Are you familiar with the WUE programs?
They allow students from the contiguous Western states to apply to participating schools,
and pay in-state tuition plus 50%, at many out of state schools.
Not all schools in all states participate, but if you’re really looking to get out of ND, then it’s worth a look.
To see which schools have the major that you’re looking for, click on the School Search: Find Your Major button in the right-side gutter.
While it may never be as cost-effective as your in-state options, many schools will gt you very close.
Good luck.
