You should go talk to an advisor at the preprofessional office. It's odd that they only offer chem I, unless that one course is the equivalent to chem I and II at other schools? Or perhaps you're mistaken... for example at my school, there is Intro to chemistry class which is just one semester... and there are separate inorganic chem I and II classes. A lot of newcomers think that the intro to chem is the required inorganic chem class but it isn't. Anyway, you do need both inorganic chem I and II so go speak to an advisor asap~
