Load Up on STEM Courses

Take the most advanced math and science your school offers. Calculus and physics are non-negotiable.

Here is the truth about aerospace engineering programs: they do not slow down for you. From day one of your freshman year in college, you will be neck-deep in calculus-based physics, vector analysis, and differential equations. Students who loaded up on rigorous STEM courses in high school have a genuine advantage. Students who did not are playing catch-up from the first week.

This is not about padding your transcript. It is about building the foundation that every single aerospace engineering course sits on top of.

The AP Course Roadmap That Actually Matters

If your school offers Advanced Placement courses, here is the sequence that aerospace engineering programs want to see:

Mathematics (the backbone of everything):

AP Calculus AB — Take this by junior year at the latest. Derivatives and integrals are the language of aerospace engineering. Every equation you encounter in aerodynamics, orbital mechanics, and structural analysis assumes fluency in calculus.
AP Calculus BC — Take this senior year. BC covers series, parametric equations, and polar coordinates. A 4 or 5 on the BC exam can place you directly into Calculus III at most universities, saving you a full semester.

Physics (the application layer):

AP Physics C: Mechanics — This is the single most important AP course for aspiring aerospace engineers. It is calculus-based Newtonian mechanics: forces, energy, momentum, rotation. Every structures and flight mechanics course in college builds directly on this material.
AP Physics C: Electricity & Magnetism — Critical for avionics, control systems, and propulsion. If your school offers both Physics C courses, take both. Many schools teach them as a single year-long sequence.

Chemistry and Computer Science:

AP Chemistry — Materials science, propulsion chemistry, and thermodynamics all trace back to chemistry fundamentals. Rocket propellants, composite materials, fuel cells — you need to understand chemical bonds and reactions.
AP Computer Science A — Aerospace engineering is increasingly computational. Learning Java through AP CS A builds programming logic, but more importantly, it proves to admissions committees that you can think algorithmically.

The ideal four-year plan looks like this:

Freshman year: Honors Algebra II or Precalculus, Honors Biology, Honors Chemistry
Sophomore year: Precalculus or AP Calculus AB, AP Chemistry, Physics (regular or honors)
Junior year: AP Calculus AB or BC, AP Physics C: Mechanics, AP Computer Science A
Senior year: AP Calculus BC (or Multivariable Calculus if available), AP Physics C: E&M, AP Statistics or a second CS course

What If Your School Does Not Offer These Courses

Not every high school has AP Physics C or AP Calculus BC. That is a real obstacle, but it is not a dead end. Admissions committees at top engineering schools know that course availability varies. What they want to see is that you took the most rigorous path available to you — and that you found ways to go further.

Dual enrollment at a community college. This is the best alternative. Most states allow high school students to take courses at local community colleges, often for free or at heavily reduced tuition. Enroll in Calculus I and II, Calculus-Based Physics, or an introductory programming course. These are real college credits that transfer to most universities. Contact your school counselor and the community college admissions office to set this up — the process is usually straightforward.

Online AP courses. If dual enrollment is not an option, several platforms offer full AP courses online:

AP Classroom (College Board’s own platform) provides free course materials
edX offers AP-aligned courses from major universities
Johns Hopkins CTY and Stanford OHS offer rigorous online AP courses (these cost money, but financial aid is available)

Self-study for the AP exam. You can register to take any AP exam at a nearby school, even if you did not take the course. Students who score 4 or 5 on self-studied AP exams demonstrate exceptional initiative. Use Khan Academy (completely free) for Calculus and Physics C prep. MIT OpenCourseWare 18.01 and 8.01 are the actual MIT lecture series — they are harder than AP, which means if you can follow them, the AP exam will feel straightforward.

Why Each Subject Connects to Aerospace Engineering

This is not abstract. Here is exactly how your high school coursework maps to what you will do as an aerospace engineer:

Calculus is the language of change and motion. How does lift vary with angle of attack? How does thrust change as fuel burns? How does a satellite’s orbit decay over time? Every one of these questions is answered with calculus. In college, you will progress through Calculus III (multivariable), Differential Equations, Linear Algebra, and Partial Differential Equations. Students who arrive with BC credit start this sequence a semester ahead.

Physics C: Mechanics directly feeds into Statics, Dynamics, Mechanics of Materials, and Flight Mechanics — four core courses in every aerospace engineering curriculum. The concepts of free-body diagrams, moment of inertia, conservation of angular momentum, and work-energy theorem are not just revisited in college. They are assumed knowledge.

Physics C: E&M connects to circuit analysis, control systems, and avionics design. Modern aircraft and spacecraft are loaded with sensors, actuators, and control loops that require deep understanding of electromagnetic principles.

Chemistry appears in materials science (why carbon fiber composites behave differently than aluminum alloys), propulsion (combustion chemistry, specific impulse calculations), and thermal protection systems.

Computer Science is no longer optional. Modern aerospace engineers write simulation code, process flight test data, automate analysis workflows, and build digital twins. The industry has moved far beyond slide rules and hand calculations.

Coding: Start with Python and MATLAB

Beyond AP Computer Science, there are two specific tools you should start learning now:

Python is the industry workhorse. It is free, runs on any computer, and has enormous libraries for scientific computing (NumPy, SciPy), data visualization (Matplotlib), and even machine learning (TensorFlow, PyTorch). Aerospace companies use Python for data analysis, automation, and rapid prototyping. Start with the free Python course on Codecademy or the MIT 6.0001 course on edX.

MATLAB is the standard tool in aerospace engineering education. Almost every university aero program uses MATLAB for coursework in controls, signal processing, and numerical methods. Many high schools have MATLAB licenses through MathWorks’ academic program — ask your math or science teacher. If not, GNU Octave is a free, open-source alternative that runs nearly identical code.

A practical starting project: write a Python script that calculates the trajectory of a projectile with air resistance. This combines physics, calculus concepts (numerical integration), and programming in one exercise. It is the kind of thing that makes you genuinely better prepared, not just a line on a resume.

How Admissions Committees Evaluate Your Transcript

Top aerospace engineering programs receive thousands of applications from students with strong grades. Here is what differentiates the admits:

Course rigor matters more than GPA. An A-minus in AP Calculus BC is worth more than an A-plus in regular pre-calculus. Admissions officers at schools like Georgia Tech, Purdue, and MIT have said this explicitly and repeatedly. They want to see that you challenged yourself.

The upward trajectory matters. If you started high school in Algebra I and finished in AP Calculus BC, that progression tells a story of growth and determination. A student who started in Precalculus and ended in AP Calculus AB shows less range.

Consistency across STEM subjects matters. Taking AP Calculus but avoiding physics raises questions. Aerospace engineering programs want students who embrace the full spectrum of STEM rigor.

The number you need to hit: For the top 10 programs (MIT, Georgia Tech, Purdue, Michigan, Caltech, Stanford, CU Boulder, UT Austin, UIUC, Texas A&M), admitted students typically have a 3.8+ unweighted GPA, 4 or 5 on relevant AP exams, and strong standardized test scores in math.

Getting Ahead with Self-Study

If you have worked through the AP curriculum and want to go further, here are free resources that will put you ahead of most incoming freshmen:

MIT OpenCourseWare 18.02 (Multivariable Calculus) — This is the actual MIT course. Working through the problem sets will prepare you for Calc III better than almost anything else.
MIT OpenCourseWare 18.03 (Differential Equations) — If you can handle this before college, you are in rare company. Differential equations are the backbone of aerospace analysis.
Khan Academy — Excellent for filling gaps in any subject. The linear algebra series is particularly well done.
3Blue1Brown (YouTube) — The “Essence of Linear Algebra” and “Essence of Calculus” series build geometric intuition that textbooks often miss. This channel makes abstract math feel concrete.

The students who arrive at college with a head start on the math sequence have more room in their schedules for undergraduate research, design teams, and electives in specializations like autonomous systems or space mission design. That scheduling flexibility is a real, tangible advantage.

The Bottom Line

You cannot shortcut the math and science. Aerospace engineering is one of the most mathematically demanding undergraduate degrees, and the preparation starts now. Take the hardest courses available. Supplement with community college or online courses if needed. Teach yourself Python. Work through problems until the concepts stop being intimidating and start being tools.

Every hour you invest in STEM coursework now pays compound interest in college and beyond. Engineers with strong fundamentals do not just survive their degree programs — they lead design teams, publish research, and land the internships that launch careers.

Start today. Open Khan Academy or MIT OCW tonight. Work one problem set this week. Build the habit now, because the students who do are the ones who end up designing the next generation of aircraft and spacecraft.
