Many dental schools recommend taking upper division courses like histology, immunology, neuroscience, etc. For this reason, I have been considering taking one or more of aforementioned courses. However, I am wondering how helpful these upper division courses that I might take as an undergrad would be once I am in dental school. For example, would taking undergrad histology give me a notable advantage when I am taking dental school's histology? What are some recommendations you guys can make based on your experiences?
