If you want to go out of state, than it is your job to figure out how to pay for it. Your sister did that by earning the scholarships. UPENN Wharton school of business is a fabulous school. You are right in saying that your sister did well for herself by earning the scholarships to go there. She wanted to attend an out of state school and found a way to pay for it that your parents could agree with so she could get what she wanted.
www.fastweb.com is a search engine for scholarships. You can begin earning scholarships to pay for college in middle school. You can also contact the school, WVU, directly and see what scholarships they have that are available for someone like you.
My daughters were required to submit their applications before November 1st so that the could use their college entrance exam scores to assist them with tuition scholarships. Did you do that? They also had to apply to scholarships directly through the universities of their choice and through fastweb. I encouraged them to apply to at least one scholarship a week. They knew that our ability to fund their schooling was limited. They also knew that depending on school loans to cover the majority of the cost of their schooling would be poor planning for the long term. One should never incur extra debt if it can be avoided.
Hopefully, you are not currently a senior...because you may have backed yourself into a corner by failing to answer the question of how the school is going to be paid for if you choose to attend an out of state school by putting the question off until it was too late to come with an answer that will make you and your parents happy.
Remember that when one is choosing a school out of state that the fees involved for schooling can triple. One has to consider tuition, housing, books, school fees, transportation to and from school, parking fees if a car goes with you, etc. Students are considered unemancipated minors until the age of 21 by most universities residency determination policies.
Good Luck!
