Chris Brown is ready to move on.

The singer, 21, wrapped up his court-mandated domestic violence classes on Monday -- and Tweeted about it.

"I'm done with class," Brown Tweeted, even posting a photo of his certificate. Back in August 2009, a judge ordered Brown to attend one year of classes -- plus six months of community labor and five years' probation -- all stemming from his February 2009 felony assault of then-girlfriend Rihanna.

"I have enough self respect and decency to be proud of accomplishing this DV class," Brown added Monday. "Boyz run from mistakes. Men learn from them!!!"

The star is also barred from communicating Rihanna, 22, for five years.
