Mastering Computer Science: It’s About Smart Learning, Not Just Hard Work!
I. Suggestions from Experienced Learners
-
Be Selective with Club Activities
If you attend an ordinary school and come from an average financial background, participate in club activities in moderation. On one hand, technical jobs rarely require these experiences, and companies won’t care about them. On the other hand, an average financial situation means you’ll likely rely on technical skills for your career, and club activities’ skills are mostly useless in the workplace. -
Focus on Core Courses
Pay close attention to several important foundational courses, such as data structures, computer organization, operating systems, and database principles. These courses are the core of computer science and will lay a solid foundation for your future learning and career. -
Learn a Foreign Language, Especially English
Many official documents and technical materials are in English, and many technical issues and bug descriptions are also in English. Mastering English will enable you to more efficiently access and understand technical resources. -
Master One Programming Language
At least become proficient in one of C/C++/Java. You can learn other languages when needed. Newer languages aren’t always better; mastering one core language can give you a competitive edge in your technical skills. -
Get Comfortable with Databases
Be proficient in at least one database and be able to write SQL statements well. Databases are the foundation of almost all software projects, and mastering them will at least secure you a basic job. -
Internships and Job Fairs
If you plan to work right after graduation, try to intern during your junior year or attend more job fairs. This will give you a clear idea of what skills are needed for job hunting. If possible, pursuing a master’s degree is still a good option. -
Write Technical Notes and Get Familiar with Linux
Learn to write technical notes and spend 0.5–2 hours learning Markdown syntax. If you have a few hundred dollars to spare, consider purchasing a cloud server like Alibaba Cloud to familiarize yourself with the Linux system. -
Avoid Gaming Addiction
Games are just numbers in a database. It’s fine to enjoy them occasionally, but getting addicted is a waste of time.
