"Medical schools and many other health professions graduate programs require two academic years (including laboratory experience) - usually one year of inorganic chemistry and one year of organic chemistry. At University of Michigan, the Chemistry Department has set up the following 4-semester sequence: General Chemistry, Organic Chemistry (I), Organic Chemistry (II), Physical Chemistry. The starting point for students is determined by the results of the placement tests in chemistry and mathematics that are taken during orientation. To meet medical school requirements, students must take four terms of chemistry with lab."
This is taken from the UM pre-med advising page. So, apparently it goes Gen Chem, Orgo I, Orgo II, PChem.
