if applejack, applebloom, and big mac all attend the same highschool how far apart are their ages? and If sunset shimmer was the princess of the dance three years runing it would suggest that she and Applejack are in their senior year. At which case, why is BigMac at the school? did he get held back? does he work at the school? Is it a case where BigMac and Applejack are a year (or less) apart and AppleJack started school early?
