Massively online open courses have transformed learning. Thanks to MOOCs, pretty much anyone with an internet connection and a desire to learn can receive a vital education on almost any topic.

Of course, these online courses aren’t free. But Udemy is holding a Holiday Flash Sale that’ll get you pretty close. From now through Friday, December 29, 2017, Cult of Mac readers can access any course costing $200 or more for just $10.

That low price includes lifetime access to each course you choose. Additionally, the Udemy courses come with a 30-day money-back guarantee. This is a great opportunity for anyone looking to improve their resume or gain new skills and insights.

Upgrade your brain and your resume

Udemy is one of the titans of the MOOC landscape, with expert instructors in a wide variety of disciplines. The online teaching hub offers some 55,000 courses to more than 20 million students globally.

The course offerings run the gamut: You can quickly master new skills in design, photography, IT, marketing, music, education, health and fitness, and on and on.

Udemy is known in part for offering a unique platform where people can start and grow their own courses. So even if you aren’t burning to learn any one thing in particular, perusing Udemy’s homepage reveals topics you may never have imagined.

Did you know ethical hacking was a thing? Ever considered studying the art of persuasion? Want to catch up with the field of machine learning, or just basic web coding or game design? How about diving into a graphic design bootcamp?

Whether you can name a field of study or not, there’s a Udemy course or two (or maybe 200) that cover it.

Learn vital skills with $10 Udemy courses

This is a chance to learn in-demand skills, enrich your mind, or boost your resume for the price of a decent lunch. If that sounds enticing (and of course it does), head to the Udemy website before Friday, December 29, for lifetime access to hundreds of courses for just $10.
