You’re scrolling through the list of requirements for your dream nursing program, and there they are: Anatomy & Physiology I & II, Microbiology, Chemistry. A pit forms in your stomach. You’ve heard the whispers, the war stories from other students. It leads to one persistent, nerve-wracking question: Are nursing prerequisites hard? It’s the question I get asked most often by aspiring nurses, and if you’re asking it, you’re already on the right track.
This isn’t a simple yes or no. The difficulty depends on your background, your study habits, and frankly, how you define “hard.” But let’s be honest—the science prerequisites required for nursing school are challenging. They are designed to be. This guide will break down why they’re hard, which ones present the biggest hurdles, and give you an actionable plan to not just survive them, but to thrive.
The Short Answer: Yes, They Can Be. But “Hard” is Relative
Let’s tackle the primary question head-on. Yes, your pre-nursing courses can be incredibly difficult. But it’s crucial to understand what makes them hard. For most students, it’s not about being a genius; it’s about managing a massive volume of information.
Think of it this way: succeeding in these courses is less like climbing a sheer cliff face and more like running a marathon. You don’t need to be a superstar athlete to finish, but you absolutely need a training plan, discipline, and endurance. The “hardness” comes from the sheer amount of new terms, concepts, and details you must learn, retain, and apply under a strict deadline.
Clinical Pearl: The GPA you earn in these prerequisites is often the single most important factor in your nursing school application. This adds a layer of pressure that makes the challenge feel even more intense. Treat every science course like it’s the most important one you’ll ever take.
The cornerstone courses—are nursing prerequisites like A&P and Micro—act as the language of medicine. Without a strong grasp of them, you’ll struggle in nursing school and, more importantly, you risk making unsafe decisions as a future nurse. This academic rigor is your first shield in protecting your future patients.
The Usual Suspects: A Deep Dive into the Hardest Nursing Prerequisites
While every student has their strengths and weaknesses, a few courses consistently rise to the top of the “most challenging” list. Let’s break them down.
Anatomy and Physiology (A&P) I & II
For many, A&P is the king of all prerequisites, often spanning two intense semesters.
The Hurdle: It’s a three-headed monster. First, there’s the sheer volume of information—hundreds of bones, muscles, nerves, and cellular processes. Second, it’s a new language. You’re learning Latin and Greek roots that form the basis of medical terminology. Third, it requires spatial reasoning. You can’t just memorize what the brachial plexus is; you have to be able to visualize its path and function.
Imagine you’re a nurse on a neuro floor. A patient reports new numbness and tingling in their left arm. You need to instantly access that A&P knowledge—connecting the symptom to a specific dermatome, the corresponding spinal nerve, and potentially a problem in the cervical spine. Your A&P course is building that exact mental map.
Pro Tip: Don’t just study flashcards. Draw the structures. Draw them again. Then, draw them from memory while explaining their function aloud. This process of active recall and kinesthetic learning cements the information far better than passive review.
Microbiology
Microbiology is fascinating but notoriously tricky for pre-nursing students.
The Hurdle: You’re studying life forms you can’t see. This abstract nature makes it difficult to grasp. Furthermore, it requires understanding complex metabolic pathways and life cycles of bacteria, viruses, fungi, and parasites. The final challenge is connecting this unseen world to the very visible world of infection control and disease.
Common Mistake: Viewing Micro as just a bunch of facts to memorize. In reality, it’s a “why” course. Why do we wash our hands for 20 seconds? Why are immunocompromised patients at higher risk? Why does this antibiotic work for that infection? If you focus on the “why,” you’ll learn how to think like a nurse.
Think about the principles of sterilization and isolation precautions you’ll use every day. That knowledge was born in a microbiology lab. Mastering this material isn’t about passing a test; it’s about understanding how to stop the spread of infection and save lives.
Chemistry
Whether it’s a general chemistry course or a combined organic and biochemistry (O-Chem/Bio-Chem), it’s often a source of major anxiety.
The Hurdle: Chemistry is highly conceptual and builds on itself. If you don’t understand moles and stoichiometry in week three, you will be lost when you get to acid-base balance in week eight. It often feels the most disconnected from the hands-on world of nursing, which can decrease motivation.
However, this course is a crucial piece of the puzzle. It’s the foundation for understanding pharmacology. The way a drug dissolves, binds to receptors, and is metabolized by your body—it’s all chemistry. A strong foundation here prepares you to be a nurse who truly understands how and why medications work, not just one that can administer them.
Why It Feels So Overwhelming (Beyond the Coursework)
The academic challenge is only one part of the equation. The psychological pressure surrounding these pre-nursing courses is immense, and acknowledging it is the first step toward managing it.
The GPA Tightrope
You’re not just trying to pass; you’re often trying to earn an A. With many nursing programs using a competitive admissions process, every single point matters. A B in a prerequisite course can feel like a catastrophe when you’re aiming for a 4.0 to increase your chances of acceptance. This GPA pressure transforms motivation from a love of learning into a high-stress performance.
Juggling Life, Work, and School
Let’s be real: many pre-nursing students aren’t 18-year-olds with only one job. You might be working a full-time job, raising a family, and dealing with life’s other responsibilities. Balancing a 15-20 hour per week course load on top of that is a Herculean task. The exhaustion is real, and it directly impacts your ability to study effectively.
Your Action Plan: 7 Proven Strategies to Ace Your Nursing Prerequisites
Enough about the problem. Let’s talk about the solution. Passing your pre-nursing courses isn’t about being the smartest person in the room. It’s about being the most strategic. Here’s your action plan.
- Embrace Active Recall, Not Just Rereading. Rereading your notes is comforting but terribly ineffective for long-term memory. Instead of passive review, force your brain to retrieve information. Cover up a diagram and try to label it. Use a whiteboard to write out a process from memory. Explain a concept out loud to your dog. The struggle of recall is what builds neural pathways.
- Form a Study Group (The Right Way). A bad study group is just a social hour. A good one is an academic weapon. Find 2-4 dedicated students. Come prepared with questions. Take turns teaching each other concepts. If you can teach it, you know it.
- Treat Your Lab Like Your First Patient. Don’t just go through the motions in lab. See it as the first step in your clinical training. When you’re dissecting a sheep brain in A&P or staining bacteria in Micro, imagine the real-world application. This mindset shift makes the material more meaningful and memorable.
- Master Your Time Management. You cannot cram for these courses. Use a planner. Schedule your study sessions like you would a class. The Pomodoro Technique (25 minutes of focused work, 5-minute break) is fantastic for long study days. Block out time for school, work, family, and rest.
- Go to Office Hours—Early and Often. Your professors and TAs are an incredible resource. Don’t wait until you’re failing to visit them. Go early in the semester with a list of specific questions. It shows initiative and helps you clear up confusion before it snowballs.
- Connect the “Why.” When you learn something new, immediately ask yourself: “Why does a nurse need to know this?” How does understanding the krebs cycle help you understand sepsis? How does memorizing the cranial nerves help you do a neurological assessment? This creates powerful memory hooks.
- Protect Your Mental Health. Burnout is the enemy of success. Get enough sleep. Eat real food. Move your body. Make time for friends and hobbies. If you’re feeling overwhelmed, reach out to your school’s counseling services. Taking care of yourself isn’t a luxury; it’s a prerequisite for success.
Key Takeaway: Success in your pre-nursing courses comes down to strategy, not just innate intelligence. Active learning, consistent effort, and a strong support system are your greatest assets.

Frequently Asked Questions (FAQ)
Q1: Can I realistically work full-time while taking my hardest nursing prerequisites? It’s incredibly difficult and not recommended for most. The general rule of thumb is 2-3 hours of study for every one hour of class time. A full science course load can quickly become a 40-50 hour/week commitment just for school. If you must work, try to reduce your hours or consider taking only one difficult science class at a time.
Q2: What if I fail a prerequisite class? Is my nursing dream over? Absolutely not! It’s a setback, not a deal-breaker. Many students retake a course and do much better the second time. Check with your target nursing schools about their policy on retakes—some will only count the higher grade, while others average them. Use it as a learning experience to refine your study strategies.
Q3: What is the single best study tip for A&P? Do not separate anatomy from physiology. As you learn the name and location of a structure (anatomy), immediately learn its function and role in a larger system (physiology). For example, when you learn the parts of the nephron, learn the function of each part in filtering blood and forming urine at the same time. They are two sides of the same coin.
