I am currently a college freshman and I want to be a dentist. I am planning on doing the untraditional route and major in psychology and minor in art. I know there are prerequisite classes I must take and I made a 4-year plan to accommodate them all. However, are there any more classes I must take, such as microbiology, genetics, comparative vertebrate anatomy, multivariable calculus? I saw some schools recommended these classes. The problem is I don't think I have time to take these classes and I'm not interested in majoring in biology. Will I be at a disadvantage when I apply to dental school if I don't do many biology courses?
