IC alone will get you an A in Research Methods and Adulthood and Aging. I only scored a B on Gerontology and a C on Organizational Behavior (OB) using IC alone. I would recommend supplementing these two exams with another source, especially the OB exam. Remember, the IC OB material was designed for the Dantes LL version. It will get you a C but I can't imagine much better unless you have a lot of knowledge on the subject going in.
