Ask yourself - Would your DD skip the AP exam for that subject at the end of the year if there is a conflict with softball? Because the dates for those exams are inflexible. Same with the SATs - if there is a conflict, softball or the SATs? Sometimes you have to make choices. The teacher did not create the scheduling conflict, and if it's teacher going to softball coach or softball coach going to teacher, it should be the softball coach going to the teacher, as he/she is the one asking for the exception for their player.
