Passage: Kieślowski was born in Warsaw, Poland, the son of Barbara (née Szonert) and Roman Kieślowski. He grew up in several small towns, moving wherever his engineer father, a tuberculosis patient, could find treatment. He was raised Roman Catholic and retained what he called a "personal and private" relationship with God. At sixteen, he attended a firefighters' training school, but dropped out after three months. Without any career goals, he then entered the College for Theatre Technicians in Warsaw in 1957 because it was run by a relative. He wanted to become a theatre director, but lacked the required bachelor's degree for the theatre department, so he chose to study film as an intermediate step.

Question: How long did it take him to drop out of training school?
three months
