Before reviewing the links, students should find their effective Academic Catalog Year. When clicking any links referenced below that take students to the Academic Catalog Year pages, they should be mindful of which Academic Catalog year is displayed.

  1. This optional course is highly recommended for freshmen, who may use it to help meet free elective requirements.
  2. MATH 220 may be substituted. MATH 220 is appropriate for students with no background in calculus.
  3. LAS 102 may be used for external transfer students. LAS 100 is supplemental course international students take along with LAS 101/102/122.
  4. RHET 105 (or an alternative Composition I sequence) is taken either in the first or second semester of the first year, according to the student's UIN (Spring if UIN is Odd). General Education Elective is taken the other semester. Composition I guidelines can be found at Degree and General Education Requirements under Written Communication Requirement.
  5. General education: Students must complete the Campus General Education requirements including the campus general education language requirement.
  6. CS 340 and two (2) CS technical electives (400 level CS courses) can be use to substiute the CS 233 and CS 341 requirements. The 2 technical electives must be distinct from courses used to satisfy other major requirements and can replace Free Electives.
  7. MATH 415 or MATH 416 may be substituted.
  8. Additional coursework, subject to College of Liberal Arts and Sciences restrictions to Free Electives, so that there are at least 120 credit hours earned toward the degree.
  9. In addition to the 5 groups, students must also choose one additonal 400 level CS or Math course. This must be distinct form courses used to satisfy your group requirements. Consult with your advisor to ensure you are meeting this requirement.
