 There are over 4,000 universities, as you said, and universities and colleges in the U.S. How do the costs vary from school to school? Okay, well, of course I can't go through all 4,000, but what I can say is, as I mentioned earlier, there are universities that are state, public universities, and colleges, including two-year colleges and four-year colleges. And there are universities, four-year universities, that are private and state supported. Community college is a great way to think of as a strategy for funding education. And many community colleges have articulation agreements. That means if a student has successfully completed the first two years of general liberal arts study in a community college, that school has an agreement with a sister four-year school for them to continue on and complete at the four-year school from the same chain of universities. So community college is a great way to start and make it more affordable. The tuition will usually be much less. The possible downside is that not every community college, actually the majority, do not offer housing. So the student would have to look for off-campus housing. But when they do the bottom-line math, it can still come out to be much more affordable to start and then transition to a four-year university, whether public or private. So the range will vary greatly overall. All those costs that I mentioned earlier anyway are from $30,000 to $60,000 a year, but there's such a variation in between there as well. And of course, community colleges would be much less. On the lower end.
