West Texas A&M is not that far from Oklahoma (near Amarillo), has dirt cheap out of state tuition, and appears to still be taking applications.

Please do not pay much attention to “acceptance” rates. These can be very misleading. It all depends on who is applying. At WTAMU, your ACT score would put you in roughly the top ten percent. Its 71% acceptance rate is irrelevant to you.
Also, the University of Central Oklahoma is on one list of colleges with rolling admissions. You might want to check it out.
