You must take both Calculus I and Calculus III. Calculus I must be completed before you take Intermediate Macro, and Calculus III must be completed before you take Intermediate Micro and Econometrics. Please note that you do not need to take Calculus II to fulfill your economics major requirements. Students who are placed in Calculus II or III (either because of their AP scores or previous class work) by the math department will be assumed to have completed Calculus I and will be allowed to enroll in Intermediate Macro.
