A major sequence is a total of three-quarters of a year of successful full-time higher education study, usually comprising sequential discipline study taken over three years, e.g. a part in each of the first, second and third years of study, or equivalent study. In most tertiary, undergraduate degrees, this equates to six subjects, with no more than two at first-year level and no less than two subjects at third-year level.
