Khan Academy is for the people and by the people. This free educational platform is terrific for those looking to brush up on subjects like science, math, the humanities, and more, but if you want something a little more advanced, that's where the fun stops. Khan is limited by its free nature, but thankfully, there are plenty of other options out there for you to try. So, let's take a look at five of the best online education sites right now.

BEST ONLINE EDUCATION SITES LIKE KHAN ACADEMY: YOUTOKEN

Long, sleepless nights. More work than you can keep up with. A bald head from pulling out your hair in frustration. These are the things we usually associate with education. YouToken wants to change all of that, though. Even though it covers some complex material that will prepare you for success in the real world, the actual learning process is fun and even easy. It's not stuffy or tedious. It's the way learning really should be.

BEST ONLINE EDUCATION SITES LIKE KHAN ACADEMY: UDACITY

Data science is one of the sexiest jobs one can have nowadays. If you agree with that statement, then try out Udacity. This platform focuses mostly on technology but there are a handful of other courses as well. Furthermore, Udacity is not high-intensity. You learn at your own pace and decide how you want your career to look.

BEST ONLINE EDUCATION SITES LIKE KHAN ACADEMY: CODECADEMY

PHP, Ruby, and Python are different languages that baffle the minds of so many people out there, but it doesn't have to be that way. Learning these languages is made easy with the right instruction, and in this case, the instruction comes by way of Codecademy. Whether you are a fast learner or slow learner, Codecademy lets you learn at whatever pace you want. By the end of the course, you'll be building your own projects.

BEST ONLINE EDUCATION SITES LIKE KHAN ACADEMY: BLOC

Before you dive into Bloc, keep in mind that it is not cheap. Tuition starts at around $4,000. What do you get for it? Well, you get a highly intensive, quick learning experience that teaches you the ins and outs of Web development. If you want a career change, this is a great option.

BEST ONLINE EDUCATION SITES LIKE KHAN ACADEMY: IVERSITY

iVersity puts the "I" in "University." What does that actually mean? Well, it means you get to work with some top-rated European universities and some international ones as well. Also, it's free! Don't get too excited, though. iVersity doesn't give you any legitimate certification.
