Please keep the following advice in mind:
 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.
 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.

Mathematics and Statistics course requirements by major.
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.
Any major requirement of Mathematics 121 is also satisfied by taking
Math 122 or Math 161.
 Biology.
Basic Major requires Mathematics 121 or 161 or equivalent; one additional course chosen from 122, 162, 253, SC 212, or Computer Science 151 or 152 is also required. Certain specialized majors have different requirements; see Biology in the course catalogue.
 Chemistry.
Major requires calculus through 122 or 162. Any of the following combinations will satisfy the mathematics requirements for a Chemistry major: 121 and 122; 161 and 122; 161 and 162.
 Computer Science.
Major requires 200level mathematics or statistics course (but some CS courses have other Math prerequisites).
 Economics.
Basic major requires Mathematics 121 or 161 or equivalent. In addition, MA 381/SC 382 will fulfill the requirement for EC 293. See Economics in the course catalogue for details about options for upperlevel courses, as well as additional mathematics and statistics course requirements and recommendations, including those toward graduate school in Economics.
 Geology.
Major requires MA 122 or SC 212
 Physics.
Major requires four of the following courses: Mathematics 121 or 161; 122 or 162; 253; 262; 311; Computer Science 151 or 152. See Physics in the course catalogue about additional electives, as well as further mathematics course recommendations toward graduate school in physics and astronomy.
 Environmental Studies
The majors in this department require a combination of SC 212, MA 121 and MA 122, depending on the major. See Environmental Studies in the course catalogue
 Mathematics and Statistics.
Calculus thru 122 or 162 is required to begin. Mathematics 253 and 274 generally follow calculus, with more advanced courses coming later. Read more about the Mathematics and Statistics majors and minors. Read more about the Mathematics and Statistics majors and minors.
The Quantitative Reasoning (Q) requirement.
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.
Calculus courses at Colby
 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.
Statistics and other noncalculus courses
 [SC110] Not offered 201819. 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] Not offered 201819. 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 introductory statistics and data science course. Firstyear students will not be admitted in the fall and are instead encouraged to take Mathematics 121, 122 or 161 and sign up for SC212 at a later time (usually as a sophomore).
 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.
