"In a brightly colored classroom in an otherwise dismal place, Stanley Durden studies intently at a desk.
Durden, 51, says he wants to gain what he missed outside San Quentin State Prison - an education.
'I won't learn anything by sitting in the cell or watching TV. I prefer to have school,' said Durden, who has served 10 years of a 25-to-life prison sentence for repeated burglary and robbery convictions. He wants to earn his GED."
