(Corvallis, OR)  --  Tuition at Oregon State University is going up.  Last Friday, the Board of Trustees approved an increase of four-point-six percent for undergraduate students.  OSU will increase student financial aid by nearly 10-million-dollars to more than 125-million dollars.  That's nearly three times what it was five years ago.  The university says the increases are driven by inflation from labor, goods and services, along with costs from increasing enrollment.
