If you're going to be attending a university you may have questions about health insurance for students. Some schools will require that you have medical coverage in order to enroll in classes. Some schools will actually provide health insurance for students at a reasonable cost. Most colleges and universities will at least have a health care clinic available for students where they could receive treatment for minor issues.
Having health insurance is important because people with medical coverage receive better care and receive that care in a more timely fashion than people that are uninsured. It's also important to have because although young people in their late teens and early 20s are generally healthy, schools are places where illnesses and viruses can spread quickly and if you needed prescription medication to treat an illness the costs could add up very quickly. Also if you were to suffer some type of injury you would certainly want to be able to have a doctor treat that injury without racking up massive medical bills.
If your school provides health insurance for students you may still want to get a few quotes from other companies to see if the plan provided by your school is going to be the best coverage at the best price. It's possible that your school would not be offering the best possible plan and that you may be able to get a better deal somewhere else. It just takes a couple of minutes online to get multiple quotes from a number of different providers and then you can quickly and easily determine which plan would be the best bargain
