I have taken many courses at Coursera over the last 15+ years and it’s a great way to try something new. Occasionally, the topic isn’t what I thought, and I didn’t finish the course. That’s the flexibility I appreciate. Coursera has so many options not only for free courses but they have degree programs as well.
We collaborate with 325+ leading universities and companies

I’ve taken some free coursera courses too. They are excellent!
I would think a large part of the world truly love to take courses to expand their knowledge or more important their self confidence. 🙂
