The College of the University of Chicago grants Bachelor of Arts and Bachelor of Science degrees in 51 academic majors[138] and 33 minors.[139] The college's academics are divided into five divisions: the Biological Sciences Collegiate Division, the Physical Sciences Collegiate Division, the Social Sciences Collegiate Division, the Humanities Collegiate Division, and the New Collegiate Division.[140] The first four are sections within their corresponding graduate divisions, while the New Collegiate Division administers interdisciplinary majors and studies which do not fit in one of the other four divisions.[141] Undergraduate students are required to take a distribution of courses to satisfy the university's general education requirements, commonly known as the Core Curriculum.[142] In 2012–2013, the Core classes at Chicago were limited to 17 courses, and are generally led by a full-time professor (as opposed to a teaching assistant).[143] As of the 2013–2014 school year, 15 courses and demonstrated proficiency in a foreign language are required under the Core.[144] Undergraduate courses at the University of Chicago are known for their demanding standards, heavy workload and academic difficulty; according to Uni in the USA, "Among the academic cream of American universities – Harvard, Yale, Princeton, MIT, and the University of Chicago – it is UChicago that can most convincingly claim to provide the most rigorous, intense learning experience."
