MADISON, Wis. -

A Monona teen might be the youngest to walk across the Kohl Center stage and receive her bachelor's degree from the University of Wisconsin-Madison.

Less than three weeks after her 16th birthday, Serra Crawford graduated on Sunday. Crawford said she just enjoys learning.

The UW-Madison registrar's office said Serra is the youngest graduate since 1978, the year records began to be searchable.

At age 4, Crawford was doing second-grade math. By age 6, she was into trigonometry and algebra. And, by 10, she was doing college-level work. Home schooling and e-learning courses put her on the fast track.

The Wisconsin State Journal said intelligence runs in the family. Her brother, Kyler, was 16 1/2 when he graduated from UW-Madison last year.
