As I understand it, the laptop fee isn't "included" in tuition fees. But it sounds like it is an associated fee (like access to the gyms is about a $300 fee that's automatically applied to the U-Bill).
The following statement from the Student Tablet Computer document on the admitted student page:
"After you are admitted to veterinary school, a charge for the cost of the computer will be placed on your University Bill for the Fall Semester. As an entering VM student, the cost of the computer has already been factored into the financial aid award offer which you received in May. If you have questions about the financial aid award, please contact the Office of Financial Aid."
So it is factored into the financial aid award, if that makes sense. To break it down, Spring semester in-state was $11,196 + Activity fee of $331.95 + Health facility fee of $8.00 + Health fee $120.00 + Technology fee of $130 = TOTAL VET MED RESIDENT TUITION FEES of $11,785,95.
The laptop will be an extra $2,550 in the fall semesters tuition, so fall will probably cost $14,335.95, IF tuition fees aren't changed. You can see what the activity fee, health facility fee, etc entails: registrar.iastate.edu/fees/othfee.
