Please keep the following advice in mind:
 When choosing between a harder course and an easier
course, we suggest you try the harder course for a few
days. It is much easier to move from a harder course to an easier course than from an easier course to a harder course.
 If you are planning to take a Calculus course at any point during your time at Colby, we recommend that you take it during your first semester here.
Below you will find information on:
[Return to Information for New Students .]
Several departments
require one or more mathematics courses for fulfillment of their
departmental majors or minors. If you are interested in a particular
subject you should thoroughly read the section in the Colby Course
Catalogue that details the requirements for a major or a minor in that
subject. Below we reproduce some of the mathematics requirements for
majors in various subjects. Read the information below in tandem with
the course catalog, not as a substitute! Clicking on the name of the department opens that department's catalogue entry in a new window.
 Biology
Major requires Mathematics 102 or 121 or 161 or equivalent; one additional course chosen from 122, 162, 212, 253 or Computer Science 151 is also required.
 Chemistry.
Major requires one year of calculus. Any of the
following combinations will satisfy the mathematics requirements for
a Chemistry major: 121 and 122; 101, 102, and 122; 161 and 122; 161
and 162.
 Computer Science.
Major requires one course chosen
from Mathematics 212, 231, 253, or 274 (but many have prerequisites).
 Economics.
Major requires Mathematics 121 or 161 or equivalent. In addition, Mathematics 381/382 will fulfill the statistics requirement for the major. There is also a joint major in Mathematics and Economics (listed under Economics) that requires Mathematics 122 or 162, 253, 311, and an additional upperlevel elective course.
 Geology.
Specific requirements vary among the specialties, but most require the same mathematics courses as chemistry (see above).
 Physics.
Major requires four of the following courses: Mathematics 102, 121, or 161; 122 or 162; 253; 262; 311; Computer Science 151.
 Mathematics.
A year of calculus is required to begin.
Mathematics 274 and 253 generally follow calculus, with more
advanced courses coming later. Read more about the Mathematics majors and minor.
Any major requirement of Mathematics 121 is also satisfied by
taking Mathematics 101 and 102, Math 122, or Math 161.
Most firstyear mathematics courses satisfy the "Quantitative Reasoning" distribution
requirement. However, so do some courses in Philosophy, Computer
Science and elsewhere. These courses are indicated by a "Q" in the course
catalogue and can be searched for specifically using Curriculum Search on the Registrar's webpage.
 MA101. The Math 101/102 sequence is equivalent to Math 121. This
twocourse sequence is designed to serve the needs of calculus students who are
weak in algebra and trigonometry. The slower pace of Math 101/102
allows students to acquire or strengthen these necessary skills along with
the calculus and then move on to Math 122. It is expected that
all students who take Math 101 in the fall will also take Math 102 the
following January. Math 101 alone does not satisfy any major or college requirement.
 MA121. This is the beginning of the mainstream calculus
sequence. Its main goal is to lead students to a sufficient grasp of
the concepts of the calculus allied with computational
skills. Students continuing their study of mathematics normally
choose 122 after this course.
 MA122. This is the choice of students who have had a year
of calculus in high school, have done well, and are mainly interested
in the applications, rather than the intellectual foundations, of
calculus. This course presumes that students know the basics of
integration and differentiation and the fundamental transcendental
functions (sine, cosine, exponential, and logarithm). Students
continuing their study of mathematics normally choose 253, 274, or 262
after this course.
 MA161. This is the first course of the honors calculus sequence at Colby. It is a synthesized approach to the calculus of one and several variables presented as a deductive mathematical theory, with emphasis on concepts, theorems and their proofs. This is an ambitious choice and almost all students who enter this course have taken and done well in a full year of calculus in high school. Students continuing their study of mathematics normally choose Math 162 after this course. Many continuing students choose to take Math 253 or Math 274 in addition to Math 162 after this course.
 [SC110.] Not offered 20142015. An elementary statistics course designed for those who want an introduction to statistics, but do not need a more rigorous course for the sciences or economics. Satisfies the "Q" requirement.
 MA111. A liberal arts math course that examines both the nature of mathematics and the historical and contemporary role of mathematics in our culture. Satisfies the "Q" requirement.
 SC212. An elementary statistics course designed primarily for the sciences. This course is in high demand by upper class science majors who will constitute all of its population in the fall. Firstyear students will not be admitted in the fall and are instead encouraged to take Mathematics 101, 121, 122 or 161 and sign up for SC212 at a later time (usually as a sophomore).
 SC231. An elementary statistics and regression analysis course that requires knowledge of calculus. This class will likely not be offered in the future. Students should instead consider SC 212 or, if majoring in Economics, should consult with the Economics Department as to the approriate course to take and when it should be taken.
 MA253 or MA274. These are both very ambitious
choices that do make sense for some incoming students. However, MA 161 or MA 122 is the better choice for most students. If you are considering either MA253 or MA274, please come see us during the orientation period to talk about it.
