Biology is a cornerstone of a medical education, and most U.S. medical schools require at least eight hours of biology classes, along with laboratory work. While this requirement can usually be filled with introductory biology I and II, some schools recommend taking genetics and embryology classes as well. Many pre-med students choose biology as their major or minor to better their chances of getting into medical school.
Chemistry is another important facet of medical training and is known as one of the early roadblocks on the road to becoming a doctor. Medical school applicants must have completed eight hours of general chemistry and another eight hours of organic or biochemistry. All of these classes must have a laboratory component. This sequence of courses takes two years to complete for most students, so it is important to plan your schedule ahead of time.
Students must take eight hours of physics classes with labs to complete the science curriculum for pre-med students. Students should also take at least six hours of English classes, although this requirement will most likely be necessary for the completion of any undergraduate degree. Math requirements vary depending upon school, but in general, it is wise to take at least six hours of college-level calculus.
Requirements and recommended undergraduate coursework vary greatly from school to school, so it is important for pre-med students to verify the admission policies of the medical schools they are interested in applying to. It is also important to note the policies regarding advance placement credits, if a student is hoping to substitute these credits for any required coursework. Most schools require a grade of "C" or better in all required undergraduate classes.
