I want to go to a 4-year university but my school couldn't get me the foreign language credits

I don’t know where you are getting $8912 in fees for Idaho State. This is the chart for 24-25 school year:

Expense Idaho Residents Non-Residents WUE* NRTW+
Tuition $8,914 $28,240 $12,037 $8,914
Room1 $3,300 $3,300 $3,300 $3,300
Meal Plan2 $4,036 $4,036 $4,036 $4,036
Books & supplies $1,000 $1,000 $1,000 $1,000
Total Estimated Costs $17,250 $36,576 $20,373 $17,250

The WUE tuition would be $12,037 (a little more now) and total COA of $20, 373. They also have something called "non-resident tuition waiver’ but not sure how one qualifies for that (sometimes it’s military service of a parent)

Wyoming would also be a good value for you. Its WUE scholarship (available to all, not just WUE state residents) is called the Brown and Gold scholarship, and engineers get additional scholarships too. Foreign language is NOT required to get accepted, but college of Engineering may require it to graduate.
