It’s been years since Ja Rule made some music, but the New Yorker has been sharpening his intelligence and keeping himself busy. The Pain is Love star, born Jeffrey Atkins, recently revealed he’s completed the Harvard Business School Online certificate program.

Ja first announced he would start classes in September over the summer. On Tuesday (Feb. 2), after concluding the program, he took to Twitter to express his excitement, writing, “I ain’t the sharpest knife in the drawer buuuuut,” alongside a screenshot of his certificate.

According to the post, the business courses were meant to provide students with a framework “to evaluate opportunities, manage start-ups and finance ventures” — skills that will help the Murder Inc. emcee as he runs Iconn, his new celebrity booking app developed with Fyre Media, the company behind the infamous Fyre Festival disaster.

The Ivy League knowledge has also given Ja Rule the confidence to drop words of wisdom to Twitter followers, including his recent rant about the GameStop and Robinhood controversy.

As REVOLT previously reported, the “Livin’ It Up” star made headlines and became a trending topic after he criticized the stock-trading platform for their decision to restrict certain GameStop stock trades. “Yo this is a fucking CRIME what [Robinhood] is doing DO NOT SELL!!! HOLD THE LINE… WTF,” he previously tweeted.

“The big Wall Street guys have been shorting these stocks. These guys decided to make the stock go through the roof, which in turn makes the big whales that shorted the stock now have to buy it,” Ja Rule later explained to Rolling Stone. “…That helped the little guy make a lot of money and I thought that was very interesting. It was an uprising of people tired of getting pushed around.”

“People are mad. People are angry and they should be,” he added during an interview with CNBC’s “Squawk Alley.” “This is the app that claims it is about free trade, and they took that power away from people.”
