Jamie Lynn Spears passes her GED exam

Jamie Lynn Spears, the pregnant 16-year-old sister of pop wreck Britney Spears has passed her GED exam - and is thinking about college, a friend of the Spears family has revealed.

The 'Zoey 101' star - who revealed her shock pregnancy late last year, 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," the friend tells People magazine. "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, Jamie Lynn was snapped in Hammond, La., clutching a GED book close to her chest. She was accompanied by 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.
