To master computer science for your career, you’ll want to learn different tools and skills. Live online or in-person classes are among the best learning options for computer science students.
Live computer science courses offer a variety of benefits. Students can get real-time answers to their questions, and live courses are both hands-on and interactive in most cases. For those who cannot commute to an in-person computer science class, live online computer science courses can be just as beneficial. Noble Desktop’s Full Stack Web Development Certificate is an example of one such program, available both in-person and online.
Another attractive option for computer science beginners is the on-demand or self-paced training model. On-demand computer science courses typically require a small fee or subscription to a particular platform, though some are available free of charge. Featured computer science topics range from building Android apps to JavaScript and Ruby on Rails.
While they may not offer the same level of engagement as live or on-demand classes, free seminars, tutorials, and blog posts can also benefit students beginning a computer science education. Computer science trainees can find free seminars like Intro to Front End Web Development, the Intro to Node.js seminar (appropriate for web development students), and Intro to SQL, a perfect choice for data science and Python programming students.
For additional tutorials, check out Noble Desktop’s YouTube channel, where you’ll find playlists like Front End Web Development and Python, Data Science & SQL.
