School classes are not what my student selected

I don't know if it is just our school or all of them but this is the third (and final year, thank God) of selecting classes in June with the class advisor, have meetings and then when school starts none of the classes are what they selected or what they have going to is classes they have already completed! Then we need to spend the first week of school meeting AGAIN with the advisor to figure out the classes.

Note: about half of our students friends are having the same issue
