<p>Pre-dental is not a major or minor, it is an advisory program which also describes the courses you need to get into dental school, which includes a number of chemistry and biology courses. The problem with your CS major, business minor and pre-dental is their unrelatedness, meaning what you take as a CS major does not meet any of the courses you need for a business minor or meet most of the chemistry and biology courses that you need to apply to dental school. The courses required to complete a CS major in engineering are a very large number and add a business minor and the biology and chemistry courses needed for dental school means you can easily end up with a 4 1/2 to 5 year rather than a 4 year program.</p>
