In the 1990's, as a PhD candidate at Seoul National University and a degree holder from a top science high school, he was a prime recruit for the cram schools in Daechi-dong, Seoul's most notorious cram school ghetto. He started tutoring middle school students in science a couple days a week and then moved on to preparing high school students for the college entrance exam. He became a star in the test prep industry, tutoring every night and all weekend, reaching thousands of students.
"My income was so huge," he said in an interview. "For five consecutive years, I made more than one million dollars."

Megastudy and downloaded lessons in 2009
He and his wife -- another Daechi-dong tutor -- bought a four-bedroom house with a yard, a rare luxury in this city of skyscrapers, and they started a family.
Over time, though, the shine of his cram school fame tarnished. "I began to hate my job," he said. The tutors he worked with vied intensely for students, and he recalled that some colleagues paid people to write nasty comments about his classes. And as he got closer to some students, he saw how stressed out they were. "I realized the education system was ruining a lot of students - not just low performers but high performers, too."
He quit his job in 2003. A year later, Megastudy went public and he made more than $15 million, he said.
