MasterClass Although MasterClass offers more than just creative courses, its well-chosen offerings are the ones that put A-list actors, writers, artists, musicians, and more in the teacher's seat. Most courses have around 20 lessons, and these courses are video-based, with practical advice and demonstrations mixed with straightforward lectures, workbooks and class discussions. The price is about $15 per month for unlimited access, but students have to sign up for one year at a time. EdX Real college courses, created and taught by real college instructors, are available in a wide range of fields and topics. The biggest selling point for EdX is that the majority of their courses are free — but there's a catch. If you're just taking the class for your own learning experience, the free version (版本) will probably work, but if you want to have formal verification (证明) for professional reasons, the “verified certificate” option costs about $49 per class. Udacity The programs of the platform focus on web development, programming, cloud computing and data science. Each program includes hands-on practice, real-world applications and examples, and real instructors and career coaches who can address your individual needs. It's about $399 monthly, or roughly $597 for students who buy the full four months at once. Pluralsight Designed with working professionals in mind, Pluralsight offers courses in subjects like software development, data science, information security and more. Regardless of how many classes you want to take, the price is the same — about $29 per month for a personal plan (you can enjoy a 15% discount for a complete year). 21. Which one would you choos
