 hours | 100% |
The science section is widely considered the most difficult part of the nursing entrance exam, and for good reason. With 60 questions covering biology, chemistry, anatomy, physiology, and general health concepts, it demands a broad base of knowledge that many applicants have not actively used since high school or a community college prerequisite course. Questions range from basic cellular biology to how organ systems interact during physiological stress — concepts that require not just memorization but genuine contextual understanding.
Biology questions on the nursing school entrance exam typically test cell structure and function, genetics, microbiology basics, and human body systems. Chemistry questions often focus on atomic structure, chemical bonding, acids and bases, and basic biochemistry relevant to pharmacology. If you earned a grade of B or better in these subjects within the past five years, you likely have a solid foundation to build on. If it has been longer, plan to spend extra study time reviewing these subjects from the ground up before moving to practice questions.
The mathematics section is challenging in a different way. The content itself — fractions, decimals, percentages, ratios, basic algebra, and dosage calculations — is not advanced mathematics. However, the time pressure and the healthcare-specific contexts in which questions are framed can trip up students who are not prepared. A question asking you to calculate the correct medication dosage given a patient's weight and a concentration in milligrams per kilogram requires both math fluency and the ability to read a word problem carefully under time constraints.
Verbal ability is frequently underestimated by nursing applicants who consider themselves strong readers. In reality, the vocabulary component of the nursing entrance exam tests medical and scientific terminology that may be entirely unfamiliar to someone who has never worked in a clinical setting. Words like "diaphoresis," "edema," and "tachycardia" appear regularly, and understanding them in context is essential. A targeted vocabulary study strategy, using flashcards focused on medical terminology, can make a significant difference in your verbal score.
Critical thinking is often the section where analytically strong students excel and where students who focus only on content memorization struggle. The questions present arguments, scenarios, or passages and ask you to evaluate the strength of evidence, identify logical fallacies, or draw inferences. The good news is that critical thinking skills can be developed through deliberate practice with sample questions — and these skills also directly translate to clinical nursing practice, so the effort is doubly worthwhile.
For those preparing for the kaplan admission test nursing entrance, the structure is slightly different. The Kaplan Nursing Entrance Exam emphasizes reading comprehension, writing, mathematics, and science, with a particular focus on practical nursing knowledge and how academic concepts apply in patient care settings. Kaplan scores are reported on a different scale, and different programs set different minimum cutoffs, so always confirm your target school's specific requirements before you begin studying.
Students who approach each section with section-specific strategies — rather than treating the exam as one undifferentiated block — consistently achieve higher scores. For science, build concept maps connecting related ideas. For math, drill calculation speed with timed sets. For verbal, study medical vocabulary in context rather than in isolation. For critical thinking, practice identifying the conclusion, premises, and assumptions in each argument before choosing your answer. Tailoring your preparation to each section's unique demands will maximize your return on every hour you invest in studying.
Kaplan Nursing Entrance Exam vs. NLN NEX vs. TEAS: What Is the Difference?
The Kaplan nursing entrance exam is used by hundreds of nursing programs nationwide and measures reading, writing, math, and science skills. The reading section presents clinical passages and asks comprehension and inference questions, while the science section covers biology and chemistry at the introductory college level. Scores are reported on a percentile scale, and most programs require a minimum composite percentile between the 50th and 75th percentile for competitive admission.
Preparation for the Kaplan nursing entrance test is well-supported by official Kaplan study guides, Kaplan nursing entrance exam practice test sets, and online adaptive question banks. Students who complete at least three full-length Kaplan nursing entrance exam practice sessions before test day report feeling significantly more comfortable with timing and question phrasing. Many find the Kaplan exam slightly more reading-intensive than the NLN NEX but less science-heavy than the HESI A2.

The 80/20 Rule of Nursing Entrance Exam Prep
Research consistently shows that 80 percent of nursing entrance exam points come from roughly 20 percent of the content — specifically, foundational biology (cell biology and body systems), basic algebra, fractions and percentages, and reading comprehension strategies. Students who master these core areas first and then expand outward consistently outperform students who try to study all content equally. Identify your highest-leverage topics early and invest the majority of your preparation time there.
Understanding pass rates and score targets is critical for setting realistic preparation goals. Nationally, the first-time pass rate for the NLN NEX hovers around 54 percent — meaning nearly half of test takers do not achieve a passing score on their first attempt. This statistic underscores how important structured preparation is and why treating the nursing entrance exam as a casual hurdle rather than a serious academic challenge is a common and costly mistake.
Score requirements vary significantly across nursing programs. Community college nursing programs typically require composite scores at the 50th percentile or above, which is a more accessible target for applicants with average academic backgrounds. University-based BSN programs, especially at selective institutions, frequently require scores at the 70th percentile or higher, with some highly competitive programs looking for scores in the 80th to 90th percentile range. Always research your specific target program's published minimum score requirements before you begin studying, and aim for a score 10 to 15 percentile points above the minimum to ensure a buffer.
One important concept to understand is that nursing entrance exam scores are reported as percentile ranks rather than raw percentages for most versions. A score at the 65th percentile means you performed better than 65 percent of all test takers in the national norm group — it does not mean you answered 65 percent of questions correctly. This distinction matters because it means that consistent, deliberate preparation that pushes your academic skills above average will translate directly into competitive percentile scores even if you do not answer every question correctly.
For students who take a nursing school entrance exam practice test and find their diagnostic score well below the target threshold, do not panic. A low diagnostic score is normal — it is the starting point, not the destination. The most important thing a low diagnostic tells you is where your study time needs to go. Students who score at the 30th percentile on their diagnostic and study consistently for 12 weeks routinely achieve scores at the 60th to 70th percentile on their actual exam. Improvement is absolutely achievable with the right approach.
Retake policies are another important consideration. Most nursing entrance exams allow retakes after a waiting period ranging from 30 days to six months, depending on the exam and the testing organization's policies. Some nursing programs limit the number of times they will accept a retake score, and others only consider your most recent score regardless of previous results. Research your target school's retake policy thoroughly before deciding whether to retake the exam after a suboptimal first attempt.
Students who fail the nursing entrance exam on their first attempt should treat it as a diagnostic rather than a defeat. Review the score report carefully — most versions provide section-level breakdowns that identify exactly where points were lost. Use this data to restructure your study plan before your next attempt, focusing intensively on your lowest-performing sections while maintaining your strengths through periodic review. Many students who earn passing scores on their second or third attempt go on to be excellent nurses, so a difficult first attempt is not predictive of your clinical potential.
Setting a specific score target in advance — rather than just hoping to pass — dramatically improves preparation quality. When you know you need a 70th percentile composite score to be competitive at your top-choice program, you can calibrate your preparation intensity accordingly. Take practice exams every two weeks, track your percentile performance across each sitting, and adjust your study schedule based on the data rather than your subjective sense of readiness. Data-driven preparation is the single most effective strategy for achieving your target score.
Many nursing programs require your entrance exam score to be submitted along with your application by a specific deadline, and some only accept scores from within the past two to three years. Check your target school's admissions page early to confirm both the score submission deadline and any expiration policy on test scores. Missing the deadline or submitting an expired score can disqualify an otherwise strong application entirely, so build exam scheduling around the application calendar, not the other way around.
One of the most common mistakes applicants make is underestimating the verbal and critical thinking sections because they believe their English skills are strong. Native English speakers often assume that vocabulary and reading comprehension questions will be easy, but nursing entrance exams specifically test medical and scientific vocabulary that is not part of everyday usage. Words like "homeostasis," "diuresis," "hypertension," and "erythrocyte" appear regularly in verbal sections, and students without clinical exposure or deliberate vocabulary study often lose significant points in this section unnecessarily.
Another frequent error is neglecting mathematics review because the topics seem basic. Fractions, ratios, and percentages are indeed foundational math skills, but many applicants have not performed these calculations by hand — without a calculator — for years. Nursing entrance exams typically prohibit calculator use on math sections, meaning that computational fluency must be developed through sustained practice with pencil-and-paper problems. Students who rediscover arithmetic fluency through daily timed practice sets reliably improve their math section scores by 10 to 20 percentage points over their diagnostic baseline.
Inadequate practice testing is perhaps the single most damaging preparation mistake. Many students spend all of their study time reviewing content notes and very little time actually sitting down and doing timed practice exams under realistic conditions. Content knowledge without test-taking experience leaves students vulnerable to time pressure, unfamiliar question formats, and test-day anxiety. The research on exam preparation is clear: distributed practice with feedback — meaning regular practice testing followed by review of incorrect answers — is far more effective than passive content review alone.
Students also frequently mismanage their time on the actual exam day. They spend too long on difficult questions early in the section, running out of time on questions they could have answered correctly later. A disciplined time management strategy — spending no more than 60 to 90 seconds per question on your first pass and marking challenging questions to revisit — prevents this common score-draining pattern. Practicing this strategy on every timed practice exam is the only way to make it automatic on test day when nerves are elevated.
For applicants considering which nursing entrance test to prepare for, it is worth researching not just your top-choice program but also your backup programs, as different schools may require different exams. Some students end up preparing for both the Kaplan and the NLN NEX, or both the TEAS and the HESI A2, because their application list spans programs that use different versions. While the core academic content overlaps significantly across all nursing entrance exams, the specific format, timing, and question phrasing differ enough that dedicated preparation for each specific exam version is worthwhile.
Sleep and physical preparation in the days leading up to the exam are also scientifically validated performance factors that students consistently underestimate. Attempting to cram new content in the 24 hours before the exam rarely improves scores and frequently increases anxiety. The night before the exam should be spent on light review of your strongest areas — reinforcing confidence rather than introducing new material — followed by early sleep. Arriving at the testing center well-rested, having eaten a nutritious breakfast, and having arrived with time to settle in comfortably significantly reduces test-day anxiety and its negative effect on cognitive performance.
Finally, remember that the nursing entrance exam is one component of your application, not the entirety of it. Strong essays, meaningful clinical or healthcare experience, letters of recommendation, and a strong GPA all contribute to your overall application package. A slightly below-target exam score can sometimes be offset by exceptional performance in other areas, and a perfect exam score does not guarantee admission if other components of the application are weak. Approach your preparation with the goal of achieving your best possible score while investing in a well-rounded application that represents the full picture of your readiness for nursing school.
Building a realistic and sustainable study schedule is the foundation of effective nursing entrance exam preparation. The ideal preparation window is 10 to 12 weeks for most applicants, though students with significant gaps in their science or mathematics background may benefit from extending this to 16 weeks. Trying to compress serious preparation into two or three weeks almost always produces anxiety, shallow content coverage, and underperformance — especially on the science section, where conceptual understanding cannot be force-fed in a short period.
Structure your study sessions in focused 45 to 60 minute blocks with short breaks between them rather than marathon three or four hour sessions. Cognitive science research consistently shows that shorter, focused study sessions with spaced repetition produce better long-term retention than extended sessions with diminishing focus. Use the last 10 minutes of each study block to review what you just covered, and revisit that material again 24 hours later and one week later to cement it in long-term memory before your exam.
Subject rotation is another powerful strategy. Rather than spending an entire week on biology before moving to mathematics, rotate through subjects across the week so that each subject is visited multiple times per week. This rotation keeps all content areas active in memory simultaneously and prevents the common experience of having well-studied content fade while you focus on a new area. A sample weekly structure might be: Monday and Thursday for science, Tuesday and Friday for mathematics, Wednesday for verbal and vocabulary, and the weekend for critical thinking and a timed practice section.
Practice questions should be integrated from the very beginning of your preparation — not saved as a final-week review exercise. Start with untimed practice to build confidence and then gradually introduce time constraints as your content knowledge improves. The goal of timed practice is not just to simulate the exam but to develop the automaticity of recall that allows you to answer familiar question types quickly and reserve your mental energy for genuinely challenging questions. Automaticity only develops through repetition over time — it cannot be rushed.
Group study can be valuable if the group stays disciplined, but it is not essential and is not right for every learner. Solo study with a detailed, written schedule is sufficient for most applicants and eliminates the scheduling complications and potential social distractions of group sessions. If you do choose to study with peers, structure sessions around specific content topics, quiz each other with practice questions, and hold each other accountable to the agreed-upon agenda rather than allowing sessions to drift into conversation.
Official study materials from the organization that administers your specific exam are always the most reliable source of practice questions. NLN provides official NEX review resources, ATI provides official TEAS study materials, and Kaplan offers official preparation for its nursing entrance test. Supplement official materials with well-reviewed third-party prep books, and be cautious of low-quality practice question banks on generic test-prep websites that may not accurately reflect the current exam format or difficulty level.
In the final week before your exam, shift from learning new material to consolidating what you already know. Spend time reviewing your most-missed practice question types, revisiting your medical vocabulary flashcards, and doing short timed drills on your calculation skills.
Take one final full-length practice exam under strict test-day conditions about five days before your actual exam — this final simulation identifies any remaining weak spots while leaving you enough time to do targeted review without exhausting yourself before the real thing. Go into test day trusting the preparation you have done and focusing on executing your strategy rather than worrying about results.
