“How Do I Choose an Engineering Major?”

Q: Hi Lisa — I’m a high school junior who loves math and science, but I have no idea which engineering major to pick. They all sound interesting but also confusing. How do I figure out which one fits me? And are there high school classes that match each major?

A:

You’re already ahead of the game by asking this now. Most students don’t realize how many types of engineering exist until they’re filling out college applications. The good news is you don’t need to have it all figured out today. Engineering majors share a common foundation — math, physics, problem‑solving — and many students switch majors once they discover what they enjoy most.

Below is a simple, no‑nonsense guide to the most common engineering majors, what they actually do, and which high school classes give you a taste of each one.

A Simple Guide to Engineering Majors (Without the Overwhelm)

Mechanical Engineering

What it’s about: Anything that moves. Cars, robots, engines, medical devices, HVAC systems, manufacturing equipment — mechanical engineers design and improve machines and systems.

You might like it if: You enjoy physics, building things, taking things apart, or wondering how everyday objects actually work.

High school classes that match: Physics, AP Physics, Calculus, Robotics Club, Project Lead The Way (PLTW) Engineering.

Civil Engineering

What it’s about: The built world — bridges, roads, buildings, water systems, transportation networks. Civil engineers design the infrastructure that communities rely on.

You might like it if: You’re drawn to architecture, city planning, sustainability, or solving problems that affect entire communities.

High school classes that match: Geometry, Physics, Environmental Science, AP Calc, Drafting, Architecture electives.

Electrical Engineering

What it’s about: Electricity, circuits, power systems, electronics, telecommunications. Electrical engineers design everything from power grids to microchips.

You might like it if: You’re curious about how phones, computers, or anything electronic actually works.

High school classes that match: Physics (especially electricity & magnetism), AP Physics, Computer Science, Calculus.

Computer Engineering

What it’s about: The intersection of hardware and software — processors, embedded systems, robotics, cybersecurity.

You might like it if: You like coding but also want to understand the physical machines behind the code.

High school classes that match: AP Computer Science, Computer Science Principles, Robotics, Calculus, Physics.

Chemical Engineering

What it’s about: Turning raw materials into useful products — pharmaceuticals, cosmetics, food, energy, materials, and more.

You might like it if: You enjoy chemistry labs, mixing things, or understanding how substances behave.

High school classes that match: Chemistry, AP Chem, Biology, Calculus, Environmental Science.

Biomedical Engineering

What it’s about: Engineering solutions for healthcare — prosthetics, imaging devices, biomaterials, medical robotics.

You might like it if: You love science but want to help people directly through medical innovation.

High school classes that match: Biology, Anatomy & Physiology, Chemistry, Physics, Robotics, AP Calc.

Aerospace Engineering

What it’s about: Aircraft, spacecraft, drones, propulsion systems, aerodynamics.

You might like it if: You’re fascinated by flight, space, or anything NASA‑related.

High school classes that match: Physics, Calculus, AP Physics, Computer Science, Engineering electives.

Industrial Engineering

What it’s about: Making systems more efficient — manufacturing, logistics, operations, human‑centered design.

You might like it if: You like organizing, optimizing, or improving processes.

High school classes that match: Statistics, Business electives, Computer Science, Calculus.

Environmental Engineering

What it’s about: Protecting the planet — water quality, air quality, waste management, sustainability systems.

You might like it if: You care deeply about climate, ecosystems, and environmental solutions.

High school classes that match: Environmental Science, Biology, Chemistry, AP Environmental Science, Geometry.

Materials Science Engineering

What it’s about: Understanding and designing the stuff everything is made of — metals, ceramics, polymers, composites, biomaterials, semiconductors. Materials engineers figure out how to make things stronger, lighter, more sustainable, or more functional.

You might like it if: You’re curious about what makes materials behave the way they do, or you’re fascinated by innovation in things like flexible electronics, medical implants, or sustainable packaging.

High school classes that match: Chemistry, AP Chem, Physics, Engineering electives, Environmental Science, Art (for design-minded students).

How to Choose (Without Stressing Out)

Here’s a simple way to narrow it down:

1. Start with the classes you enjoy most.

If physics lights you up → Mechanical, Aerospace, Electrical, Material Science.

If chemistry is your thing → Chemical, Biomedical, Material Science.

If you love coding → Computer Engineering.

If you’re drawn to cities, buildings, or the environment → Civil or Environmental.

2. Think about the problems you want to solve.

Engineering is ultimately about impact. What problems excite you?

3. Remember: you can switch.

Most engineering programs share the same first‑year courses. You’ll have time to explore.

Final Thought

Choosing an engineering major isn’t about predicting your entire future — it’s about choosing a starting point that feels interesting and energizing. Follow your curiosity, not the pressure to “get it right.” You’ll grow into the engineer you’re meant to be.
