The AD (aggregate demand) curve is defined by the ISâLM equilibrium income at different potential price levels. The downward sloping AD curve is derived from the IS/LM model.
Who is considered a junior in college? A full college schedule requires 15 credit hours per semester, 30 credits per scholastic year: thus a sophomore would have earned 60 credits and a student carrying credit hours in excess of 60 credit hours would be conisdered a junior in college. Mohamed Elhegery.
Thus, a student may take 70 hours at the community college, and all of these hours may transfer to the senior college, and all 70 hours may apply toward the degree, but the student still is required to take the 60 additional hours at the senior institution. Thus this student's program is effectively 130 hours.
