Preparing for a computer science degree in college starts with a strong high school curriculum. The most important subjects are mathematics and science, as they build the logical thinking and problem-solving skills essential for the field.
Excelling in core academic courses provides the foundational knowledge required to succeed in advanced CS topics. Many students also supplement their learning through online platforms like Khan Academy, Coursera, and edX to get a head start.
Building A Strong Foundation Early
A high school student aiming for computer science should focus on a curriculum that emphasizes analytical and quantitative skills. Colleges look for applicants who have challenged themselves with rigorous courses that demonstrate an ability to handle complex concepts.
This strong base not only makes college-level coursework more manageable but also opens doors to advanced placement and dual-enrollment opportunities. Platforms like Udemy, The Princeton Review, and FutureLearn offer excellent preparatory courses for standardized tests and introductory programming.
Mathematics: This is the most critical area. A sequence through Algebra I & II, Geometry, Trigonometry, and Pre-Calculus/Calculus is non-negotiable. Calculus, in particular, is a common college requirement for CS majors.
Sciences: Physics is highly valuable for its focus on applied math and problem-solving. Computer Science or Programming electives, if offered, provide a crucial introduction to coding logic and languages.
English & Communications: Strong writing and speaking skills are vital for documenting code, writing reports, collaborating in teams, and presenting ideas clearly—often an overlooked but critical part of a tech career.
Advanced Placement (AP) Courses: Taking AP Computer Science A (which focuses on Java) or AP Computer Science Principles provides a significant advantage. AP Calculus and AP Physics also demonstrate college readiness.
FAQs
Is computer science in high school necessary for a college major?
While not always a strict requirement, taking high school CS courses strongly demonstrates interest and provides a foundational advantage, making introductory college classes much easier.
What math should I be taking in high school for computer science?
Aim to complete at least Pre-Calculus by your senior year. Taking Calculus is a major advantage and is often an expected prerequisite for top university programs.
Can I start learning to code in high school without any classes?
Absolutely. Many free and paid resources are available online. Platforms like Codecademy, Khan Academy, and Udacity offer beginner-friendly coding tutorials in Python, Java, and web development.
Do colleges care about electives for a computer science application?
Yes. Electives like robotics, web design, or statistics show a proactive interest in the field and can strengthen your application beyond the core requirements.
What if my high school doesn’t offer AP Computer Science?
You can pursue the subject independently through online courses on edX or Coursera and take the AP exam as an external candidate, or focus on building a portfolio of personal programming projects.
Final Thoughts
Choosing the right high school subjects is the first strategic step toward a successful career in computer science. A focus on advanced mathematics, science, and available computer science courses will build the essential framework for your future studies.
For those looking to get ahead, the wealth of knowledge available through e-learning platforms like Coursera, Udemy, and edX provides an invaluable resource for personal growth and academic advancement, ensuring you are well-prepared for the challenges of a college program and beyond.
