Key Courses to Take
Top Programs
MIT
BSComputer Science & Engineering (Course 6-3)
Consistently #1 or #2 for CS. Excellent research and industry connections. Extremely competitive admissions.
Top 3 CS program globally
Stanford University
BSComputer Science
Silicon Valley's backyard. Unmatched startup culture, VC access, and network. Many big tech founders are alumni.
Top 3 CS program globally
Carnegie Mellon University
BSComputer Science (SCS)
Often ranked #1 specifically for CS. Strongest systems, AI, and security programs. Exceptional industry placement.
#1 pure CS program by many rankings
UC Berkeley
BSElectrical Engineering & Computer Sciences (EECS)
World-class public university. Berkeley alumni are everywhere in big tech. Strong research and startup scene.
Top 5 CS program, top public university
University of Illinois Urbana-Champaign (UIUC)
BSComputer Science
Best CS program among large public universities. Outstanding career placement — recruiters flock here. More affordable than private peers.
Top 5 CS, best value for CS
An MS in CS can help you break into research teams or move from entry to mid level faster. Not required. Many top engineers skip it entirely. A PhD is only worth it if you want to work on foundational AI research.
School to Career
The stuff you're learning right now directly applies to this career — often in ways your teacher hasn't mentioned.
Courses That Matter
AP Computer Science A
This is the most direct preview of your job. Object-oriented programming, loops, arrays — these are daily tools. If you enjoyed AP CS A, software engineering will feel natural.
AP Computer Science Principles
Gives you the big picture of how the internet works, how data is represented, and why algorithms matter. More conceptual than AP CS A, but great context for why your future job exists.
Algebra II
Functions, variables, and solving for unknowns are the grammar of programming. Every time you write `f(x) = x + 1` in math class, you're writing what programmers call a function.
Pre-Calculus / Calculus
If you go into machine learning, calculus is used constantly — particularly derivatives (how a model 'learns' by adjusting to errors). Even if you don't, the logical thinking Calc trains is invaluable.
AP Statistics
A/B testing — how tech companies decide which version of a feature to ship — is applied statistics. Every product decision at Google or Meta involves hypothesis tests you learned in Stats class.
Discrete Mathematics
Logic, sets, graphs, and proofs are the math underlying algorithms. The algorithm interview questions you'll face in job applications come directly from this.
Physics
Physics trains you to break complex systems into components and reason about them — exactly what engineers do when designing software architecture.
Extracurriculars That Count
Robotics Club (FRC, FTC, VEX)
The best preview of real engineering work: a hard problem, a deadline, a team, and hardware that doesn't cooperate. Many big tech engineers cite robotics as what convinced them this was their path.
Competitive Programming (USACO, LeetCode contests)
Directly trains the algorithm problem-solving that is literally tested in big tech job interviews. If you compete in USACO, you already think like a software engineer.
Math Team / AMC / MATHCOUNTS
Builds the pattern recognition and structured thinking that separates good from great engineers. Many top SWEs were serious math competitors.
Build personal projects or apps
The single best thing you can do. Build an app, a game, a website — anything. The habit of building for fun is the clearest signal to future employers and to yourself.
“If you've ever stayed up way too late debugging your code or building something just to see if you could — this career will feel like getting paid to do what you'd do for free.”
Who Got Here Before You
Linus Torvalds
Creator of Linux and Git
Built the Linux kernel at 21 as a hobby project. It now runs 97% of the world's servers, all Android phones, and every supercomputer on the Top500 list. Also invented Git — the tool every engineer uses daily.
Margaret Hamilton
Director of Software Engineering, NASA Apollo Program
Wrote the onboard flight software for the Apollo 11 moon landing. Coined the term 'software engineering.' Her code had to be perfect — there was no patching it 240,000 miles from Earth.
Jeff Dean
Google Senior Fellow, Head of Google AI
Designed the core infrastructure that makes Google Search fast — systems processing billions of queries daily. Regarded by many as the most impactful software engineer of his generation.
Where This Can Take You
Where This Career Can Take You
Software Engineer at a Hedge Fund
Move from building consumer products to building trading systems. Compensation jumps significantly. Much smaller teams, more ownership, more pressure.
Trigger: Demonstrated interest in finance + strong algorithms skills; often happens 2-4 years in
Technology Consultant
Leave engineering to become a strategic advisor. Trade deep technical work for variety, travel, and client-facing roles. Often requires an MBA.
Trigger: Top MBA program (HBS, Wharton, Booth, Kellogg) — typical path for engineers wanting to pivot to strategy
