I called AACOMAS today about retaking 200-level courses to replace 300-level Genetics, Microbiology, and Cell Physiology. She said as long as they are the same credit hours with same course descriptions (and like for like, eg. - for science majors vs. non-science majors, or algebra-based vs. calculus-based for Physics), I'm good to go. I also asked if Genetics with a lab (4 cr), can be replaced with one without a lab (4 cr), she said fine with that too. A 2 minute phone call could change your life.
