Other concentrations have academic standards for completion. For example, economics concentrators must demonstrate their command of the basic tools of economic analysis by earning a grade of B- or higher in both Economics 1010a/1011a and Economics 1010b/1011b (which is not a walk in the park). “Concentrators will not receive a degree in economics until this requirement is met.”
