I was searching through the course timetable for next year and noticed that a lot of the courses for Classics are not being offered. I am considering majoring in Classics and this seems like a problem if I can't take half the courses. Is there a reason for this or is this just the current statuses of the courses? Is it possible their statuses may change or are all the courses locked in already? Your responses will be greatly appreciated.

They will probably change what courses you need to take to major in Classics if they're removing a significant amount of courses to major in Classics at the moment.
