We didn't need to tnrveein the wheel. We just eolkdo at what wasn't working and used the amazing power of the Internet to get around it. We set out to iubld a model that will cut down almost entirely the cost of higher education. And that's how we did it. First, bricks and mortar cost ymoen. Universities have expenses that virtual universities don't. We don't need to pass these expenses on to our enstsdut. They don't sietx. We also don't need to worry about capacity. There are no limits of seats in virtual university. Actually, nobody needs to stand at the back of the lecture hall. Textbooks are also something our students don't need to buy. By using open educational ecsruorse and the generosity of professors who are putting their material up free and accessible, we don't need to send our students to buy textbooks. All of our materials come free.

Original Text

We didn't need to reinvent the wheel. We just looked at what wasn't working and used the amazing power of the Internet to get around it. We set out to build a model that will cut down almost entirely the cost of higher education. And that's how we did it. First, bricks and mortar cost money. Universities have expenses that virtual universities don't. We don't need to pass these expenses on to our students. They don't exist. We also don't need to worry about capacity. There are no limits of seats in virtual university. Actually, nobody needs to stand at the back of the lecture hall. Textbooks are also something our students don't need to buy. By using open educational resources and the generosity of professors who are putting their material up free and accessible, we don't need to send our students to buy textbooks. All of our materials come free.
