I mentored a young man from a so-so school district who got into a top LAC (student body similar to Vandy) with a 29 ACT. His dad is a janitor and his mom works in a Chinese restaurant. At first, he was worried because everyone was so much better prepared for the rigors of the school … but he worked hard, got tutoring when needed, and ended up with a full ride at an ivy for a 2nd bachelors. He did often feel like he was one of the “few,” and it was tough at times, but he wouldn’t trade his experience for anything. Plus, I believe Vandy has more lower-income students than the LAC had.
Vanderbilt does not admit students they don’t feel can make it, and they provide support as needed. Congratulations, and know that you belong there!
