Special Permission Number

I got accepted into Rutgers Business School Newark as a transfer student is it possible for me to get a special permission number to get into some closed classes. If yes should I email the professor or should I go and meet the professor in person.?

Haven’t heard of anyone meeting professors to obtain SPNs, emailing usually does the trick.

I heard something new that no one can get SPN’s for the business school courses no matter what even if your a senior is that true .?

If it’s a RBS specific rule I wouldn’t know.
