What science classes are required in high school? How many years of science for college is ideal? What science classes do colleges require for STEM majors? These are some of the most common questions families face while planning high school course loads.
Whether you’re aiming for a competitive engineering school or a liberal arts college with strong science programs, understanding. This guide breaks it all down so you can build a strategic, standout science path.
Let’s start with the basics: most colleges expect students to complete at least three years of science in high school, including courses like biology, chemistry, and physics. However, for STEM admissions requirements, especially at top-tier or selective institutions, four years of science is strongly recommended and often expected.
This shows colleges you’re ready for the rigor of college science requirements and committed to your academic path. For future engineers, doctors or researchers, four years of science (including lab-based courses) can make a difference and help you stand out.
Check the admission websites of your target schools. MIT, Caltech and other top engineering schools often require or recommend more intensive science coursework than a liberal arts college.
If you’re considering a STEM major in college, you’ll want a robust foundation in core sciences—especially biology, chemistry and physics. These not only prepare you for your intended major but also fulfill most admission requirements.
Beyond the core three, electives can help you demonstrate academic breadth and interest.
While not all electives fulfill lab science requirements, they can enhance your narrative. For example, a student pursuing environmental engineering who takes Environmental Science and leads a sustainability initiative sends a clear, aligned message to admissions officers.
Advanced Placement (AP) science classes are a great way to show academic rigor, especially if you’re applying to selective colleges. Here’s a breakdown of the best AP science classes for college:
| Course | Best for Students Interested In |
| AP Biology | Pre-med, biology, life sciences |
| AP Chemistry | Pre-med, chemistry, pharmacology, engineering |
| AP Physics 1 & 2 | Engineering, physical sciences |
| AP Physics C | Engineering, physics (calculus-based) |
| AP Environmental Science | Sustainability, ecology, earth science |
| AP Psychology | Behavioral science, psychology (not lab-based in most schools) |
Not all AP science classes count as lab sciences for admissions. AP Psychology and Environmental Science may not meet lab science requirements depending on how they’re taught at your school.
When it comes to college admissions, science coursework matters—but it’s only one piece of the puzzle. Admissions officers review applications holistically, and they want to see how you engage with your interests outside the classroom.
Colleges are seeking students who not only take rigorous courses but also demonstrate curiosity, initiative and personal growth. Let your science interests come through in your activities, essays and recommendations—not just your transcript.
