Courses offered by Mathematical and Computational Science program are listed under the subject code MCS on the Stanford Bulletin's ExploreCourses website.
This interdisciplinary undergraduate degree program in MCS is sponsored by Stanford's departments of Statistics, Mathematics, Computer Science, and Management Science & Engineering, providing students with a core of mathematics basic to all the mathematical sciences and an introduction to concepts and techniques of computation, optimal decision making, probabilistic modeling, and statistical inference.
Utilizing the faculty and courses of the departments listed above, this major prepares students for graduate study or employment in the mathematical and computational sciences or in those areas of applied mathematics which center around the use of computers and are concerned with the problems of the social and management sciences. A biology option is offered for students interested in applications of mathematics, statistics, and computer science to the biological sciences (bioinformatics, computational biology, statistical genetics, neurosciences); and in a similar spirit, an engineering and statistics option.
Undergraduate Mission Statement for Mathematical and Computational Science
The mission of the Mathematical and Computational Science Program is to provide students with a core of mathematics basic to all the mathematical sciences and an introduction to concepts and techniques of computation, optimal decision making, probabilistic modeling and statistical inference. The program is interdisciplinary in its focus, and students are required to complete course work in mathematics, computer science, statistics, and management science and engineering. A computational biology track is available for students interested in biomedical applications. The program prepares students for careers in academic, financial and government settings as well as for study in graduate or professional schools.
Learning Outcomes
The program expects undergraduate majors to be able to demonstrate the following learning outcomes. These learning outcomes are used in evaluating students and the department's undergraduate program. Students are expected to be able to demonstrate:
 understanding of principles and tools of statistics.
 command of optimization and its applications and the ability to analyze and interpret problems from various disciplines.
 an understanding of computer applications emphasizing modern software engineering principles.
 an understanding of multivariate calculus, linear algebra, and algebraic and geometric proofs.
Bachelor of Science in Mathematical and Computational Science
The Program in Mathematical and Computational Science (MCS) offers a Bachelor of Science in Mathematical and Computational Science. Eligible students may also pursue a Bachelor of Science with Honors. The department also offers a minor in Mathematical and Computational Science.
Suggested Preparation for the Major
Students ordinarily would have taken two of the required Math courses (MATH 51 Linear Algebra, Multivariable Calculus, and Modern Applications/MATH 52 Integral Calculus of Several Variables/MATH 53 Ordinary Differential Equations with Linear Algebra) and one of the required Statistics core courses (STATS 116 Theory of Probability, STATS 191 Introduction to Applied Statistics) before declaring MCS during their freshman or sophomore year.
How to Declare the Major
To declare the major, a student should first meet with an MCS peer advisor to create a proposed study plan and then with the MCS student services officer to discuss the major. Students ordinarily have taken two of the required MATH 50 series courses and a core Statistics course prior to declaration. Once the student has created a proposed study plan, they should connect with the MCS student services officer and declare the major through Axess. Students should have an overall grade point average (GPA) of 3.0 to declare.
Degree Requirements
 The student must have a grade point average (GPA) of 3.0 or better in all course work used to fulfill the major requirement.

At least three quarters before graduation, majors must file with their advisor a plan for completing degree requirements.

All courses used to fulfill major requirements must be taken for a letter grade with the exception of courses offered satisfactory/no credit only.

Students who earn less than a 'C+' in STATS 116 Theory of Probability or STATS 200 Introduction to Statistical Inference must repeat the course.

Only one MCS core course can be substituted by filing a petition with their advisor (with the exception of STATS 200 Introduction to Statistical Inference which cannot be substituted). The Course Substitution Form must be submitted the quarter prior to enrolling in the course.

Course transfer credit is subject to department evaluation and to the Office of the Registrar's external credit evaluation. These courses may result in a replacement course for MCS required course or may establish placement in a higherlevel course. Transfer requests must first be submitted to Student Services Center prior to being evaluated by your advisor. Submit the MCS Program Transfer Credit Form to the student services office.

Students may take their three electives courses for credit (CR).

Students may be granted a onetime exception to take a core course for credit (CR) with the exception of STATS 116 and STATS 200.

The University requires students to complete at least one approved writingintensive course in each of their majors. See the Hume Center for Writing and Speaking web site for a full description of the WIM requirement.

Honors Program
The honors program is designed to encourage a more intensive study of mathematical sciences than the B.S. program. Students interested in honors should consult with their faculty advisor as soon as possible to allow more opportunities in course planning and concentration area. The honors program allows for a capstone experience, building upon the student’s current academic knowledge and strengthening their understanding in a specific field of study/concentration. Honors work may be concentrated in fields such as biological sciences and medicine, environment, physics, sports analytics, investment science, AI/machine learning, etc.
Students are required to submit an MCS Honors Proposal Form describing the concentration for honors work, including the courses they intend to use, by the final study list deadline two quarters prior to the expected degree conferral quarter. The honors final report is due no later than the last day of classes of the quarter the student expects to graduate. More information can be found on the MCS Honors Website.
In addition to meeting all requirements for the B.S., the student must:

Maintain a GPA of at least 3.5 in all major coursework.

Students should complete 15 units of graduate level coursework. Included in these 15 units can be any of the following:

Related research from a 199 course

Participation for credit in a small group seminar

Directed reading


Complete a final report which should:

Include their name, degree and the title of their work.

Be typed with 12pt font, singlespaced, minimum 1 page (no longer than 2 pages) with a oneinch margin at the top and bottom of each page.

Explain a theme between the student’s coursework, their interests, and how they relate to MCS.

Describe how each course selected added to the student's knowledge and understanding in the chosen area of concentration.

The student's work must demonstrate indepth learning of a topic or shared idea in the breadth of the MCS major (examples are on MCS webpage), and all students are held to Stanford’s Honor Code.

COVID19 Policies
On July 30, the Academic Senate adopted grading policies effective for all undergraduate and graduate programs, excepting the professional Graduate School of Business, School of Law, and the School of Medicine M.D. Program. For a complete list of those and other academic policies relating to the pandemic, see the "COVID19 and Academic Continuity" section of this bulletin.
The Senate decided that all undergraduate and graduate courses offered for a letter grade must also offer students the option of taking the course for a “credit” or “no credit” grade and recommended that deans, departments, and programs consider adopting local policies to count courses taken for a “credit” or “satisfactory” grade toward the fulfillment of degreeprogram requirements and/or alter program requirements as appropriate.
Undergraduate Degree Requirements
Grading
The MCS program counts all courses taken in academic year 202021 with a grade of 'CR' (credit) or 'S' (satisfactory) towards satisfaction of undergraduate degree requirements and minor that otherwise require a letter grade.
