The last thing your teen wants to do this summer is more homework…or is it? Summer school isn’t exactly the most fun thing ever, but specialized courses that offer a quick overview of an interesting topic might be. And, right now, Harvard University is offering free online courses for teens (and anyone else!) to take at their own pace from the comfort of their homes. This might just change the way your teen summers from now on!

Harvard has more than 100 self-paced, online courses that teens can enroll in this summer for free. (Did we mention it’s free? Summer camp could never.) The topics vary widely, from the generic to the incredibly specific. For example, they could sign up for the 11-week intro to computer science course, which covers broad computer science concepts, lessons on thinking algorithmically, and more. Or the Omens, Oracles & Prophecies class, which looks at different divination systems, from ancient Chinese bone burning to modern astrology.

There are also classes on persuasive writing and public speaking, Beethoven’s 9th Symphony, building resilience by learning to manage anxiety,  18th century opera, and managing happiness. The options vary as much as your teen’s interests do.

These self-paced classes take a few hours per week and are taught by real Harvard professors. They don’t count toward real college credit, but you can get a Harvard certificate for completed courses for an extra fee. If this is just something to help your teen pursue new passions, they can definitely just sign up for the free version, though.  (By the way, Harvard also offers online courses for anyone for a small fee, like intro to Tai Chi, which is $30.)

With high prices for summer camp and teens stressed about upcoming college applications, these free Harvard classes might be an interesting alternative solution that can help. At the very least, they allow you to explore a new topic risk-free.
