For six months, CBS News has followed a group of high school dropouts who received a second chance through a boot camp run by the National Guard.

Michael Scott, the First Sergeant of a National Guard boot camp for troubled teens, is in charge of the 28 sergeants who've made it their life's mission to turn at-risk students' lives around.

Troubled teens who used to see F’s and D’s on their report cards are now proudly boasting A’s and B’s.

Second Chances are what the Sunburst Youth Challenge Academy program is all about. Sponsored by the California National Guard and the State of California, the Youth Challenge facility has graduated more than 2,000 teenagers since 1998 and more than 1,700 have earned their GED or a high school diploma after attending this 22-week residential program. The National HS graduation rate is 78% while it is 72.5% in California. If you know of teenager that could use a second chance to turn their life around - please tell them about this program.
