Where do you live? Can you recommend good places around Newark? Or even ones with a 30 min commute?
There are a great deal of nice towns for you to live in outside of Newark, however you need to decide whether or not you will have a car. If you will, then there are many nice small towns to live in like Rutherford, Lyndhurst, Nutley is okay, and a bunch more. If not then you will need to take mass transit, Jersey City, Hoboken, Newark and some other towns that directly link to the train which is about 10 walking minutes from the campus. Let me know some of your criteria and I can give you some suggestions as to appropriate places to live.
By the way, I will be starting Rutgers Law in August part time, however I grew up within 20 minutes of Newark and have been communting to the business school over the last 3 years so I know the routine pretty well by now.
