I live in Chicago and work at a building on the Rush campus. Are you planning on taking transit? I used to live around Wrigley, and that neighborhood as well as Lincoln Park are both tremendously safe. Rush is in a generally safe area, but it's definitely a lot closer to "bad" areas than neighborhoods on the North Side like LP or Wrigley. The only downside about living in those neighborhoods transportation wise would be that you'd have to transfer between trains so your commute would be a bit longer. Regarding safety, you should be fine so long as you're not leaving school past 9 or 10. There's safety in numbers, so it's always best to travel at times when there are going to be other people on the train/bus with you. If you've gotta leave super late, than you can always take a cab.
