Drew Barrymore: 11th Grade Drop-Out
Former child star and notorious free spirit, Drew Barrymore never finished high school, but she did do a lot of other stuff. She started acting at 11 months old (in a commercial), checked into rehab at 13, legally emancipated herself from her mom at 15, and dropped out of high school in 11th grade.
Through all that, she managed to completely rehabilitate her career after hitting rock bottom in her early teens. To say that Drew is a student of life is an understatement!
