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.
You must complete 30 hours to become a Sophomore, 60 for a Junior, and 90 to become a Senior. 120 to graduate. Probably not if you are only taking AP classes while in high school. I don't think you could accumulate enough credit hours for a second year status. In my state (Ohio) high school students can participate in a Post Secondary Education Option Program at local community colleges.
