'Tis the season to be brainy. On May 23, Cody Simpson graduated at the top of his high school class in Atlanta, Georgia. Two days later, Emma Watson rocked a cap and gown as she completed her studies at Brown University.

“It’s what’s in here that’s going to get you the furthest, regardless of any kind of wealth or looks or material possessions or anything,” Simpson said as he pointed to his head during his valedictorian speech. “It’s always what’s in here that’s going to get you the furthest. Intelligence is the sexiest thing in the entire world.”

We tend to agree, which is why we've rounded up 11 more young stars you might not have known were super sexy brainiacs.

Miranda Cosgrove

Cosgrove was home-schooled during her "iCarly" years, but now the 21-year-old is studying film at the University of Southern California. Not too shabby.

Dakota Fanning

She doesn't live in the dorms, but Fanning is still very much a student at the Gallatin School of Individualized Study at New York University, along with...

Dylan and Cole Sprouse

Dylan might not be the brightest bulb when it comes to sharing sexy photos, but the former “The Suite Life of Zack & Cody” star began attending NYU with his twin brother -- focusing on video game design and humanities respectively -- back 2011. They reportedly received straight A's in Advanced Placement classes back in high school, so it's really no surprise that these child stars took a break to focus on the smart stuff.

Graham Phillips

Playing Julianna Margulies' ambitious young son on the hit CBS drama "The Good Wife" while studying for a degree at the nation's top university definitely can't be an easy feat, but Princeton student Phillips somehow makes it look easy. Alicia should be proud.

Elizabeth Olsen

Mary-Kate and Ashley very briefly attended NYU back in 2004, but it was little sis Elizabeth who actually graduated. The "Godzilla" star studied acting at the prestigious Tisch School of the Arts, earning her diploma in 2013.

Miles Teller

While we're on a Tisch kick, "Divergent" and "The Spectacular Now" star Teller earned a BFA from the Lee Strasberg Theatre & Film Institute before moving on to romance (and beat up) Shailene Woodley.

Troian Bellisario

Spencer Hastings is undoubtedly the brainiest "Pretty Little Liar," and the actress who plays her is one smart cookie as well. Bellisario earned a BFA in theater from the University of Southern California in 2009.

Holland Roden

The "Teen Wolf" star studied molecular biology and women's studies at the University of California, Los Angeles. Now that's impressive.

Alexander Ludwig

The up-and-coming "Hunger Games" star is currently attending USC, where he's also a member of a very exclusive fraternity. Take it easy on the jello shots, bro.

Jacqueline Emerson

Speaking of "Hunger Games" stars, Foxface is going to Stanford. She initially deferred in favor of fighting Jennifer Lawrence, then began taking classes in 2013.
