Hi, Faith! Getting into your dream school is a tremendous accomplishment and something you should be very proud of. I think Samantha made a lot of great points in her answer so I'll just add a little bit more based on my experience. I did not get into my dream school. In fact, I didn't get into my top three college choices. As you can imagine, I was pretty devastated about it at the time. However, I ended up loving the school I attended. Your college experience is entirely what you make of it. If you go to your dream school but don't try to have new experiences, make new friends, and spend your tenure there worrying about the cost of your education, you're probably not going to have a very positive experience. There are a lot of reasonably priced schools out there that have strong accounting programs. Also, accounting firms do not exclusively hire from marquee schools known for their outstanding accounting programs. A lot of firms want to see more qualitative factors like your willingness to take constructive feedback, how well you work in a team, and your leadership potential. Obviously strong academic performance is important too, but the name of the school on your degree probably doesn't matter as much as it might seem.
I am certainly not trying to dissuade you from going to your dream school - I'm just offering an alternate point of view. If you do ultimately decide to go there, a lot of accounting firms offer tuition reimbursement programs that help their employees repay student loans. A simple google search can help spell out the specifics of these programs - I would definitely recommend doing a little research to get the full picture.
I hope this helps - good luck in your decision!
