The traditional way of attending a university in person has been how people studied for a degree for many years. Lately, however, even the most prestigious ivy-league colleges offer computer science classes online.

This means that anyone with an internet connection can study in this field and eventually even obtain a computer science degree, all online.

How Computer Science Classes Online Work

When you sign up for a computer science class that takes place over the internet, you’ll typically attend classes through video sessions.

Those video sessions are either via a live, scheduled class, or by watching recorded videos provided by the professor.

Many (but not all) of these classes also include exams and grades. Usually, the free classes are simply videos. But, if you’re working toward an online degree, you’ll usually have a syllabus and exams just like if you were taking the class in person.

The following Universities and Colleges offer computer classes on line. If you dream of working in the field of computer science, these are a great place to start.

The Best Computer Science Classes Online

The following courses are available from some of the top online course websites on the web.

There are plenty of free classes to try to see if Computer Science is the field for you. If you want to get a job in the field, you should consider investing in the paid classes instead.
