Bristol Palin graduated from high school yesterday, a feat her mother doubted could be achieved when she became pregnant, People reports. “Oh, there goes her education,” Sarah Palin recalled thinking. Bristol, though, was confident. “I knew it would be hard work,” she said, “but I knew I was going to do it.” Her 5-month-old son attended the ceremony. Her only regret? Being “point zero-zero-something” away from graduating with honors.
