English/Writing Courses: Most programs require coursework demonstrating critical thinking and writing abilities, typically two semesters of writing-intensive courses.
If you’re missing multiple prerequisites, post-baccalaureate programs can provide a structured path to complete required coursework. These programs are specifically designed for career changers who hold bachelor’s degrees but need additional science coursework before applying to medical school.
Post-bacc programs typically take one to two years and can significantly strengthen your medical school application by demonstrating your commitment to the field and providing recent academic performance evidence.
Accelerated Bachelor of Science in Nursing (ABSN) programs have become increasingly popular pathways for career changers. These intensive programs allow individuals who already hold a bachelor’s degree in another field to earn their BSN and become registered nurses in 12-18 months.
Before entering an ABSN program, you’ll typically need to complete:
Anatomy and Physiology: Most programs require two semesters (Anatomy & Physiology I and II) with laboratory components. These courses must often be completed within the past 5-7 years.
Microbiology: One semester with lab is standard for nursing programs, covering bacteria, viruses, and infection control principles.
Chemistry: At least one semester of general chemistry or introduction to chemistry is typically required.
Nutrition: Many nursing programs require a nutrition course, often specifying it must be taught by a registered dietician.
Statistics or College Math: Mathematical reasoning and data interpretation skills are essential for evidence-based nursing practice.
Developmental Psychology: Understanding human development across the lifespan is crucial for patient care.
According to information about accelerated nursing programs in Pennsylvania, most ABSN programs require a minimum GPA of 3.0, with some requiring higher GPAs specifically in science prerequisites.
Online nursing prerequisite courses offer flexibility for working professionals making a career change. However, it’s crucial to verify that your target nursing program accepts online coursework, particularly for laboratory science requirements. Many programs prefer in-person lab courses to ensure hands-on learning.
Transitioning from another healthcare role to become a physician assistant requires completing specific prerequisites and documenting clinical experience. Research.com’s guide on RN to PA transitions explains that while nursing experience provides valuable preparation, additional coursework is typically necessary.
Most PA programs require:
Human Anatomy: Detailed study of human body structures
Physiology: Understanding how body systems function
Microbiology: Study of microorganisms and disease
General Chemistry: Foundational chemistry principles
Organic Chemistry: Often required or strongly recommended
Psychology: Understanding human behavior and mental health
Medical Terminology: Healthcare language and terminology
According to West Coast University’s RN to PA guide, most PA master’s programs require a minimum GPA of 3.0, with particular attention to science coursework performance.
Online prerequisite courses offer significant advantages for career changers who need to balance coursework with existing professional and personal responsibilities.
Online courses allow you to study on your own schedule, making it possible to complete prerequisites while maintaining your current employment. This flexibility is essential for career changers who need to continue earning income during their transition.
Many online programs offer accelerated course formats that allow you to complete prerequisites faster than traditional semester-long courses. Eight-week and six-week intensive courses can help you meet requirements and apply to graduate programs sooner.
Online prerequisite courses often cost less than traditional university courses while maintaining the same academic rigor. This affordability matters significantly when you’re investing in a career change and need to manage educational expenses carefully.
Choosing regionally accredited online courses ensures your credits transfer to graduate programs. The Council for Higher Education Accreditation (CHEA) recognizes accrediting organizations that maintain high educational standards.
Selecting appropriate prerequisite courses requires research and strategic planning:
Every graduate program has specific prerequisite requirements. Before enrolling in any courses, thoroughly research the programs you plan to apply to. Review their websites, contact admissions offices, and verify course requirements to ensure you’re taking the right classes.
Many healthcare programs require that prerequisite courses, particularly science courses with labs, be completed within 5-7 years of your application. If your coursework is older, you may need to retake certain classes.
Science courses typically require laboratory components. Confirm whether your target programs accept online labs, virtual labs, or require traditional in-person laboratory work. Most medical schools prefer in-person labs for prerequisite courses.
Some courses must be taken in sequence. For example, you need to complete General Chemistry before Organic Chemistry, and Anatomy typically precedes Physiology. Plan your course sequence carefully to avoid delays.
Returning to school for prerequisite courses represents a significant investment. Understanding your options can help make this transition more affordable.
If you enroll at least half-time in a degree or certificate program, you may qualify for federal student loans through FAFSA (Free Application for Federal Student Aid). Graduate students can access Direct Unsubsidized Loans and Grad PLUS loans to help cover educational expenses.
Many employers offer tuition reimbursement programs for employees pursuing additional education. Check with your human resources department about available benefits, even if you’re changing career fields.
Most institutions, including prereqcourses.com, offer flexible payment plans that allow you to spread course costs over several months, making prerequisites more manageable financially.
Some organizations offer scholarships specifically for career changers entering healthcare fields. Research opportunities through professional associations, healthcare organizations, and educational foundations.
Understanding the time commitment helps you plan your career transition realistically:
Taking one or two courses per semester while maintaining full-time employment typically allows you to complete 4-6 prerequisite courses per year. Most career changers need 6-12 months to complete all requirements at this pace.
If you can dedicate yourself to full-time study, you can complete most prerequisite requirements in one to two semesters. Accelerated programs compress this timeline further, with some courses completed in just 6-8 weeks.
Formal post-baccalaureate programs typically take 1-2 years to complete and include career advising, MCAT preparation, and linkages to medical schools—valuable support for career changers.
Your performance in prerequisite courses significantly impacts your graduate school application. Career changers often need to demonstrate strong academic capability, especially if their previous degree wasn’t in science.
