I was accepted to ASU but decided to attend Embry Riddle instead. I'm studying aerospace engineering.
It sounds like you are unsure of what you want to do. If that is the case, then attending a school like ASU may be a good idea. They offer a wide range of programs and you have the option of trying them out until you find one you like. Jumping right into one of the "premium" schools like Harvard may seem like the best idea, but it's a risky and expensive way to go if you aren't sure about what you actually want to do with your life. When you finally do decide on a career path, you will stand a better chance at getting into some of those "premium" colleges by being a transfer student.
