There are several starting points in the department curriculum. Most students start in the calculus sequence, discrete math, linear algebra, statistics, or in a computer science course.

### CALCULUS

We have a three course calculus sequence that is different from AP Calculus and different from the traditional Calc I, II, III sequence found at most colleges and universities. In particular, all three of our courses use functions of multiple variables.

##### Where should I start in the calculus sequence?

**Math 135, Applied Multivariable Calculus** I: This course is appropriate for students with no calculus background; however, it is different from a traditional calculus 1 and may be an appropriate course for students with a calculus background who are interested in developing mathematical modeling skills. Course Description.

**Math 137, Applied Multivariable Calculus II**: This course is recommend for students who have had a successful year of high school calculus (as merely one example, AB calculus with a score of 4 or better on the AP exam). Course Description.

**Math 237, Applied Multivariable Calculus III**: Students who enter Macalester having taken BC Calculus with a score of 4 or higher on the AP exam are encouraged to start here. Course Description.

##### How far do I need to go in the calculus sequence?

Mathematics, Physics, and Chemistry majors need to complete the calculus sequence through Math 237. Economics and most Biology students need to complete any one of Math 135, Math 137, or Math 237. Biology majors with a Biochemistry emphasis need to compete Math 137. We encourage you to see the departmental web pages (Biology, Chemistry, Economics, Physics and Astronomy) for these other majors and speak with a member of the department to verify their mathematics requirements.

### OTHER STARTING POINTS IN MATHEMATICS

**Math 155: Introduction to Statistical Modeling** is our introductory statistics course. It is required for the Math major, the AMS major, the Statistics minor, and other majors on campus (including Biology and Economics). Math 155 is a course unique to Macalester, with an emphasis on multivariate modeling, and it cannot be replaced by AP Statistics credits. Course Description.

**Math 136: Discrete Mathematics** is a good starting point for students who are interested in mathematics and want to try out areas of mathematics that are different than calculus. This course is required for the mathematics major and the computer science major but not the applied mathematics and statistics major. Course Description.

**Math 236: Linear Algebra** is a good starting point for students who have already completed calculus at the level of Math 137. This course is required for the mathematics major and the applied mathematics and statistics major. Course Description.

### STARTING POINTS IN COMPUTER SCIENCE

**Comp 123: Core Concepts in Computer Science** is the most common introductory course in computer science. It is suitable for students with little or no background in computing, programming, or computer science. This course serves both as a first course in the major and minor as well as an introduction to computer science for those not planning to take further coursework. This course is offered every semester. Course Description.

**Comp 120: Computing and Society** is a first year seminar course that is offered most fall semesters. It replaces Comp 123 in the major and minor. Course Description.

**Comp 124: Object-Oriented Programming and Data Structures**: Students who have significant prior experience in computer science may choose to start in Comp 124 with permission of the instructor. Course Description.
