A Bachelor of Science in Nursing (BSN) requires approximately 120 credit hours, with prerequisites in anatomy, physiology, microbiology, chemistry, nutrition, and statistics, followed by nursing-specific courses in pharmacology, pathophysiology, health assessment, medical-surgical nursing, pediatrics, obstetrics, mental health, and community health. Clinical rotations (700-1,000+ supervised hours in hospitals and healthcare facilities) are required. After graduation, you must pass the NCLEX-RN exam to become a licensed registered nurse.
The real fear behind this search is not about the course list — it is about whether you can handle the emotional weight of nursing school and the profession. The coursework is rigorous, the clinical hours are demanding, and the responsibility of caring for real patients during clinicals is unlike anything in a classroom. But nursing programs are designed to prepare you gradually, and the vast majority of students who complete the prerequisites and gain admission successfully graduate and pass the NCLEX.
The National Center for Education Statistics reports that nursing is one of the most awarded bachelor's degrees in the United States, with high and growing enrollment1. The demand for nurses continues to grow, and the career provides job security, geographic flexibility, and multiple specialization paths that few other degrees can match.
For career paths and salary analysis, see the nursing degree overview. This page covers exactly what the program requires.
The prerequisite courses (anatomy, physiology, microbiology, chemistry) are where most nursing applicants are filtered out — not the nursing courses themselves. Programs use your prerequisite GPA as the primary admission criterion, and a B or higher in each science course is typically the minimum to be competitive. Take these courses seriously from day one, and retake them if necessary before applying to the nursing program.

- Senior Capstone/NCLEX Preparation — comprehensive review and practice for the licensing exam.
BSN vs ADN: Which Path?
BSN (Bachelor of Science in Nursing) — four-year degree at a university. Increasingly the preferred (and sometimes required) credential for hospital employment. Includes leadership, research, and community health content that ADN programs do not.
ADN (Associate Degree in Nursing) — two-year degree at a community college. Provides eligibility for the NCLEX-RN. Many hospitals now require or prefer BSN-prepared nurses, and many ADN graduates pursue RN-to-BSN bridge programs while working.
The trend in healthcare is strongly toward BSN as the minimum credential. Many major hospital systems require a BSN for new hires or require ADN nurses to complete a BSN within a specified time frame after hiring.
Common Specializations (Post-Licensure)
Nursing specialization happens primarily through work experience and graduate education, not undergraduate concentrations. However, some BSN programs offer tracks or electives in:
Critical care — ICU nursing preparation. Advanced assessment and technology. Pediatrics — focused clinical rotations in children's hospitals. Community/public health — emphasis on population health and health education. Mental health — additional psychiatric nursing coursework and clinicals. Research — preparation for graduate research programs (BSN-to-PhD pathways).
Nursing program admission is highly competitive at most schools. GPA in prerequisite science courses is the primary criterion, and many programs have a minimum prerequisite GPA of 3.0-3.5. Some programs also require the TEAS (Test of Essential Academic Skills) exam. Apply to multiple programs and have backup plans, including ADN programs that can serve as a pathway to BSN completion later.
Prerequisites and Admission Requirements
Nursing programs have a separate, competitive admission process from the university. Requirements typically include:
- Minimum prerequisite GPA (3.0-3.5 for competitive programs)
- TEAS or HESI entrance exam scores
- Completed prerequisites with minimum grades (often B or better in sciences)
- Background check and drug screening
- CPR/BLS certification
- Immunization records and health clearances
- Letters of recommendation
- Personal statement
Timeline: Most students complete prerequisites during their first two years and apply to the nursing program for admission to the clinical (junior/senior) years. Direct-admit programs accept students as freshmen but may still require maintaining minimum grades in prerequisites.
Skills You'll Build (and What Employers Actually Value)
Clinical reasoning — assessing patients, identifying problems, and making care decisions. The core intellectual skill of nursing. Technical skills — IV insertion, medication administration, wound care, assessment techniques, and equipment operation. Communication — patient education, interdisciplinary team communication, and documentation. Time management under pressure — managing multiple patients with competing needs simultaneously. Emotional resilience — coping with suffering, death, and high-stress situations while maintaining professional composure.
The Bureau of Labor Statistics projects that registered nurse positions will grow about 6% between 2023 and 2033, with approximately 177,400 openings each year2. Nursing is one of the largest occupations in the United States, and the combination of growing demand and retirement-driven turnover creates consistent job opportunities across virtually every geographic region.
What Nobody Tells You About Nursing Requirements
The clinical schedule will take over your life. Clinical rotations often start at 6:00 AM and may include night shifts, weekends, and 12-hour days. You are expected to prepare care plans the evening before, perform during the clinical day, and complete documentation afterward. Working a part-time job during clinical semesters is extremely difficult.
The emotional toll is real and starts during clinicals. You will care for patients who are suffering, dying, or in crisis. Some students discover during clinicals that the emotional demands of nursing are not a good fit. This is a legitimate and important realization — better to discover it during school than after licensure.
Pharmacology requires pure memorization at scale. Drug names, classifications, mechanisms, dosages, side effects, interactions, and nursing implications for hundreds of medications. There is no shortcut. Flashcards, repetition, and daily review are how students survive pharmacology.
The NCLEX pass rate is the number that matters most about your program. Ask prospective programs for their NCLEX first-time pass rate. Programs with 90%+ rates are doing something right. Programs below 80% should raise questions about the quality of preparation you will receive.
After your BSN, specialization comes through experience and graduate education. Nurse practitioner (NP), certified nurse anesthetist (CRNA), clinical nurse specialist (CNS), and nurse educator roles all require master's or doctoral degrees. The BSN is the foundation, not the ceiling.
FAQ
How hard is nursing school compared to other majors?
Nursing is consistently rated among the most difficult undergraduate programs. The combination of heavy science coursework, clinical hours, and emotional demands creates a workload that exceeds most other majors. The difficulty is not primarily intellectual — it is the volume and simultaneous demands on your time, emotional energy, and physical stamina.
How long does it take to become a nurse?
Four years for a BSN, then passing the NCLEX-RN exam (typically taken within a few months of graduation). ADN programs take two years plus NCLEX. After licensure, most nurses complete a residency or orientation program (3-12 months) at their first employer before practicing independently.
What GPA do I need for nursing school?
Most competitive BSN programs require a minimum prerequisite GPA of 3.0-3.5, with some programs averaging admitted students at 3.6 or higher. GPA in science prerequisites (anatomy, physiology, microbiology, chemistry) is weighted most heavily. Overall university GPA matters less than your performance in the specific prerequisite courses.
Can I work during nursing school?
During prerequisite courses (first two years), many students work part-time. During clinical years (junior and senior), working is very difficult due to clinical schedules, care plan preparation, and study demands. Most nursing programs advise against working more than 10-15 hours per week during clinical semesters. Plan your finances accordingly.
What is the NCLEX and how hard is it?
The NCLEX-RN is the national licensing exam for registered nurses. It is a computerized adaptive test that adjusts difficulty based on your responses. The national first-time pass rate is approximately 87-89%2. Graduates of strong BSN programs with good study preparation typically pass on their first attempt. The exam tests clinical judgment and application of nursing knowledge, not rote memorization.
Is a BSN necessary, or can I start with an ADN?
You can start with an ADN and work as an RN while completing a BSN through an online bridge program. This path saves money upfront and lets you earn a nursing salary sooner. However, many hospitals now require BSN for new hires, and career advancement (management, specialization, NP programs) typically requires a BSN as the minimum. The long-term trend favors BSN as the entry credential.
