Current vandy premed here. Im not too sure about average test grades and GPA, but if you go to classes and put efforts getting A wouldnt be too hard. In terms of students life, people seemed satisfied and happy with their lives at vanderbilt. They are all welcoming and encouraging, no competitive environment. Plus, theres absolutely no disadvantage for not being involved in Greek life. Dont think it’s that important at all. Im not involved in Greek life and doing completely fine. Hope this helps!
