Updated Saturday with video and photos from the graduation.

The youngest student ever to attend TCU threw on a pint-sized graduation robe Saturday and walked across the stage to get his physics diploma.

Since enrolling in 2013 at Texas Christian University, 14-year-old Carson Huey-You also double minored in math and Chinese, Noelle Walker of KXAS-TV (NBC5) reports.

"It didn't come easily. It really didn't," he told the station. "I knew I wanted to do physics when I was in high school, but then quantum physics was the one that stood out to me, because it was abstract. You can't actually see what's going on, so you have to sort of rely on the mathematics to work everything out."

Carson will begin graduate school at TCU in the fall.

Physics professor Magnus Rittby told The Dallas Morning News last year that sometimes he forgets Carson's so young because he's so advanced.

"It's funny because sometimes he's very playful, and we do a lot of weird crawling on the ground to do our physics experiments," Rittby said. "And then other times, he's dead serious and sees me like, 'Oooo! The ol' physics professor.'"

Carson's mother, Claretta Kimp, told NBC5 that math first caught his attention at 3 years old.

"He asked me if he could learn calculus and I thought, "Hmm,'" Kimp said. "Everybody thinks I have a magic pill or something, but this is the norm for me."

People are particularly interested given that Carson's younger brother, Cannan, also hits the books — ones that are way beyond the normal reading level for an 11-year-old.

Cannan, who starts his undergraduate studies at TCU in the fall, told NBC5 that he plans to major in astrophysics and engineering.

Although the two put many to shame in the classroom, they also enjoy their time off campus. Carson loves music and Cannan makes stop-motion videos with Legos.

They've also connected with people from many walks of life.

"I have friends from high school and church and just people I've met along the way," Carson said. "They are people older than me, younger and some my own age. It's just a balance."

Kimp agrees. The divorced mom said she doesn't have a secret to success, but parents should realize that each child is unique.

"Allow your kids to fly in the direction they want to fly in and go at their own pace," she said. "But it's not just about schooling. You have to know your child and make sure they are healthy — physically, emotionally and spiritually. If you know they are OK, then they will just take off."
