10 free online classes from Harvard to learn something new

While a year’s tuition at Harvard University will set you back nearly $50,000 (and that’s before room, board, and fees tack on another $20K), there’s a much cheaper option that doesn’t involve braving Massachusetts winters, or having to be admitted to the prestigious university at all. All you need is an internet connection to take certain Harvard courses for free in the comfort of your own home, thanks to the university’s fabulous online learning portal. 

You have options. There are free courses as well as courses that are free to audit, which means you can take the course for free but there is a cost to upgrade for additional content and/or to receive a verified certificate from HarvardX. 

We’ve handpicked a selection of some of the best free Harvard courses currently available, from the study of Shakespeare to a class that will help you better understand urban life. Our varied selection is like a wish list of courses we’re hoping to find the time to take in the near future.
