That is a common question we answer at the Office of Admissions. There is a popular misconception about being 'pre-med' or 'pre-law'.
Pre-med is not a major, rather it is a track of study with a particular end goal in mind. That end goal is getting accepted into medical school after attaining a bachelor's degree. According to published medical school acceptance data, Biology is the most common undergraduate major of future doctors, however medical schools accept applicants from other disciplines at near equal rates as biology majors. Therefore you are generally free to pursue a wide array of majors as long as you fulfill medical school prerequisites such as biology, chemistry, physics and math before applying.
As for pre-law, The American Bar Association actually does not recommend any one undergraduate major. Just like medical students, future lawyers come from a wide degree of disciplines. Law schools often look for applicants that have taken challenge classes in their college curriculum, maintained a high GPA, and scored high on the Law School Admission Test.
At Adelphi there are several Joint Degree Programs for students who know they ultimately want to become doctors and lawyers. Joint Degree Programs provide students with a direct path to professional careers. Some programs even allow you to skip a year of college and achieve your goal in a shorter period of time. For example, Adelphi's Early Admission partnership with Lake Eric College of Osteopathic Medicine permits students to enter medical school after just 3 years of studying at Adelphi.
There is also a Pre-Professional Advising office located in the Nexus Building. This office is open to the entire study body and helps students apply to the professional school of their choice, whether it be medical, law, dental or veterinary.
