Out of the spotlight after revealing her pregnancy, 16-year-old Jamie Lynn Spears is moving ahead with her life, passing her GED and thinking about college, a family friend tells PEOPLE.

The Zoey 101 star passed her high school equivalency exam about a month ago – scoring particularly well on reading comprehension – and is looking to take the ACT college entrance test, the friend says.

"She's already got her diploma," according to the friend. "She wants to take her ACT. She's not wasting any time. People don't know her. When she gets something in her head, she'll make it happen. Everybody is so supportive of her."

Last month, Britney's younger sister was photographed in Hammond, La., carrying a GED book. She was accompanied by her mom Lynne outside a building that houses both the Tangipahoa Parish School System Adult Education Center, which is a GED preparation site, and the Title I Parent Center, which teaches parents how to help their children develop learning skills.
