Good essay, Nick.

A couple of points:
- You made this essay about art/music vs. drug treatments, and that's okay, but the prompt also mentions invasive procedures. If the prompt is art/music vs. drug treatments/invasive procedures, then you should mention both.
- Well written and nicely organized.
- I like how you suggested ways to fix the argument.

I'd give this a 5 or 5.5

One last point: always use official prompts when writing practice essays. You can also download them for free from the mba.com site.
