In AISD the rule is you have to have an average of 80 or higher no more than two tardies, no more than three excused absences, no unexcused absences, no OCS (On Campus Suspension), and you have to be a junior or senior. Sophmores can earn exemptions in their core classes (Math, Science, English, History) in the spring semester by completing this criteria plus passing their TAKS test. Sorry freshman none for you. . I only have to take my Algebra II exam.
