normal tutors can have at maximum a block of four sessions on any give day without break. However, i found out today that i have five, while i only requested four. 我就去问我的老板是怎么回事，她说you are the only tutor out of all forty to fifty tutors who can work more than four sessions and still retain possitive quality in your session. so naturally i ask why is that. and she said that because i am suitably emotionally removed from the student’s work so that i don’t get burned after four sessions. most tutors are overly invested and fails to realize in the end, it is the student’s work and not the tutors.
