(3) Major School and Electives-at-large.
At least two years before the date of expected graduation the
candidate must select one of the schools of natural or mathematical
science as his Major, or principal, School; and during the remainder
of his candidacy must pursue work in that school. As subsidiary
to the principal subject thus chosen, he shall pursue such other
courses within the limits of the electives-at-large (see below) as
are deemed most important in his case by the professor or professors
in charge of his major school, and approved by the academic faculty.
Each elective-at-large consists of a B Course, or of a C Course of
which the precedent B Course has been completed. After five B
Courses have been chosen in accordance with Section (1), (b), of
these regulations, the six electives-at-large required are to be selected,
(subject to the restrictions detailed in the first paragraph of this
section), from the lists of B and C Courses described under the
head of the academic schools, pp. 116-155.
