When I factor in summer costs and living expenses I come up with a number that is about 25% cheaper for wsu making it the cheapest school for a wa residents by far.
Some private schools are atleast double the cost
Ohsu is like 160% the cost and even if ur out of state currently wa is somewhat unique in that u can usually become a resident after ur first year which might make it the cheapest school in the nation
here's a little spreadsheet I just made based off of living in both places and tracking all of my costs religiously
