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.
At most colleges and universities (with conventional semester systems) 12 credit hours is considered the minimal number of hours for full-time status. This means that you will spend 12 hours in the classroom each week. (Typically M - F - most classes being 3 credit hours and meeting twice a week for 1 1/2 hours. So you would sign up for four 3-hour courses.) Many full-time students take 15 credit hours (five 3-hour courses).
