This is not the case with all state schools. Mine, for example, was contrary to that. Different colleges in the University had different tuition. Obviously Art, Theater, Music, and Engineering have different costs -- why should they all pay flat rates?

On top of that, majoring in something technical will also likely require more fees -- lab fees, computer fees, etc.

Oh, and your book costs will be higher. Textbook prices have tripled in the last ten years, so now an English Major is paying what I paid for Computer Engineering back in 2000.

Simon Fraser University (Canada) charges more for engineering and cs courses.

And you actually pay cheaper per hour, because full-time tuition is invariably flat rate, but STEM majors (especially engineering) tend to have higher than normal credit hours per semester.

UIUC charges more in tuition for students that are in technical majors.
