Question about tuition

I am a current high school student about to graduate in the upcoming month. Before paying the initial deposit I would like to have more info on exactly how much attending the U would cost. I have looked online about tuition and it says it will be around $12,000 a year. Also how hard would it be to get the For Utah scholarship .

I have received the Flagship scholarship and I am just wondering about how much I will be paying per semester/year. I will not be needing to pay for housing either.

Also, side note I got admitted for Biology and have decided I want to change that to computer science how easy would it be to change my major?

Thank you for any information :)
