Chris Brown is hoping to put his violent fight with Rihanna in the past with the completion of his 52-week court-ordered domestic violence course.

The 21-year-old singer posted his certificate of completion on Twitter. The paper reads, “This certificate is presented to Christopher Brown For Completion of the Fifty-Two Week Domestic Violence Course of Commonwealth Catholic Charities.”

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

Back in August of this year, Superior Court Judge Patricia Schnegg praised Brown's progress telling the singer, "You’re doing very well on probation. You’re doing a great job.”

Last year, Brown was sentenced to five years probation and six months of community labor stemming from his assault on Rihanna after a pre-Grammy Awards party in February 2009.
