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.
It really depends on what number of credits distinguish between a full-time and part-time student. For example, at my university, you must be enrolled in 13 hours each semester to be considered a full-time student. Therefore, in order to be a sophomore you will have had to complete at least 26 course hours.
