RN school is one of the more demanding paths in higher education, with roughly 20% of nursing students in the United States dropping out before finishing. The difficulty comes from multiple directions at once: dense science coursework, a testing style unlike anything you’ve encountered before, clinical rotations that put you in real patient-care situations, and a weekly time commitment that leaves little room for anything else. It’s not impossible, but it requires a level of sustained effort that catches many students off guard.
Getting In Is the First Challenge
Nursing programs are competitive, and the difficulty starts before classes even begin. Many schools receive far more applicants than they can accept. At the University of San Francisco’s BSN program, for example, the average GPA of admitted students has climbed from 3.96 in 2022 to 4.09 in 2025. That’s a weighted GPA, meaning admitted students were earning A’s in honors or AP courses in high school.
Community college ADN programs can be just as selective in their own way. While they may not require GPAs that high, many use waitlists or point-based ranking systems that factor in prerequisite grades, entrance exam scores, and sometimes healthcare experience. Most programs require you to pass an entrance exam like the TEAS or HESI A2, and individual schools set their own minimum score thresholds. There’s no universal passing standard, so you’ll need to research requirements at each school you’re applying to.
The Coursework Is Genuinely Heavy
Nursing school packs an enormous amount of information into a short timeframe. Whether you’re in a two-year ADN program or a four-year BSN program, the core nursing courses are intense. The subjects that trip up the most students are Anatomy and Physiology, Pharmacology, Microbiology, and Medical-Surgical Nursing.
Pharmacology is widely considered the single hardest class in many nursing programs. You’re learning hundreds of medications, their mechanisms, side effects, interactions, and the clinical reasoning behind when to give (or withhold) each one. It’s not just memorization. You need to understand why a drug works, recognize when a patient’s symptoms call for it, and catch dangerous combinations.
Medical-Surgical Nursing is another turning point. It’s often one of the first courses where you’re expected to pull together everything you’ve learned about disease processes, medications, and patient assessment into a single, integrated picture. Students who could handle individual subjects sometimes struggle when they’re asked to think across all of them simultaneously.
BSN programs layer additional coursework on top of what ADN programs cover. According to the American Nurses Association, BSN students also take courses in nursing theory, public health, research methods, and ethics. The clinical core is similar between the two paths, but the BSN adds breadth that extends the total time commitment to four years.
Expect to Study 20 to 30 Hours a Week
A common guideline in nursing education is two hours of study time for every one hour of class. For a full-time nursing student, that works out to around 24 hours of studying per week, on top of your actual class and clinical hours. Spread across seven days, that’s about three to four hours of studying every single day with no days off.
This is where many students underestimate nursing school. The total weekly commitment, including lectures, labs, clinicals, and independent study, can easily reach 40 to 50 hours. If you’re working a job or caring for a family, the math gets very tight very fast. Students who succeed typically build a rigid schedule early and protect their study time aggressively.
The Exams Don’t Test What You’d Expect
One of the biggest adjustments in nursing school is the testing style. If you’re used to exams that reward memorization, you’re in for a shock. Nursing exams are designed around application-level thinking, meaning they assume you already know the facts and instead test whether you can use that knowledge in realistic patient scenarios.
A typical question won’t ask you to define a condition. It will give you a patient with specific vitals, symptoms, and history, then ask you to decide what to do first, what’s most dangerous, or which intervention takes priority. Two or three of the answer choices will sound reasonable. Picking the best one requires clinical reasoning, not just recall.
Select All That Apply questions (commonly called SATA) add another layer of difficulty. Instead of choosing one correct answer from four options, you evaluate each option independently and select every one that applies. There’s no partial credit on most school exams, so missing one correct option or including one wrong option means the entire question is marked wrong. Students often describe these as the most stressful question type they encounter.
This testing style mirrors the NCLEX, the national licensing exam you take after graduation. The newest version, the Next Generation NCLEX, has added new question formats that specifically measure clinical judgment. While partial credit is now possible on some NCLEX questions, the overall difficulty hasn’t decreased. The exam adapts to your ability level in real time, getting harder as you answer correctly.
Clinicals Add Physical and Emotional Demands
Classroom difficulty is only part of the picture. Clinical rotations place you in hospitals, nursing homes, and community health settings where you’re responsible for real patients under the supervision of an instructor. You’ll work 8- to 12-hour shifts, often starting early in the morning, and you’re expected to arrive prepared with research on your assigned patients’ conditions and medications.
The emotional weight catches students off guard too. You may care for patients who are dying, who are in crisis, or who are dealing with situations you’ve never encountered before. Learning to process that while still performing clinical skills competently is a genuine challenge that no amount of textbook study prepares you for.
ADN vs. BSN: Different Length, Similar Intensity
An ADN program compresses the core nursing education into about two years (plus prerequisites that often take an additional year or more). A BSN program spans four years and includes broader coursework in leadership, research, and community health. Both qualify you to sit for the NCLEX and become a licensed RN.
The clinical nursing courses in both programs are comparably difficult. Where they differ is pacing. ADN programs cram the same dense material into fewer semesters, which can make individual semesters feel more overwhelming. BSN programs spread the load over more time but add additional academic demands. Neither path is easy, and the choice often comes down to your timeline, budget, and career goals rather than which one is “harder.”
Why Students Drop Out
That 20% attrition rate in U.S. programs reflects a mix of academic and personal factors. Some students fail critical courses that must be passed with a C or higher (and some programs require a B). Others leave because of financial strain, burnout, or life circumstances that make the time commitment unsustainable.
Programs with the highest attrition rates tend to serve students who are balancing school with significant work or family responsibilities. The difficulty of the material itself is only one piece. The sustained intensity over two to four years, with little downtime between semesters, is what wears many students down. Students who make it through consistently cite strong study habits, peer support, and realistic expectations about the workload as the factors that kept them on track.
Nursing school is hard in a specific way: it’s not that any single concept is beyond reach, but the volume of information, the unfamiliar testing style, the clinical demands, and the relentless pace combine into something that requires more from you than most academic programs. Students who go in expecting that tend to do far better than those who assume it will feel like a typical college experience.
