Back in my day there were Basic, Regular, and Advanced (or sometimes called Honors), and AP classes.

My son just finished middle school. They wiped out Basic classes because no one wanted to teach them and no one wanted their kids in Basic. So they renamed the classes to Advanced and Honors (advanced now has all the Basic and Regular kids in it and was supposed to be a more rigorous Regular class). And Honors became what used to be Advanced. Then this school had for each grade level one class of gifted that moved from class to class together (rather than the other kids that had randomized schedules). They were also considered Honors but they were a special honors group.
