State Universities use academic classes only. They use English, Math, History/Social Studies, Science and Language classes. They weight honors with 0.5 and AP/DE/IB with 1.0 (for grades C and above). The do not include any art, music, band, chorus, health, leadership, architecture, business, PE, dance, athletic or other classes. They will add AP classes such as Psychology. Some admissions departments will add AP Art/Music.
They use semester grades, not quarter grades. So each semester counts as half of the total grade for the class. Public schools in the state report all grades as semester grades, not final grades. So you have to total up the semester grades with half the weight.
