MCS will accept letter grade or credit for all major/minor courses for 2020-21 academic year.

Information about declaring MCS or MCS with Honors

Students should have taken 2 of the required Math courses (51-52-53) and either have taken or are currently enrolled in MATH 151 or STATS 116 (or another Statistics core course) prior to declaring MCS. If students have questions about the declaration process please meet with a peer advisor and email the MCS SSO.

Prospective students may meet with MCS Peer Advisors during office hours in Sequoia Hall room 124 and can request to join the mailing list.

Note that students are required to have a GPA of 3.0 to graduate.  Students with less than a B average upon declaration will be asked some additional questions and may have their major declaration held. Major declarations will not be approved if a student has an outstanding Incomplete on their transcript.
