Aspiring nurses face a gauntlet of high-stakes examinations: the HESI A2 or ATI TEAS for nursing school admission, rigorous coursework exams throughout the program, and finally the NCLEX-RN for licensure. Each exam tests different competencies, rewards different preparation strategies, and carries its own unique pressure. Understanding how each exam works — and how to prepare specifically for it — is the difference between struggling through and moving forward with confidence.
This guide synthesizes advice from experienced nursing educators, insights from the cognitive science of learning, and practical strategies from students who have successfully navigated all three exams. Whether you are preparing for your first nursing entrance exam or your NCLEX after graduation, this guide has something specific and actionable for you.
Part 1: Preparing for Nursing School Entrance Exams (HESI A2 and ATI TEAS)
Both the HESI A2 and ATI TEAS serve as gatekeepers to competitive nursing programs. Most BSN and ADN programs accept either exam (check with your specific target program), though some prefer one over the other. Both test broadly similar content: reading comprehension, math, science (anatomy and physiology, biology, chemistry), English language, and vocabulary. The key differences lie in question format, section weighting, and scoring structure.
Why Entrance Exam Preparation Matters More Than You Think
Nursing program admissions are intensely competitive. At many community college ADN programs, the difference between an accepted application and a waitlisted one is less than five TEAS composite score points. A student who prepares seriously for six to eight weeks and scores in the 85th percentile will almost always advance ahead of a student who "takes it cold" and scores in the 65th percentile — even if their GPA is identical. Your entrance exam score is one of the few elements of your application you can directly control with preparation.
The Science Section: The Critical Differentiator
Both the HESI A2 and TEAS include a science section that tests biology, anatomy and physiology, and chemistry (more heavily on HESI) or life science, Earth science, and physical science (on TEAS). This section is where most students' scores diverge. Students who scored above 90% on science sections were almost exclusively those who devoted at least 50% of their preparation time to science — despite it being only about 25-30% of the total test content.
High-Priority Science Topics (Both Exams)
- Cell structure and function (organelles, cell membrane, mitosis)
- Basic genetics (DNA, RNA, protein synthesis, Mendelian inheritance)
- Body systems — cardiovascular, respiratory, nervous, musculoskeletal
- Homeostasis and feedback mechanisms
- Basic chemistry — atoms, molecules, pH, acids/bases, chemical bonds
- Nutrition and metabolism fundamentals
Math: Dosage Calculation Is the Real Goal
The math sections on both entrance exams test arithmetic, algebra, and basic statistics. However, the real reason nursing programs care about math performance is dosage calculation — the critical skill of computing correct medication doses. As you prepare, focus especially on unit conversions, proportions, and percentages, as these are the foundation of clinical dosage calculations you will do every day as a nurse. If you master these core skills, the entrance exam math section becomes significantly more manageable.
An 8-Week Entrance Exam Study Plan
| Week | Focus | Daily Time |
|---|---|---|
| 1 | Diagnostic full practice test; identify weak areas | 2 hours |
| 2 | A&P: cells, tissues, skeletal, muscular systems | 2 hours |
| 3 | A&P: cardiovascular, respiratory, nervous systems | 2 hours |
| 4 | Chemistry: atoms, bonding, pH, biochemistry basics | 2 hours |
| 5 | Math: fractions, decimals, ratios, unit conversions | 1.5 hours |
| 6 | Reading comprehension + vocabulary + English grammar | 1.5 hours |
| 7 | Second full practice test; targeted review of missed areas | 2.5 hours |
| 8 | Final review; light study; rest before exam | 1 hour |
Part 2: Surviving Nursing School Coursework Exams
Once inside a nursing program, students face a constant barrage of exams — pharmacology, fundamentals, medical-surgical, OB, pediatrics, psychiatric nursing, and more. These exams are not like undergraduate academic tests. They are almost entirely scenario-based and test clinical judgment rather than factual recall. A student who relies on memorization as their primary study strategy will struggle severely in nursing school.
The NCLEX-Style Thinking You Must Develop
Most nursing school exams use NCLEX-style questions: alternate format questions, prioritization questions, and scenario-based multiple choice. The correct answer is rarely the one that "sounds most comprehensive" — it is the one that reflects proper nursing priorities in the specific clinical situation described. Learn to recognize Maslow's Hierarchy of Needs in clinical prioritization (airway before breathing before circulation before everything else), the ABC framework (Airway, Breathing, Circulation), and the principle of "assess before act."
When you see a question asking "which patient should the nurse see first," you are being tested on prioritization. The patient with an airway problem always comes first, regardless of how dramatic the other patients' conditions sound. Practicing thousands of NCLEX-style questions throughout your nursing program builds the clinical reasoning reflexes you need both for school exams and the NCLEX itself.
Pharmacology: A Special Challenge
Pharmacology is the subject that fails the most nursing students — not because it is conceptually impossible, but because students treat it as a memorization problem when it is actually a pattern-recognition problem. Organize drugs by class first, then memorize specific drugs within each class. If you understand that beta-blockers slow the heart rate and reduce blood pressure by blocking beta-adrenergic receptors, you can extrapolate effects, adverse reactions, and nursing implications for any drug in that class — not just the one you memorized. Create drug class cards rather than individual drug cards.
Part 3: The NCLEX-RN — Licensure Exam Mastery
The NextGen NCLEX (launched in 2023) introduced significant changes to the traditional exam format. The test now includes clinical judgment measurement model (CJMM) questions — including case studies, extended multiple response, matrix grids, and bow-tie items — alongside traditional multiple choice. The exam adapts to your performance and can run anywhere from 75 to 150 questions, stopping when it has reached statistical confidence about your competency level.
The CJMM Framework: Your NCLEX Compass
Every NCLEX question — regardless of format — is testing one of six cognitive skills in the Clinical Judgment Measurement Model: Recognize Cues, Analyze Cues, Prioritize Hypotheses, Generate Solutions, Take Action, and Evaluate Outcomes. Understanding which cognitive skill a question is testing helps you approach it correctly. A "Recognize Cues" question asks what data is relevant to the patient's condition. A "Prioritize Hypotheses" question asks which patient problems are most urgent. A "Take Action" question asks what intervention the nurse should implement first.

Using Question Banks Strategically
The most effective NCLEX preparation tools are question banks — UWorld, NCSBN Learning Extension, and Kaplan are the industry leaders. Do not just answer questions and check the answer key. Read every single rationale, including for questions you answered correctly. The rationale teaches the clinical reasoning behind the answer, which transfers directly to similar questions you will encounter on the actual exam.
Mental and Physical Preparation for Test Day
For all three exams, the week before the test should involve decreasing intensity of study (not increasing), ensuring you are sleeping seven to nine hours per night, and avoiding learning large amounts of new material. The night before the exam, review your notes lightly for 30–45 minutes, then stop studying. Eat a protein-rich breakfast on exam day. Arrive at the testing center 20 minutes early. During the exam, use the process of elimination systematically for any question you are unsure about — never leave a question blank if you can reason your way to a likely answer.
Conclusion
Nursing examinations test not just knowledge but the clinical reasoning that separates competent nurses from unsafe ones. The most successful nursing students approach each exam as practice in clinical thinking — not as a memory retrieval exercise. Combine deliberate content review with consistent practice question completion, develop your clinical judgment through the CJMM framework, and give your brain the sleep and rest it needs to consolidate learning. You are preparing not just to pass a test, but to become the kind of nurse that patients can trust.
