The NEX—the National League for Nursing's Nursing Entrance Exam—is a pre-admission test used by many nursing programs to assess whether applicants have the academic foundation to succeed in nursing school. If you're applying to an LPN or ADN program that requires the NEX, passing it is one of the first real gates between you and nursing school.
Practice testing is the most effective way to prepare. The NEX tests subjects that many candidates haven't studied formally in years—anatomy, chemistry, math—and the questions are designed to assess genuine understanding, not surface recall. The more practice you do before exam day, the more familiar the question format becomes and the more confident you'll be when it counts.
The NLN NEX (Nursing Entrance Exam) is developed by the National League for Nursing and used by nursing schools as part of their admissions screening process. It's distinct from the HESI A2 and the TEAS—three different entrance exams are used by different programs, and you'll need to confirm which one your target schools require.
The NEX specifically is associated with programs that use the NLN Pre-Admission Examination (PAX) system. If your program asks for the NLN NEX or NLN PAX, you're taking the same exam family.
The exam is computer-adaptive in some administrations, meaning the difficulty of questions adjusts based on your performance. This format is more efficient for measuring your ability level but can feel disorienting if you're not expecting it—questions that seem harder might mean you're doing well, not that you're failing.
The NEX covers three main content areas:
Verbal Ability (60 questions, 45 minutes): Vocabulary in context, reading comprehension, and verbal reasoning. Questions test your understanding of medical and academic vocabulary as well as your ability to interpret passages and draw inferences. This section rewards candidates with broad reading habits and strong vocabulary.
Mathematics (40 questions, 45 minutes): Arithmetic, fractions, decimals, percentages, ratios, basic algebra, and some geometry. The math on the NEX is applied rather than theoretical—expect questions that ask you to calculate medication doses, interpret data, or work through real-world problem scenarios relevant to nursing.
Science (60 questions, 60 minutes): The broadest and often most challenging section. Covers biology (cell structure, genetics, body systems), chemistry (atomic structure, chemical reactions, pH, acids and bases), anatomy and physiology, physics (basic concepts like force, energy, pressure), and Earth science. This section often surprises candidates because the breadth of science content is wider than many expect.
Total testing time is approximately 2.5–3 hours for most administrations. Exact timing varies by testing center and administration format.
Each nursing program sets its own minimum composite or section-specific scores for the NEX. There's no universal passing score—a program in one state might accept a composite percentile of 50, while another program is highly selective and only admits candidates scoring at the 80th percentile or above.
Check the specific requirements for every program you're applying to. Some programs weight sections differently or have floor scores in specific sections—you might hit the composite minimum but fail to meet a required floor in the science section, which could still result in rejection.
Percentile scores on the NEX reflect how you performed relative to the norm group (other nursing school applicants who've taken the exam). A raw score gets converted to a percentile that nursing programs use for comparison. Because the score is relative, your preparation quality directly affects your competitive standing.
Each section of the NEX responds differently to preparation strategies.
If vocabulary is your weak point, the most effective prep is daily exposure to new words in context—read medical articles, science publications, and academic texts. Flashcard apps can help, but passive memorization of definitions alone is less effective than seeing words used in sentences. For reading comprehension, practice reading technical passages and answering questions about main idea, inference, and author purpose.
The math section rewards systematic practice. Start with a diagnostic to identify which operation types give you trouble—fractions, percentages, and algebra are the most common weak points. Then practice those specific areas daily with timed problem sets. The key for the NEX math is speed and accuracy on relatively straightforward operations; don't let small arithmetic errors cost you on questions you conceptually understand.
Learn the nursing math conversions that appear frequently: unit conversions, IV drip rate calculations, and basic dosage calculations. These appear in contextualized form on the exam, so recognizing what type of problem you're dealing with is half the battle.
This section requires the most preparation time for most candidates because the content breadth is wide. The highest-yield science topics for the NEX:
Use practice tests to identify which science subtopics give you the most trouble, then focus your review there. It's inefficient to study everything equally when your weaknesses are concentrated in specific areas.
Candidates with a strong science background and solid math skills may be ready in 3–4 weeks of focused study. Those who haven't studied biology or chemistry recently typically need 6–10 weeks to adequately cover the science content.
A realistic 6-week plan:
Weeks 1–2: Take a diagnostic practice test to assess your starting point across all three sections. Review fundamental concepts in your weakest science areas—don't try to cover everything, focus on where your practice scores are lowest.
Weeks 3–4: Intensive daily practice with section-specific questions. Math should be daily regardless of your comfort level—speed matters, and you need to maintain accuracy under time pressure. Continue science review with emphasis on anatomy and chemistry.
Weeks 5–6: Full practice exams under timed conditions. Score yourself, review every error, and identify any remaining gaps. In the final week before the exam, review high-frequency vocabulary, refresh math shortcuts, and don't cram new science content—focus on solidifying what you've already learned.
The nex nursing entrance exam is achievable for any motivated candidate who prepares systematically. The content isn't impossible—but it does require that you engage with the material actively rather than just reading through notes.
Practice tests are the clearest signal of where you stand and where you need to focus. A single diagnostic session across all three NEX sections tells you more about your readiness than any amount of reading study guides passively. Work through practice questions by section, review your errors carefully, and track your progress week by week. The NEX is a learnable exam—consistent preparation gets results.
