Duke student life

Hey everyone. I am starting to look at colleges and I am considering Duke as an option. I just have a few questions I am still unsure about:

  1. Is the vibe at Duke ultra competitive? Or is it more of a collaboration between students?
  2. Do students revolve around Greek Life?
  3. Are students generally happy?
  4. Does course work overwhelm students?
  5. Do students have fun at Duke?
