The average high school student takes 6-7 classes per semester. The students who get into their first-choice college — or land internships before graduation — usually take one more thing nobody assigned them. That's not a knock on school; it's just how competitive the landscape has shifted. The courses high schoolers take outside the standard curriculum now show up on applications, portfolios, and LinkedIn profiles in ways that matter to admissions officers and recruiters alike.
This guide covers what kinds of courses are actually worth your time, how to pick one that fits your goals, and specific recommendations you can start this week.
Why the Courses High Schoolers Take Outside School Matter
Colleges receive applications from thousands of students with identical GPAs and test scores. What separates candidates at the margin is usually self-directed learning — evidence that you pursued something because you were genuinely curious, not because it was required.
Online courses give high schoolers something traditional school rarely offers: the ability to learn at the pace of the real world. A 17-year-old who has completed a Figma design course or a project management certification is already operating at entry-level professional speed. That's not hypothetical — employers increasingly hire high school graduates (and college freshmen) for part-time roles in tech, design, and marketing based on verifiable skill credentials, not just grades.
There's also a practical signal effect. Completing a structured online course — even a short one — demonstrates initiative, follow-through, and the ability to manage your own learning. Those are traits colleges and employers claim to want, and a course certificate is one of the few ways to actually document them.
What Courses Should High Schoolers Take? Choosing by Goal
The best course depends entirely on what you're trying to accomplish. There's no universal answer, but there are useful categories.
For Students Headed into Tech or Computer Science
If you're planning to study CS, software engineering, or anything adjacent, getting a head start on industry-relevant concepts pays double dividends: you'll write better college essays with real technical vocabulary, and you'll hit freshman year already ahead of peers who've only done AP CS. Courses covering software architecture, systems design, and back-end development are particularly valuable because they're rarely taught in high school but are core to any CS degree.
For Students Interested in Design, Product, or Startups
Design thinking and prototyping tools are now entry points to careers in UX, product management, and entrepreneurship. Figma has become the industry standard for UI/UX design, and knowing it as a high schooler puts you in a genuinely rare position — most adults in the field learned it on the job. A solid Figma course can translate directly into freelance work, portfolio pieces for art/design college programs, or a strong hook in a startup application.
For Students Focused on Leadership, Extracurriculars, or College Prep
Not every course needs to be technical. High schoolers who hold leadership roles — student council, sports captains, club presidents — often have real responsibilities but no formal training in how to collaborate, negotiate, or manage a team. Courses in leadership and teamwork give you frameworks that make you measurably better at these roles, and they give you language to describe your impact in college essays and interviews.
For Students Who Want to Build Academic Performance
Some high schoolers aren't looking to pivot careers — they just want to perform better academically and handle pressure more effectively. Courses on high performance, productivity, and goal-setting are underrated in this age group. They teach the meta-skills (focus, deliberate practice, recovery from failure) that compound across every class and activity you're already doing.
Top Courses for High Schoolers to Take Right Now
These are real courses available on major platforms, selected for relevance, accessibility, and practical value for high school students.
Create High-Fidelity Designs and Prototypes in Figma (Coursera)
Figma is the industry-standard design tool used at Google, Apple, Airbnb, and virtually every funded startup. This Coursera course teaches you to create polished, professional prototypes from scratch — the kind of work you can put directly into a portfolio. For high schoolers interested in design, UX, or tech product roles, finishing this course puts you ahead of most college students.
High Performance Collaboration: Leadership, Teamwork, and Negotiation (Coursera)
Offered through Northwestern University on Coursera, this course covers the real mechanics of leading teams, resolving conflict, and negotiating outcomes — skills that show up constantly in student government, clubs, sports, and group projects, but are almost never taught directly. High schoolers in leadership roles will find it immediately applicable, and the credential is credible enough to list on college applications.
The Complete Guide to Activating High Performance (Udemy)
This course addresses the performance side of high school life — how to build focus, manage energy, and execute under pressure. It's practical rather than motivational, covering evidence-based approaches to study habits, goal-setting, and mental recovery. Students juggling academics, athletics, and extracurriculars get the most out of it.
Microservices: Designing Highly Scalable Systems (Udemy)
For high schoolers serious about software engineering or computer science degrees, this course introduces systems architecture at a level most college juniors haven't reached yet. It covers how large-scale software is actually built — the kind of knowledge that makes a difference in technical interviews and CS program applications. Best suited for students who already have some programming experience.
How to Get the Most Out of Any Course You Take
The completion rate on self-paced online courses is notoriously low — estimates range from 5% to 15% depending on the platform. That means finishing a course is itself a differentiator. A few habits that help:
- Block time like it's a class. Treat your course hour the same as a scheduled class period. Unscheduled learning gets pushed by everything else.
- Do the projects, not just the videos. Platforms reward passive viewing with progress bars. Actual skill comes from the assignments, case studies, and projects. Those are also what you'll reference in interviews and applications.
- Save your completion certificate immediately. Download it, add it to Google Drive, and screenshot it. Platforms change and accounts expire. You want the credential to survive.
- Write one paragraph about what you learned. Before you move on, draft a 3-4 sentence summary of what the course taught you and how you applied it. This is the raw material for your college essay bullet point or resume line.
FAQ
What courses should high schoolers take to prepare for college?
It depends on your intended major and gaps in your current skillset. Tech-focused students benefit most from hands-on courses in design, programming, or systems thinking. Humanities students get significant value from writing, research, and leadership courses. The most universally useful are those that build skills your current school doesn't offer — that's what signals genuine initiative to admissions offices.
Are online courses worth it for high school students?
Yes, provided you finish them and can demonstrate what you learned. A completed course from Coursera or Udemy — especially one with a project or certificate — is a concrete credential. A half-finished course is not. The platform matters less than the completion and what you built during it.
Can high schoolers take Coursera or Udemy courses?
Yes. Both platforms allow students under 18 to enroll with parental consent (Coursera's terms require users to be 13+, Udemy 18+ or with parental permission). Most courses have no prerequisites beyond basic computer literacy. Coursera's financial aid program also makes many courses free if cost is a barrier.
Do online courses help with college admissions?
They can, especially when they're relevant to your stated area of interest and you can speak to them specifically in interviews or essays. Admissions readers are skeptical of padded activity lists, but a technical course with a portfolio project or a verifiable certificate from a university-affiliated program (like Coursera's Northwestern or Duke offerings) carries real weight. Quantity matters less than specificity — one course you can talk about intelligently beats five you barely remember.
How many courses should a high schooler take at once?
One at a time, completed before starting the next. The mistake most students make is enrolling in several courses simultaneously and finishing none of them. A single completed course with a real output (a Figma prototype, a project repo, a written analysis) is worth more than five unfinished enrollments.
What's the best free course for high schoolers?
Coursera's audit option lets you access most course content for free (you pay only if you want the certificate). For high schoolers on a budget, auditing a course from a top university — especially anything from Northwestern, Stanford, or Duke — gives you the learning without the cost. If the certificate matters for your application or portfolio, the cost is usually $49–$79 one-time, which is often worth it.
Bottom Line
The courses high schoolers take outside of school are increasingly the ones that define their college and early career trajectories. Traditional transcripts are nearly identical across competitive applicants; self-directed credentials and demonstrated skills are what separate them.
If you're not sure where to start, pick based on your most concrete near-term goal. Applying to design or product programs? Start with Figma. Planning a CS degree? Pick up the microservices architecture course to get a head start on systems thinking. Heading into a senior year with a lot of leadership responsibilities? The Northwestern collaboration course will pay off immediately in how you run meetings and manage team conflict.
The best course isn't the most prestigious one — it's the one you'll actually finish and be able to talk about a year from now.
