My son is from a rural high school in California who knew no one at Vanderbilt when he arrived on move-in day. 18 months later he can’t imagine going to college anywhere else. He has a great group of friends. Every student that arrives at Vandy brings something unique to the class.
As far as being prepared, on Move-in weekend Vanderbilt Leadership assured the parents that they were confident that all students at Vanderbilt could be successful. In fact, they said that 95% of the applicants could be successful.
Your background will not prevent you from being successful. You bring a unique perspective to the class of 2019. Congratulations!
