ACM covers most of the southeast including Alabama, Arkansas, Delaware, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, Oklahoma, South Carolina, Tennessee, Texas, Virginia and West Virginia. Simply excludes North Carolina in Southeast. It applies if you are wanting to study a degree program that your states does not offer in any public university that is offered at another public university. You apply for instate tuition and keep it as long as you keep grades up and don't change majors. Most are not aware of it and high schools do not do a good job of telling people about it. You can even start in one major and take required classes and if you change majors there is no penalty you just have to pay out of state after you change majors. All classes taken must apply to within major as long as you are getting it.
