Imagine if you are living two decades ago and wanted to learn any skills from outside your city. One of the biggest hurdles of that time was the access to the resources outstation. If you would have wanted to acquire any skills, you needed to travel all the way to that particular place to acquire it. Imagine people coming from undeveloped areas of the world to Europe for acquiring and learning new skills. It needs money, time and courage to travel so much to acquire the knowledge which was worth taking at that time but not anymore because of online education.
