Program rigor

This program is very rigorous and requires you to take ownership of your learning and time. For more details, visit the flexible academic plans webpage.

Math requirement

This computer science program includes one required math class. CS 225 Discrete Structures in Computer Science provides the mathematical foundation for students planning to enter software development and related fields. This course includes topics in Boolean and relational algebra, graph theory, inductive proofs, and combinatorics.

In computer science, math ability is often used as a demonstration of logical thinking. The discipline and ability to think through problems, break them down into simpler problems and apply transformations and rules that are needed to succeed in math is the same as that required to be successful in computer science. Some sub-areas require advanced math courses (e.g. graphics, scientific computing, machine learning, etc.), but most developers do not need upper level math courses.

If you plan to apply to graduate school in computer science or work in areas such as computer graphics, simulations, or game design, or bioinformatics, you may want to consider taking additional math and statistics courses.
