In high school, I took a college credit combined anatomy/physiology course for two quarters, getting a B and B+. Years later, at the university I graduated from, I took an anatomy course one semester and a physiology course another semester, getting an A and a B. Can I list the newer grades as retake courses for the combined anatomy/physiology course even though the credits weren't awarded from the same institution? By doing so, it would bump my sGPA from 3.55 to 3.61 and my total GPA from 3.47 to 3.48. Any advice?
