As a high-school senior, how should I go about learning different specializations in Computer Science?

I'm someone who is currently a senior in high school. I spent time learning about programming (writing code using Python and Java) and web development (HTML, CSS) for four years. I love spending time with those topics, but I recently explored topics like machine learning and computer systems engineering. I'm planning to study Computer Science at a four-year university, and I wonder what's the best way to explore specializations in computer science?

Prashanth’s Answer

Great question! Just like any other area, Computer Science is a big, exciting field. Programming is just the starting point, the base of the mountain. But there's so much more to explore! Keep your mind open and ready for adventure. As you progress through your studies, you'll dive into a variety of fascinating topics. You'll explore distributed systems, cybersecurity, cryptography, computational sciences, computer networks, data science, and even AI. As you get to know these areas, you'll likely find yourself drawn to one or more of them. That's your passion starting to show! Don't be shy to reach out to people who have walked this path before, or who are just starting to explore areas you're interested in. Their perspectives can be incredibly valuable. It's a big world out there in Computer Science, and I can't wait for you to start exploring!

Atul’s Answer

While you're still in high school, it's too early to narrow down your focus to a specific field. Instead, concentrate on becoming proficient in various languages. Once you step into college, you'll find a plethora of specialized courses available for you to explore. Consider the possibility of a dual major, like pairing Computer Science with Computer Engineering or an Electrical Engineering degree. This combination will provide you with a broad understanding of both hardware and software. Plus, it opens up opportunities for you to work in either pure software development or in a role that combines hardware design with software.

Hi Tyler!

Given your interest in exploring specializations in CS, here are some steps you can take:

1. Online Courses & Tutorials

There are numerous online platforms that offer free and paid courses in different areas of CS:
Coursera: Offers courses on Machine Learning, Data Science, Artificial Intelligence, and more.
edX: Provides courses from top universities on a range of CS topics.
Udacity: Known for its "Nanodegrees" in areas like Machine Learning Engineer, Data Analyst, etc.
Codecademy: An interactive platform that offers courses in a variety of programming languages.

2. Participate in Coding Challenges & Hackathons

Participating in coding challenges and hackathons can expose you to real-world problems. This will not only give you hands-on experience but will also allow you to explore different areas of CS. Websites like HackerRank, CodeSignal, and LeetCode host regular coding challenges.

3. Read Books & Research Papers

Books and research papers are a great source to dive deep into a topic. For instance, you can start with books like "Pattern Recognition and Machine Learning" by Christopher Bishop for machine learning and "Computer Networks: A Systems Approach" by Larry Peterson and Bruce Davie for computer systems.

4. Connect with Professionals

Networking with professionals through platforms like LinkedIn can provide insights into what specializations might be a good fit for you. You can also reach out to your professors or university alumni for guidance.

5. Internships & Work Experience

Internships provide practical experience and a glimpse into a specific field. Look for internships in different areas of CS to understand what working in that specialization would be like.

6. University Courses

When you get to university, take a variety of CS courses. Most universities offer a broad range of courses that cover different specializations. This will also give you an idea of what you like and what you're good at.

Remember, exploring is about finding what you enjoy and where your strengths lie. It's okay if you don't find your specialization right away!

I hope this helps!

Katherine’s Answer

Hi! I recommend finding a side project you can work on and test out different technologies and languages! It's a low stakes but impactful way that you can take control of your own learning. Find something that you want to use in your everyday life (an app that texts you whenever your laundry is done?, a timer app for something specific you want to time?)

Explore what you're interested in learning and put it into practice!
