Pharmacists don’t have one required undergraduate major. Most pharmacy schools accept applicants from any major as long as they’ve completed a specific set of prerequisite courses in science, math, and communication. In practice, the most common choices are biology, chemistry, biochemistry, and other health sciences, but that’s because those majors naturally overlap with the prerequisites, not because pharmacy schools demand them.
What Actually Matters: Prerequisites, Not Major
Pharmacy schools care far more about your prerequisite coursework than the name on your bachelor’s degree. The common prerequisites include General Chemistry I and II, Organic Chemistry I and II, Biology I and II, Anatomy and Physiology, Microbiology, Physics, Calculus, Statistics, English Composition, a communication or public speaking course, and a psychology or sociology course. That’s a heavy science load, which is why most pre-pharmacy students gravitate toward science majors where these courses are already built into the degree plan.
You can major in English, business, or political science and still get into pharmacy school. You’ll just need to fit all those science and math prerequisites into your schedule alongside your major’s own requirements, which can mean extra semesters or heavier course loads. Students who choose biology or chemistry as a major knock out many prerequisites automatically.
Most Popular Undergraduate Majors
The majors you’ll see most often among pharmacy school applicants are:
- Biology: covers the largest number of prerequisites in a standard four-year plan
- Chemistry or Biochemistry: strong overlap with general and organic chemistry requirements
- Pre-pharmacy: some universities offer a dedicated track designed to map directly onto pharmacy school prerequisites
- Biomedical Sciences or Health Sciences: broader programs that still include the core science coursework
Some students also major in public health, psychology, or exercise science. These still require supplementing with additional chemistry and biology courses, but they can strengthen a pharmacy application by demonstrating breadth.
You May Not Need a Full Bachelor’s Degree
Here’s something that surprises many people: a large number of pharmacy schools don’t require a four-year bachelor’s degree at all. The typical path involves two to four years of undergraduate study followed by four years of pharmacy school to earn a Doctor of Pharmacy (PharmD). Many students apply after completing just two or three years of college, as long as they’ve finished all the required prerequisites.
This means some pharmacists technically never earned a bachelor’s degree before starting their PharmD. They completed enough undergraduate coursework to meet admission requirements, then moved directly into the professional program. Whether this is possible depends on the specific school. Some programs do require a completed bachelor’s degree, while others only require the prerequisite courses and a minimum number of credit hours.
Direct-Entry Programs Skip the Major Entirely
A growing number of pharmacy schools offer “0-6” or direct-admission programs where students are accepted straight out of high school. In these programs, the first two years cover pre-pharmacy coursework within the same university, and students advance into the four-year professional phase once they’ve met all course and GPA requirements. There’s no separate undergraduate major at all.
Early assurance programs work similarly. Students enter from high school with a conditional seat in the PharmD program, complete their foundational science courses on an accelerated timeline, and transition into the pharmacy curriculum without needing to apply separately. According to the American Association of Colleges of Pharmacy, many schools now fill most of their PharmD seats through these direct-admission pathways.
GPA Expectations for Admission
Regardless of your major, competitive applicants typically need strong grades in their science courses. At UCSF’s pharmacy program, for example, the average entering student has a cumulative GPA of 3.50 and a science GPA of 3.38. These numbers vary by school, but they give a useful benchmark. Programs pay particular attention to how you performed in the prerequisite sciences, so earning a B-minus in organic chemistry matters more than your overall GPA in a less rigorous major.
One thing that’s changed recently: the Pharmacy College Admission Test (PCAT), which was once a standard part of the application, was retired in January 2024. No testing dates are being offered going forward. This shifts even more weight onto your undergraduate transcript, prerequisite grades, and the interview process.
Choosing a Major Strategically
If you’re certain about pharmacy school, a biology or chemistry major is the most efficient path. You’ll complete most prerequisites as part of your degree, leaving room for electives or a minor that interests you. If you’re less certain, choosing a versatile major like biology or health sciences gives you a fallback career direction while still preparing you for pharmacy school.
If you’re passionate about a non-science field, don’t let that stop you. Pharmacy schools genuinely accept students from all academic backgrounds. A psychology or business major who earns strong grades in the prerequisite sciences can be just as competitive as a chemistry major. The key is completing every prerequisite, performing well in those courses, and gaining some pharmacy-related experience through internships or volunteer work. Your major is a vehicle for getting the coursework done, not a gatekeeper to the profession.
