NEW YORK (CBS/AP) – Congratulations seem to be in order for Chris Brown, who after assaulting his ex-girlfriend Rihanna has successfully completed a domestic-violence education program – and he posted the certificate to Twitter to prove it.

Brown, who must have felt he deserved a pat on the back for completing the 52 week course, posted his “Certificate of Completion” along with a message on Twitter Monday, reports E! Online.

“I’m done with class,” he wrote.

After his fall from grace for last year’s assault on pop star Rihanna, the controversial R&B singer has begun to redeem himself by garnering three Grammy nominations, as well as a glowing progress report from a Los Angeles Superior Court Judge, who applauded Brown for working diligently to complete the terms of his probation.

“Out of thousands of probationers, no one has done a better or more consistent job than you have,” Schnegg told Brown during a brief hearing Thursday. “I really want to commend you for taking responsibility and for actually working diligently to complete all the things the court has required of you.”

The “Forever” singer was sentenced last year to five years’ probation and six months of community labor after pleading guilty to felony assault. He was charged after attacking award-winning singer Rihanna in a rented sports car just moments after a 2009 pre-Grammy Awards party.
