*Chris Brown wants everyone to know that he has completed his 52-week court ordered domestic violence course.

The singer, who took the class as part of his punishment for assaulting Rihanna, took a picture of his completion certificate and proudly posted it on Twitter.

“im done with class,” the 21-year-old tweeted along with a link to the above photo. He later added another post, reflecting on how he’s changed since being convicted of felony assault in Feb. 2009.  

“i have enough self respect and decency to be proud of accomplishing this DV class,” he tweeted. “Boyz run from mistakes. Men learn from them!!!”

Brown received the certificate early Monday (Dec. 20).  He’ll remain on probation until 2014.
