Thanks to technology, learners in every corner of the globe can now study nearly any subject online, often for free or next to free. But such bounty can sometimes be overwhelming. With so many offerings, which classes really benefit students the most?
Class Central aims to clear up some of the confusion by curating the 8,000 or so MOOCs (massive open online courses) currently available to students. They also put together an annual list of the 50 most highly rated classes in areas from technology to the humanities.
"Students rate the classes on a five-star scale similar to how they would a restaurant on Yelp. We sort the classes based on the Bayesian average of their rating, which factors in the number of ratings for the class," Class Central founder and CEO Dhawal Shah explained to Inc.com in an email.
If you want to study Python or poetry, the complete list is here. However, if you are specifically hoping to hone your business skills online, here are the top five business-related MOOCs recommended by the 30,000 students who have reviewed classes on Class Central. To get a certificate of completion and have your work graded, you may need to shell out a small fee of about $50. Otherwise the courses can be taken for free.
