When it comes to online learning, Udemy is one of the top sources. It offers over 80,000 courses to more than 24 million students. Since its mission is to improve lives through learning, it features an extensive and multi-language library on a wide range of courses from business, entrepreneurship, programming, academics, arts to even health and fitness, music and games. However, Udemy courses are created by individuals; so, as long as you are a self-proclaimed expert, you can create and design your own Udemy course, promote it and earn student tuition charges. While none of the courses are university-accredited, they can largely improve your skills.

If you are on the other side of the table, i.e. interested in learning, then you would be pleased to know of the discounted rates. While the listing price of courses is usually in the hundreds, they often go on sale and range $19.99 to $39.99. So, if you have a course in mind that you would like to sign up for, just be patient and wait for the sale. (Psst! Just sign up for their mailer and they will notify you when a sale comes. There is more than one sale a month, so there is no need to panic).

Investopedia is one of the leading sources of financial content on the web. While it offers a plethora of content, from market news, retirement strategies and investing in education to insights from financial advisors, it also provides useful resources to prepare for your finance exams such as Certified Financial Analyst (CFA).

Also, its content is of a high standard and often cites scholarly works to back up its views. The only downside is that Investopedia only caters to an audience in the US market.
