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.
  Answer   In my experience, a student must have at least 60 semester hours prior to classification as a Junior, but this varies for each institution and major.For e â¦ xample, if you were in a Nursing progam, they may require you to complete additional requirements prior to becoming a Junior.Example: You must take an additional Science and Labm, giving you 64 credits rather than 60. I've seen this requirement be as high as 72 for specialized programs.he above is an approximate number of credits particular to each classification. It really depends on the college or university. Still, the number would be very close. Remember the above is based on a college or university that operates of a regular two semester academic year.
