single word requests - What adjective describes somebody who is quiet and obeys all the rules?



What adjective describes somebody who is quiet and obeys all the rules? For example,


"Xiaoli is a very (adj.) student because she doesn't smoke or drink, gets good grades, and always does her homework ahead of time".


The word that comes to mind is obedient, but I think this word has the negative connotation in the way that a servant would "obey" his master. I'm looking for an entirely positive adjective.


A possible antonym to my word might be wild, which you might use to describe someone who parties all night, gets drunk, etc.
