. It is known for its broad range of study in the first year, in which students cannot study just one discipline, but instead must choose three courses in different areas of the natural sciences and one in mathematics. As is traditional at Cambridge, the degree awarded after Part II (three years of study) is a Bachelor of Arts (BA). A Master of Natural Sciences degree (MSci) is available to those who take the optional Part III (one further year). It was started in the 19th Century.

Teaching

Teaching is carried out by 16 different departments. Subjects offered in Part IA in 2019 are Biology of Cells, Chemistry, Computer Science, Evolution and Behaviour, Earth Sciences, Materials Science, Mathematics, Physics, Physiology of Organisms and Mathematical Biology; students must take three experimental subjects and one mathematics course. There are three options for the compulsory mathematics element in IA: "Mathematics A", "Mathematics B" and "Mathematical Biology". From 2020 Computer Science will no longer be an option in the natural sciences course. Students specialize further in the second year (Part IB) of their

Motivation

The University of Cambridge believes that their course's generalisation, rather than specialisation, gives their students an advantage. First, it allows students to experience subjects at university level before specialising. Second, many modern sciences exist at the boundaries of traditional disciplines, for example, applying methods from a different discipline. Third, this structure allows other scientific subjects, such as Mathematics (traditionally a very strong subject at Cambridge), Medicine and the

has been completed, one can specialise in another biological science in Part II during one's third year, and still come out with a science degree specialised enough to move into postgraduate studies, such as a PhD.

Student enrolment

As a result of this structure, the Natural Sciences Tripos has by far the greatest number of students of any Tripos. Undergraduates who are reading for the NST in order to gain their degrees are colloquially known in University slang as NatSci''s (pronounced "Nat-Ski's"), being broadly nicknamed

('bio') NatScis, according to their course choices. (Of course, many students choose both physical and biological options in first year.) The split tends to be about 50:50 between the physical and biological sciences. In 2018, 2594 students applied and 577 were admitted to the Natural Sciences Tripos. In order to be accepted to study on the Natural Sciences course, students must sit the NSAA (Natural Science Admissions Assessment) exam in the year of their application. This is a test required by Cambridge to assess their candidates.
