48:26 - i'm not sure why, but i didn't need to create another method for when the student is deleted.
here's what i did:
if(trigger.isAfter && trigger.isInsert){
StudentTriggerHandler.createStudent(trigger.new);
}
if(trigger.isAfter && trigger.isDelete){
StudentTriggerHandler.createStudent(trigger.old);
}
does that make sense?
