I still remember starting my self-study journey in computer science in the summer of 2016, without any direction or knowledge of programming languages, data structures, or algorithms. After searching online, I discovered CS 61B by Prof. Josh Hug, which seemed like the best choice. Following the course schedule, watching recordings, and working through the materials, homework, and projects, I gained solid knowledge in Java, various important data structures, and algorithms within four months. I even included the course projects on my resume, which helped me secure internship interviews with companies like Dropbox, Indeed, and VMware. This success gave me the courage to continue my journey, eventually becoming a software engineer.
Today, as a senior software engineer, I still rely on the foundational knowledge, engineering skills, and coding philosophy I developed during that time, which continue to support my career growth.

Embarking on a journey to learn computer science on your own can be both exhilarating and daunting. With countless resources available, it’s challenging to find a course that provides a comprehensive and structured introduction to the field. If you’re a beginner looking for a top-tier educational experience, look no further than the open-sourced course CS 61B: Data Structures, offered by UC Berkeley.
Why CS 61B?
UC Berkeley is renowned for its rigorous academic programs and its contributions to computer science. CS 61B, a cornerstone of their undergraduate curriculum, focuses on data structures—a fundamental topic for any aspiring computer scientist. This course not only lays a solid foundation but also equips you with practical skills essential for tackling real-world problems.
Key Features of CS 61B
- Comprehensive Curriculum: CS 61B covers a wide array of topics, including arrays, linked lists, trees, graphs, and hash tables. You’ll also delve into algorithms for sorting and searching, and learn about performance analysis. This breadth of content ensures you gain a deep understanding of data structures, which are critical for efficient programming.
- Expert Instruction: The course is taught by some of the best educators in the field. Professor Josh Hug, known for his engaging teaching style, ensures that complex concepts are broken down into digestible pieces, making learning both enjoyable and effective.
- Hands-On Projects: CS 61B emphasizes practical application through a series of challenging projects. These projects not only reinforce theoretical knowledge but also enhance your problem-solving skills. By the end of the course, you’ll have a portfolio of work demonstrating your ability to implement and optimize data structures.
- Open-Source Accessibility: One of the standout features of CS 61B is its availability as an open-source course. You can access lectures, assignments, and exams for free, making it an ideal choice for self-learners. This accessibility removes financial barriers and allows you to learn at your own pace.
- Supportive Community: Although self-study can sometimes feel isolating, the CS 61B course is supported by a vibrant online community. Platforms like GitHub and Piazza host discussions where you can seek help, share insights, and collaborate with fellow learners. This sense of community can be incredibly motivating and enriching.
Detailed Project Highlights
CS 61B includes several substantial projects designed to reinforce and expand your understanding of data structures:
- Project 0: Awakening of Azathoth (AOA): This project involves creating a word-guessing game where players attempt to reveal a hidden word by guessing letters. Each correct guess reveals all instances of that letter in the word, while incorrect guesses decrease the remaining tries. The project tasks you with developing three AI “guessers” that can play the game and two “choosers” that select the words to be guessed, introducing a unique data structures challenge. Through this project, you will enhance your understanding of Java’s List and Map data structures, refine their problem-solving skills, and build a fully functional game that combines AI and algorithmic strategies.
- Project 1: Deques: This project focuses on implementing various types of double-ended queues (deques) using both linked lists and arrays. It’s a practical exercise in understanding and applying different data structures to solve the same problem.
- Project 2: NGordnet: This project involves building a word exploration and analysis tool inspired by Google Ngram Viewer. Students will develop a system to process and analyze large datasets of text to track word frequency and usage patterns over time. The project emphasizes implementing efficient data structures and algorithms to handle substantial data volumes, enhancing skills in Java programming, and applying practical data analysis techniques. By the project’s end, students will have created a functional tool capable of visualizing trends in word usage, showcasing their ability to manage and manipulate complex data sets effectively.
- Project 3: Build Your Own World (BYOW): This project challenges you to create a procedurally generated game world using Java. In this project, you should apply your knowledge of 2D arrays and random world generation techniques to design a dynamic and interactive game environment. The project emphasizes practical programming skills, requiring students to implement algorithms for terrain generation, character movement, and game state management. By completing BYOW, ou will gain hands-on experience with data structures and object-oriented programming, ultimately developing a fully functional game that showcases your ability to integrate complex systems and enhance user interaction.
Student Feedback
Don’t just take our word for it—here’s what some students have to say about their experience with CS 61B:
- Emily J.: “CS 61B was a game-changer for me. The projects are challenging but incredibly rewarding. They really pushed me to apply what I learned in lectures and develop a deeper understanding of data structures.”
- Michael T.: “The course materials are top-notch, and Professor Hug’s lectures are both informative and engaging. I felt well-supported throughout the course thanks to the active online community.”
- Sara K.: “As a self-learner, I appreciated the structure and depth of CS 61B. The open-source accessibility allowed me to study at my own pace, and the hands-on projects helped me build a solid portfolio that I can showcase to potential employers.”
How to Get Started
- Course Materials: Start by accessing the course materials on the CS 61B Course website. You’ll find lecture videos, slides, and reading materials.
- Course recommended textbooks:
- Programming Environment: Ensure you have a suitable programming environment set up. CS 61B uses Java, so you’ll need to install the Java Development Kit (JDK) and an Integrated Development Environment (IDE) like IntelliJ IDEA or Eclipse.
- Follow the Schedule: While you have the freedom to learn at your own pace, following the suggested schedule can help you stay on track. Dedicate regular time slots to watch lectures, complete assignments, and review materials.
- Engage with the Community: Join the course’s online communities on GitHub and Piazza. Don’t hesitate to ask questions and participate in discussions. Collaboration and peer support can significantly enhance your learning experience.
