There are plenty of classes to choose from at Harvard; they offer almost 3,900 courses in 49 undergraduate fields. Your curriculum is designed based on your goals and they require no predetermined courses for your major outside of an Expository Writing course for all freshmen. Harvard also offers the opportunity for you to create a unique, personalized field that aims for your academic and career goals. The most popular majors overall in Harvard are Political Science and Government, Economics, Social Sciences, Evolutionary Biology, and Psychology. Both men and women tend to lean towards those fields of study, but a majority of men are found in Physics, Math, Computer Science, Natural Sciences, and Statistics. Meanwhile, more women are found in Anthropology, Women's Studies, German Language and Literature, Art History, Crit, and Conservation, and English Language and Literature. A majority of seminars have less than 10 students, giving you an excellent chance to develop a close connection with professors. Half of Harvard students also choose an honors track, requiring theses or research projects for their senior year. This includes one-on-one supervision by professors and tutors.
