If your teen is even thinking about pre-med, it is easy to feel excited and load up their high school years with college-level sciences. Many parents wonder about using AP vs dual enrollment, and most want their teens to complete as many college-level sciences as possible during high school. In reality, your student has to complete high school and a bachelor’s degree before they begin medical school, so the on-ramp is long.
This post will help you understand the essential pre-med science pathway, how AP and dual enrollment fit in, and how to plan high school coursework that builds true scientific mastery without racing ahead too soon.
The Core Premed Science Sequence
No matter what the student majors in or where they eventually apply, admission into medical school requires the student to have completed these eight college courses:
Biology (with Lab)
- General Biology I with Lab
- General Biology II with Lab
Chemistry (with Lab)
- General Chemistry I with Lab
- General Chemistry II with Lab
Physics (with Lab)
- General Physics I with Lab
- General Physics II with Lab
Advanced Chemistry
- Organic Chemistry I with Lab
- Biochemistry (lab requirements vary)
These 8 form the student’s science GPA and provide essential knowledge for the MCAT (admissions exam) and the foundation of medical science.
Why AP and CLEP Science Exams Are Not Recommended for Premeds
AP exams and CLEP exams do not award grades. Medical schools want to see real graded college science courses. Exam-based credit also creates gaps in content that the MCAT depends on. Many medical schools do not accept exam credit for prerequisites, and some committees default an AP or CLEP substitution to a C or require the student to retake the course. While AP “courses” can be excellent, the exams that generate college credit in science can create problems. This is not a case of getting college CREDIT on your undergraduate degree; you will. This is the case of looking ahead at graduate school ADMISSIONS and your student not having the requirements to qualify to apply. For most students, AP and CLEP are great tools. For premed students, they are not. If you want to use AP and CLEP to save money on undergrad (a great idea!) be sure to do so in other general education courses or electives that won’t be reviewed for medical school admissions.
Excellent AP & CLEP options include:
- American Government
- History of the United States
- Introductory Sociology
- Macroeconomics
- Microeconomics
- Western Civilization
- American Literature
- English Literature
- Accounting
- Marketing
- Management
- Any non-English language
CC vs University for Dual Enrollment
There is a list. Each year the Association of American Medical Colleges publishes a list of every medical school and whether or not they accept coursework taken through a community college. You can find examples of medical schools that absolutely do NOT take any coursework from the community college (ex. George Washington University) but for the most part, it’s acceptable. Beyond that, you’ll read heavily debated arguments for why it’s probably not the best way to learn science, but if you have access to free or low-cost dual enrollment in high school, an excellet way to learn science and avoid the debate is to use the “Intro to…” sciences to start learning the content.
Do Not Rush the Premed Sciences During High School
This section is essential and often misunderstood.
A non-HS4CC student typically completes:
- High school Biology
- High school Chemistry
- High school Physics
and then takes the full pre-med science sequences in college. This is normal, expected, and fully prepares them for the MCAT.
When families use dual enrollment to replace high school science, they “kill two birds with one stone,” but they also potentially lose a full round of foundational practice. Biology, chemistry, and physics are not subjects students should experience only once if they plan to pursue pre-med. Repetition creates mastery. Mastery raises grades. High grades raise the science GPA.
If a student has never studied science before, they should start with high school Biology, Chemistry, and Physics. These are critical developmental courses. If their schedule allows, they can also take the “Intro to” dual enrollment versions later in high school:
- Introduction to Biology with Lab
- Introduction to Chemistry with Lab
- Introduction to Physics with Lab
- Microbiology with Lab (optional)
These intro classes provide an excellent intermediate opportunity to strengthen their foundation before taking the full General Biology, Chemistry, and Physics sequences during undergrad. In a lot of cases, the student can still use these courses as electives in their degree. Since your teen will need electives, this is a win-win. Then, in college, they will take the actual pre-med sciences, complete with grades, labs, and the depth needed for the MCAT.
Why Timing Matters
Premed sciences taken too early lose their value. These courses should be fresh before MCAT study. Taking core sciences several years before college can weaken test readiness and reduce the student’s confidence. The right sequence protects both mastery and timing.
Final Thoughts
Most teens who express interest in medicine will not ultimately apply to medical school, which is why homeschool parents rarely hear accurate advice about timing. The best long-term plan is to build a strong science foundation in high school, use dual enrollment intros thoughtfully if appropriate, and save the full premed sequences for college. This approach keeps the path open, supports deeper learning, and creates the strongest academic profile for future medical school applications.
