Does the phrase "leave school" mean "graduate from schools" or "drop out of school" to some extent? Someone told me her English teacher said that the "leave school" represents graduate from school (with completing all the required courses); however, the explanation from wiki says: Dropping out means leaving a school, college, university or group for practical reasons, necessities, or disillusionment with the system from which the individual in question leaves. Now I am a little bit uncertain about the exact meaning of the leaving school and if possible, could you guys explain that according to your knowledge?
